When the Number Comes Back Empty-Handed: The Discipline of a Table Tennis Analyst Facing a Blank Data Sheet

There was a morning in October when I sat in my usual corner of a coffee shop on Nguyen Thi Minh Khai Street in Saigon, holding a folder that should have been full of numbers. It was the data extract for a table tennis analysis project I had been assigned. I opened it, and there was nothing inside. No tournament name. No player name. Not a single number. Only one label had survived the entire processing pipeline: a line stating that the domain was table tennis. Every other cell was empty, or marked as having no value. The number knows how to hold its breath, and I wait for it to exhale. But this time, it did not exhale. It stayed silent in the way a ball drops onto a wooden floor without anyone hearing it bounce. I sat there for a long while, not out of confusion, but out of curiosity. An empty data sheet is also data. My question then was not "what is missing," but "what is this emptiness telling me about how an entire industry operates." Most people in the profession, when they encounter an empty cell, fill it with a guess. They write down the name of a match they vaguely remember. They assign some player a style of play that sounds entirely plausible. Their analysis sheet will look full, balanced, and as beautiful as a magazine spread. There is only one problem: it is not real. And in table tennis, as in every sport where points are measured in fractions of a second, the unreal soon reveals itself when the real ball is tossed up. I have worked as a data consultant for teams for over thirty years, many of them tied to table tennis and esports. Experience has taught me something few people want to hear: the hardest part of analysis is not finding the answer, but daring to say that you do not yet have enough data to answer. Beginners fear empty cells. Veterans fear empty cells filled with something that is not the truth. That day, instead of writing a fake analysis, I decided to write about the very analytical framework that had been left blank. About the nine dimensions that anyone who wants to understand a table tennis match at a professional level must pass through. And about why a correct framework is never enough, if there is no evidence to hang upon it. Old footage is a mirror, and only those who dare to look will see themselves. The mirror this time was a blank page. And I looked straight into it. To help you understand why I am using an empty sheet as a pretext to write a long article, I have to tell you how a professional table tennis analyst actually works. Not how people imagine it, but how it happens behind the door of the data room, where screens display ball speed charts, player movement paths, and numbers that seem meaningless to outsiders. Table tennis is a sport of distances. A forty-millimetre ball, weighing two point seven grams, travels back and forth across a table two point seven metres long. At the highest level, the ball takes about a quarter of a second to cross the length of the table. In that time, a professional player must read the spin, predict the landing point, choose the stroke, rotate the hips, and execute. This means the entire decision-making process happens faster than a blink. For a sport like this, analysis cannot be storytelling. It must be measurement. And to measure, you need three things: raw data, context, and patience. This article will walk through the nine dimensions of analysis that my colleagues and I still use when dissecting a professional table tennis match. But I promise you one thing: I will not pretend to be analysing a specific match. Because I have no match to analyse. And that very fact is the greatest lesson of today. The first dimension, and the foundational one, is technique, tactics, and equipment. It sounds dry, but this is where everything begins. When you look at a player, the first thing you must do is label their style of play. There are four main lines in modern table tennis: fast attack, loop drive, chop and block defence, and pips play. But a label is only a starting point. The real question is: how closely does this player play to their own label, and in critical situations, do they actually do what their style promises? I remember a year when I rewatched footage from a domestic tournament. A young player had been called by the media a "modern two-winged attacker." It sounded impressive. But when I played the footage back and counted, I found that at decisive points, he switched to short pushes and waited for his opponent to err in seventy percent of cases. The attacking style the press praised only existed when he was ahead. When he was behind, his true instinct was defence. That is the gap between label and execution. To measure that gap, you need numbers. The point-win rate when attacking first. The point-win rate on serve. The point-win rate after receiving serve and attacking first. The unforced-error rate in the deciding game. Without these numbers, every technical judgment is a blind guess in a tailored suit. That is why I am pained when I see a technical analysis sheet full of opinions but not a single number. Technique cannot be read with the naked eye. The naked eye is deceived by beautiful rallies. Numbers do not know beauty. They only know right or wrong. On the equipment side, table tennis has a history of changes that I always insist my students memorise. In 2026, the ball was increased from thirty-eight millimetres to forty millimetres. A two-millimetre increase sounds small, but it made the ball slower, reduced spin, and changed the entire scoring structure of the sport. In 2026, the rules changed from twenty-one points to eleven points per game. It sounds like just a number, but it turned every game into a sprint, where a single small error could end an entire game. In 2026, the hidden-serve rule was introduced, forcing the server to let the opponent see the ball, collapsing an entire generation of "invisible" servers. Then in 2026, the International Table Tennis Federation banned speed glue containing organic solvents. An entire generation of players who grew up with the feel of a ball accelerated by that glue had to relearn how to play. In 2026, the celluloid ball was replaced by the plastic ball. Every time the sport changes a material or a rule, one group of players loses an advantage they painstakingly built, and another group is born to benefit. That is why, when analysing equipment, I always ask two questions. First: whose strength is this change amplifying? Second: whose weakness is it compensating for? These are two completely different questions, and most people only ask the second. They see someone switch to a new rubber and play better, and immediately conclude that the rubber fixed the person's weakness. But sometimes, the new rubber simply hands them a weapon they never had, while the strength was already in their hands all along. Every number is a puzzle piece, but I do not assemble by habit. This means I refuse to join a technique piece with an equipment piece simply because they sit next to each other in the report. They must fit together through logic, through evidence, and through a story that can be verified. The second dimension is player data and head-to-head records. This is where everything becomes personal. Table tennis is a direct confrontation sport, where you stand less than three metres from your opponent. You are not only competing against an opponent; you are competing against the entire head-to-head history between the two of you. In my profession, there is a concept called the "nemesis." This is when a lower-ranked player regularly beats a higher-ranked player, because the lower player's style meshes strangely well with the higher player's weakness. To detect a nemesis, you cannot just look at the overall head-to-head. You must break it down by period. What do the last two years say differently from five years ago? Is the record at the three biggest events the same as at regular annual events? And most importantly, when in both careers did those wins and losses occur? A player may have lost five times in a row to an opponent, then won three times in a row after changing personal coach. The overall number will say five wins three losses for the other opponent. But the real story lies in where history turned. If you only look at the total number, you are reading a novel and skipping the final chapter. On ranking, I always teach my students never to trust a ranking without looking at the points history. In the World Table Tennis system, points are calculated on a rolling fifty-two-week basis. This means a player's points reflect not only how well they are playing, but also how many points they must defend from last season. Some players hold a high ranking only because their defence period has not yet arrived, and some players are dropping because they must defend too large a block of points. This is one of the biggest blind spots of the crowd. The crowd looks at the score; I look at the forgotten pass. In table tennis, the forgotten pass is the points history. A player on an impressive winning streak may be entering a period where they must defend points from two major events in the same month. That pressure does not appear on the news feed, but it appears in the player's head, and it appears in how they choose shots at important points. I once tracked a player through an entire season. The player's ranking was very stable, but the point-win rate at decisive points dropped noticeably in the two months before the points-defence period. Technically, nothing had changed. Physically, there was no sign of injury. The change was at another layer, the layer that only points history can see. That is why I tell my students: a ranking number without context is like a clock that shows the hour but not the date. The third dimension is the event system and points rules. This is the dimension I enjoy most, because it is where sport meets politics, commerce, and power. An event is not just a place where people hit balls. It is a machine for distributing points, money, and status. Modern professional table tennis is organised in a clearly hierarchical system. At the top are the Olympic Games and the World Championships. Then the highest-level events of the professional series. Then mid-tier events. Then continental and domestic events. Each tier has a different point value, and that value determines who qualifies for which event, who is seeded where, and who gets sponsored. What the crowd does not see is that an event does not only award points to the champion. It awards points on a gradient structure, distributed gradually from the champion down to those who reach the outermost rounds. This means that for a mid-tier player, going deep into a major event can be worth far more than winning a small event. A quarter-final berth at a high-level event can add more points than a title at a mid-tier event. That is why players enter major events not for honour, but for a calculation. Another point I always emphasise: major events often carry mandatory participation. This means that if you have a high ranking, you are obliged to attend, or you will be penalised points. This creates a system in which top players are not fully autonomous in scheduling. They cannot rest, because resting means losing points, and losing points means losing seeding, and losing seeding means facing strong opponents earlier. It is a spiral that only those inside the game fully feel. When analysing an event, the first question I always ask is: where does this event sit in the four-year Olympic cycle? An event held in an Olympic year has a completely different value from one held in the first year of the cycle. Events close to the Olympics often see an intense concentration of forces, because national associations use them as the basis for selection. Events at the start of the cycle are often where young players are tested, and where older players rest strategically. Time is something the news feed does not tell you. When I read an analysis sheet and see no specific dates, I immediately know the writer is trying to hide something. Perhaps they are not sure of the date. Perhaps they are using an old event to illustrate a new point. In any case, the absence of dates is a sign of an unreliable analysis. Table tennis changes month by month. An analysis without dates is an analysis floating in time, and floating analyses cannot be used to predict. The fourth dimension is the competitive landscape and the balance between powers. This is where I must speak about something that may surprise you: in modern table tennis, the dominance of one country is not uniform across events. Men's singles and women's singles are witnessing very different pictures. In women's singles, the gap between one dominant country and the rest of the world remains large. In men's singles, that gap is narrowing markedly, with more and more players from different countries reaching the deep rounds of major events. When I build a competitive map, I do not just list country names. I divide them into four tiers: the dominant tier, the second tier, the emerging tier, and the rest. The dominant tier is those who consistently have representatives in the semi-finals and finals. The second tier is those who regularly reach the quarter-finals but rarely go further. The emerging tier is those who have notable young players developing. And the rest are those who participate but have yet to make an impact. But I never stop at the map. A map only tells you the present, not the future. To predict the future, I must look at something else: the depth of the next generation. That is why I always track players under twenty-one. A country may be dominating at the top tier, but if none of their youth group is improving, that dominance will fade within five to seven years. Conversely, a country in the second tier with three or four excellent young players maturing may rise in the next cycle. The threat from opponents does not always have the same nature. Some threats are systemic, when an entire country builds a methodical training programme. Some threats are individual, when a gifted player appears and single-handedly stirs an entire generation. And some threats come from rule changes themselves, when a change unintentionally benefits a certain technical school. Reading the nature of the threat correctly matters far more than simply counting medals. The fifth dimension is rules and governance. This is the dimension I call the "underground layer," because it lies beneath the surface that fans see, yet it determines a great deal at the surface. In over thirty years in the profession, I have witnessed not a few times when a small change in the rules overturned the landscape of an entire generation of players. I have told you about the historical changes: the ball from thirty-eight to forty millimetres in 2026, the change from twenty-one to eleven points in 2026, the hidden-serve ban in 2026, the speed-glue ban in 2026, and the plastic ball in 2026. Each time, there were winners and losers. Interestingly, the winners and losers were not always who you would think. When the ball was increased from thirty-eight to forty millimetres, the beneficiaries were not the strongest attackers, but the players with the most stable chop-and-block game. Because the larger ball travels slower and spins less, a durable defensive style suddenly became viable again. When the hidden-serve ban was introduced, players who lived on deceptive serves had to relearn how to win points by other means. When speed glue was banned, those who relied on pure speed power lost part of their weapon, while those who relied on spin and control found themselves largely unaffected. This taught me a lesson I always pass on: the rules are not neutral. Every rule has beneficiaries and losers, and a good analyst must see both sides before the rule is applied, not after the results are settled. On selection, this is a delicate subject I always approach carefully. Whenever an association must choose someone to represent the country, there is controversy. The controversy flares more strongly when the selection criteria are quantitative, such as points and results, but are shaped by factors hard to measure, such as current form, experience on the big stage, or compatibility with teammates in doubles events. When a system selects based on numbers but allows a margin of flexibility for human decision, that margin is both a safety valve and a source of controversy. I never conclude that a selection decision was right or wrong based on the final result. Because a decision can be right in process yet still fail for reasons of chance, and vice versa. What I care about is whether the process is transparent, consistent, and evidence-based. A good process that fails is still a good process. A bad process that succeeds is just luck dressed in the clothes of achievement. The sixth dimension is coaching staff and the talent pipeline. This is where numbers meet people. In table tennis, the coach-player relationship is especially important, because it is a one-on-one relationship lasting many years. A personal coach does not just teach technique. They build the player's mental operating system, deciding how the player reacts to pressure, how the player handles failure, and how the player sustains motivation across many seasons. When assessing a coaching staff, I look at three dimensions. First is the head coach's ability and authority. This is the person responsible for the overall philosophy, event strategy, and personnel management. Second is the fit between the personal coach and the player. Sometimes a very good coach does not suit a specific player, because one person's way of communicating does not match the other's way of receiving. Third is the stability of the staff. A coaching staff that changes constantly cannot build a long-term system. On the training system, I always start with age structure. A healthy national team is one with a spread age structure, where there are mature players at their peak, young players improving, and mid-career players acting as a bridge. When there is a gap in the middle, for example the twenty-three to twenty-six age band with no significant names, that is a sign of a training gap whose consequences will appear in a few years. I have seen teams win with a squad of five players over thirty, and celebrate because they maintained form. But when I look at their under-twenty-three group, I see ten question marks. A top table tennis player's career lasts about fifteen years. If you have no one rising while the current generation is at its peak, you will pay the price in three years. The number knows how to hold its breath, and I wait for it to exhale. The gap in the age structure is the number holding its breath longest in my data room. The seventh dimension is the risk surface. This is the dimension I treat as a safety net, because it helps me prepare for the worst before it happens. There are six risk groups that I always check for any player. The first group is competitive risk: match volume, schedule density, and accumulated fatigue. A player who competes too densely may achieve good results in a few events, but the price is usually paid in the next event or in the decisive phase of the season. The second group is injury risk. Table tennis is a sport with specific injuries: wrist, elbow, shoulder, lower back, and knee. These injuries often do not force a player to rest completely, but they reduce the ability to execute at full range of motion, and this shows most clearly in heavy-spin rallies. The third group is technical-change risk. When a player decides to restructure their game, usually to adapt to age or rule changes, they must pass through a period I call the dark period, when the old is gone and the new has not yet taken shape. In that period, results usually drop, and many give up before getting through it. The fourth group is equipment-adaptation risk. When a player changes rubber or blade, they need weeks to months to regain the feel. During that time, accuracy can fluctuate. The fifth group is form risk. Even when healthy and without issues, a player can go through periods of declining form for mental reasons. This is the group hardest to see through numbers, but easiest to see through footage, if you know where to look. The sixth group is systemic risk: changes in rules, schedules, or association politics that can upend the plans of an entire group of players. Across all these risk groups, I always try to distinguish between risks within control and risks outside control. The crowd worries about both equally, and therefore worries excessively. A good analyst distinguishes what can be managed from what must be accepted. When I see a risk sheet where every cell is filled with vague fear, I know the writer is not really analysing, but worrying on behalf of others. The eighth dimension is public narrative and expectation. This is the dimension where I find many of the best technical analysts at their weakest, because they do not understand that professional table tennis today is a product of media, and media has the power to shape reality. A media narrative begins with an event, but it does not live on the event. It lives on emotion. When a young player beats an older player, the story is immediately constructed: the new generation is rising, the throne is changing hands. But if you look at the numbers, you may see that the older player had just come through a tiring event, was in a points-defence period, or simply lost a game they had won nineteen times out of twenty before. I always analyse a media narrative with three questions. First: how many samples is this story based on? One win does not make a trend. A streak of three wins begins to be meaningful. And a streak of ten wins is worth analysing. Second: is this story exaggerating a random event into a rule? Third: is this story serving some interest, such as selling tickets, attracting sponsorship, or building an image? Media narratives always follow a cycle. It buds when a new event occurs. It accelerates as it spreads. It peaks when everyone believes it. And it rebounds when reality does not match expectation. A good analyst is one who knows where in that cycle they are, and knows that the truth often lies far from both the peak and the rebound. There is something I want to say about handling sensitive rumours. In this profession, I have encountered every kind of rumour: about match-fixing, about disputes within national teams, about secret retirements, about hidden injuries. I have learned one principle: before believing a rumour, rank the source. If the source is a major established newspaper, the chance of accuracy is higher. If the source is an anonymous social media account, the chance of error is far higher. And if the source cannot be identified, it is best neither to confirm nor deny, but simply to record that a rumour exists, and to wait. Waiting is a legitimate and necessary analytical tool. The ninth dimension, and the final one, is the transmission of the table tennis industry. This is where a small ball meets a large economy. Table tennis is not just matches. It is a value chain running from equipment manufacturers to training centres, to events, to broadcasting, to commerce, and finally to fans. Upstream, you have brands making blades, rubber, balls, and tables. Their sales depend on how many people play table tennis worldwide, and which brand those players trust. When a top player signs with a brand, it is not just an advertising contract. It is a signal to an entire market that the brand is trustworthy. The star effect in table tennis is strong, because amateur players tend to choose the equipment their idols use. Midstream, you have events, associations, and clubs. This is where money and power meet. A commercially successful event is one that attracts sponsorship, sells broadcasting rights, and has an audience. But a competitively successful event is one with the participation of the strongest players. These two goals do not always align, and that is why the event system is always a balancing act. Downstream, you have media, commerce, and derivative markets. Fans do not just watch table tennis. They share, they comment, they buy merchandise, they invest their faith in a specific player. This is where a player's commercial value is determined, and it is not always proportional to their competitive value. There are players who are not world number one but have greater commercial pull than the number one, because they have style, a story, and the ability to connect with the audience. My data café is busiest when the stadium is empty. That is when I sit alone with the numbers and try to understand what laws this value chain is operating by. When the stadium is full, everyone reads the news feed. When the stadium is empty, only the truly curious stay to ask questions about the things that do not appear on the news feed. And that is why I return to my empty data sheet. After going through nine dimensions, I realise I still cannot make any judgment about a specific match. But I can make a judgment about the work of analysis itself. And that judgment is: in an industry where everyone wants an answer, the best are those who know how to hold back the answer until there is enough evidence. This is the counter-intuitive angle I want to dedicate the final part of this article to discussing. The crowd, when handed an analytical framework, tends to fill it with whatever they can, because an empty framework looks like a failure. They think their value lies in producing content, and content must be full. But in sport in general and table tennis in particular, producing empty content is one of the hardest and most valuable decisions an analyst can make. I call it the discipline of emptiness. It requires you to resist three pressures at once. The first pressure is the pressure to have an answer. In modern work environments, silence is considered weakness. But in analysis, silence is sometimes strength. The second pressure is the pressure from the crowd. When everyone around you offers an opinion, you feel you must follow suit to avoid being left behind. But following the crowd in analysis means repeating their mistakes, not analysing. The third pressure is the pressure from yourself, from the desire to prove you are useful. This is the most dangerous pressure, because it comes from within, and it never goes away. The crowd thinks a good analyst is someone who always has something to say. I think differently. A good analyst is someone who knows exactly when to speak and when to stay silent. The difficulty is that the line between those two moments is not drawn by feeling, but by evidence. You are only allowed to speak when the evidence is thick enough. And you must stay silent when the evidence is thin, no matter how much noise there is outside. There was once a time when I sat in a meeting where the whole room was discussing tactics for a big match. Everyone offered many opinions, each sounding reasonable. When it came to my turn, I said I did not have enough data to conclude. The room went silent. Someone laughed and said this was a tactics meeting, not an apology meeting. I replied that yes, this was a tactics meeting, and in a tactics meeting, offering a tactic based on insufficient data is more dangerous than offering no tactic at all. Afterwards, I spent the next two days gathering the data I was missing, and when I returned, I gave a specific, evidence-based recommendation that led to a good result. The lesson from that story is not "I was right." The lesson is: temporary emptiness can be a stepping stone to a solid conclusion, if you know how to fill it with real work rather than with words. Now, I want to talk about an aspect I call the silence between numbers. In table tennis, as in any sport, the most important numbers are not always the ones recorded. Sometimes they are the ones not recorded, or recorded clumsily, or buried under a pile of other data. For example, when you watch a table tennis match, you see the score. You see who wins and who loses. You see beautiful rallies. But you do not see the rest time between points. You do not see how many times a player wipes sweat before serving. You do not see the interval during which a player looks into space before executing a decisive shot. Those silences contain a great deal of information about the player's mental state, about the tactics the coach is trying to convey, and about how a player handles pressure. I once spent an entire season just recording these silences. I recorded the time between points, the preparation time before serving, and small changes in body language. The results were astonishing. There were players whose extended serve preparation signalled that they were losing confidence. There were players whose shortened time between points signalled that they were in a state of peak form. These signals never appeared on the scoreboard, but they predicted outcomes better than point-win rates. That is why I always tell my students that data is not just what is recorded. Data is everything observable, and the analyst's job is to expand their scope of observation to the things others overlook. Old footage is a mirror, and only those who dare to look will see themselves. And I have looked into many mirrors throughout my career, not to find where others were wrong, but to find what I had missed. I used to fear the microphone; now I let the data speak for me. There was a period in my career, when I was invited to commentate on television, when I made a mistake I still remember to this day. In a major match, out of excitement, I mispronounced a player's name several times. The audience reacted, and I was so ashamed I wanted to leave commentary. But instead of quitting, I decided to relearn from scratch. I spent the entire following month rewatching every piece of footage from the event, not to commentate, but to observe. And it was during that process that I discovered a defensive pattern in a national team with a particular gap behind the wing defenders, a gap hard to see with the naked eye but appearing repeatedly in the footage. That discovery did not come from talent. It came from patience. It came from accepting that I had been wrong, and using that very mistake as the starting point for a new learning process. From then on, I added to my analyses something I call the "movement data layer": not just recounting events, but pointing out gaps, running distances, and small movements others overlook. I write slower, but more accurately. This is what I want you to take with you after reading this far: in a world where everyone wants an answer immediately, patience is a competitive advantage. Not slowness, but deliberate patience. Patience to wait until the data is thick enough. Patience to distinguish correlation from causation. Patience to recognise that an empty sheet is not a failure, but an invitation to go find more. On the relationship between correlation and causation, this is a trap I have seen countless times in the profession. A player changes rubber and wins three events in a row. Everyone concludes that the new rubber brought success. But perhaps that player also just changed coach, also just rested enough to recover from injury, and also just met an easier draw. The truth is, at least four factors changed in the same period, and attributing success to a single factor simply because it is the most visible is a common mistake. I always teach my students one principle: when two things change together, do not rush to conclude that one caused the other. Look for more evidence. Look for a case where one changed and the other did not. See whether the relationship appears in other players. Only when you have ruled out alternative explanations do you have the right to say you have found the cause. This is especially important in table tennis, because the sport has too many variables. A match is shaped by technique, fitness, psychology, tactics, equipment, officiating, playing conditions, and luck. If you try to explain an entire result with a single variable, you are doing something I call "dangerous oversimplification." It may sound very convincing in a short article, but it will collapse when you apply it to the next match. So, how do you distinguish a real analyst from a storyteller with numbers? The answer lies in the attitude toward uncertainty. A storyteller with numbers will use the number to confirm the story they wanted to tell from the start. A real analyst will let the number lead the story, even if that story differs from what they expected. When I begin an analysis, I always remind myself that my hypothesis may be wrong. And if it is wrong, I must have the courage to abandon it. That is why I always keep a notebook recording my hypotheses, along with dates and the evidence at the time. When I check the notebook later, I can see where I was right and where I was wrong. This is not a habit for self-praise. It is a habit for self-checking. Because the mirror I look into is not only footage of others, but footage of myself. I want to return to the biggest question of this article: what is an empty data sheet telling us? And I want to give my answer, not as a summary conclusion, but as a thought moving forward. In over thirty years in the profession, I have watched sports analysis go from a manual job of a few enthusiasts to an industry with thousands of people, millions of data points, and machine-learning systems that can process billions of data points in seconds. We live in an age where data has never been so abundant. But I want to say that precisely because data is so abundant, the discipline of emptiness has become more important than ever. When data was scarce, analysts knew exactly what they had and did not have. When data becomes infinite, analysts are easily dazzled and forget the simple truth that: more data does not mean more information, and more information does not mean more understanding. An empty data sheet, in this age, is a reminder that beneath every table and chart, there is always a foundational question we must not forget: am I truly understanding what I am saying? I think that in the future, the value of a table tennis analyst will not lie in the ability to process data, because machines can do that better. It will lie in the ability to ask the right questions, in the ability to recognise when one lacks information, and in the ability to stay honest under the pressure to give an answer. The crowd will continue to rush after new tool trends. But those who go against the crowd through architecture, not through movements, will be the ones building truly sustainable foundations. As for my empty data sheet, I have made a decision. I will not fill it with imagination. I will note it down, with specific dates, with a note on the source, and with a line I teach my students to write whenever they encounter a situation like this: insufficient data to conclude, need to collect more. This is not a failure. It is an honest act. And I believe that, in an industry where numbers can be distorted in countless ways, honesty is the most valuable asset an analyst can possess. That night, I closed the folder and walked out of the coffee shop. Saigon was still lit up, and in my head the question about the empty data sheet was still ringing. I wondered: if every analyst in this industry, each time they encountered an empty cell, instead of filling it with a compelling story, spent an extra thirty minutes searching for real data, where would sports analysis go? I do not have an answer to that question. But I know one thing: I will be one of those who spends that extra thirty minutes. Every day. And I will wait for the number to exhale, no matter how long it holds its breath. The final question I want to leave you, the reader who has come this far: when you look at a full sports analysis sheet, are you seeing evidence, or are you seeing confidence arranged neatly? And if there is an empty cell in that sheet, do you have the courage to say you do not know, rather than filling it with an answer that sounds plausible? That is the question I still ask myself after every analysis. And perhaps, that is the question anyone who does this work with respect for the truth must ask themselves.
