The Hollow Report: How the Sports Industry Fools Itself With Numbers That Do Not Exist

One March morning, I opened a report that had landed in my work inbox. Beautiful cover. Beautiful typography. A logo, a chart, a bold title: "Assessment of Sponsorship Effectiveness for the Season." Page two was a table of contents. Page three was an executive summary. From page four onward came the body. Eighty-two pages. Not a single verifiable figure beyond a handful of percentage points with no stated source. Not a single contract cited. Not a single date fixed. I read all eighty-two pages in forty minutes, and when I closed it, I knew exactly one thing: the person who wrote it did not want me to know anything at all.

I tell this story not to criticize an individual. I tell it because after fifteen years in the industry — as an esports athlete, a tournament organizer, and now a club financial analyst in Incheon — I have recognized that the hollow report is not the exception. It is the standard. It is a genre with its own structure, its own grammar, and its own purpose: to look like analysis while protecting its author from any accountability whatsoever.

And here is the problem: a report with no data is more dangerous than a report with wrong data, because it asserts nothing true or false — it merely manufactures the sensation of having been reviewed. When an executive holds a thick stack of paper, he feels reassured. When a board sees a table of contents, it feels that process has been followed. That sensation is what is being sold to us every season, every transfer window, every time broadcast revenue is announced.

The story of those eighty-two blank pages is the starting point. But to understand why it exists, we have to walk backward into the power structure of the industry — who pays whom, who needs whom to stay blind, and who benefits when a number is never asked where it came from.

I started in 2026, as an esports athlete, then a tournament organizer. Back then we had no reports. We had Excel, sticky notes, and phone calls at two in the morning. When I moved into esports media, I kept the habit — every number had to show where it came from, who wrote it, when, and how. In 2026, when I entered a mid-level financial analyst role at Incheon United in the K-League, I brought that habit into a world where it was considered abnormal.

Korean professional football, like most of the global sports industry, runs on a strange kind of faith: numbers repeated often enough become facts. One outlet reports "global broadcast revenue reached X billion." Ten others quote the first. Three weeks later, X billion becomes a benchmark. No one goes back to check where the first outlet got it — maybe a press release, maybe a conference slide, maybe an interview from seven years ago when the contract structure was entirely different.

This is the core power structure we must look at directly: the sports industry does not lack money. The sports industry lacks people who read financial statements. There is an enormous gap between decision-makers — club presidents, tournament organizers, federations — and the people holding raw data. That gap is filled by an intermediate form of writing: the report. And because the gap is so wide, because no one in the meeting room has time to audit every figure, that intermediate report can contain anything without anyone noticing.

I once thought esports would break this structure. Esports grew up with data. Every match, every pick, every kill is logged automatically. I thought that when an entire industry runs on machine logs, the hollow-report habit would vanish. I was wrong. And that mistake taught me more than any success.

Esports is not football's rival. It is a mirror exposing the entire spending habit of this industry. Esports has a hundred times more data than football, and it still produces hollow reports just the same — except now they come with prettier charts and more expensive dashboards. If abundant data still fails to produce truth, then the problem was never a lack of data. The problem is motive.

There is a model I built in 2026 that I have never told publicly. At twenty-nine, I was a mid-level financial analyst at Incheon United. I built a valuation table combining social-media follower growth with on-pitch performance metrics. Nothing sophisticated — statistics, correlation, simple regression. But when I ran the data, I found a twenty-three-year-old midfielder named Kim Do-hyuk with 214 percent Instagram follower growth over six months. That was three times any player with the same professional metrics in the league.

His commercial value was untapped. I wrote a report. I brought it to the meeting. Management rejected it. The reason given: "This is a fan game, not serious football business." I stayed silent, went back to my desk, and wrote three more versions of the model. One assumed Instagram ceased to exist. One assumed growth halved. One assumed every follower was a fake account. All three, under the most pessimistic assumptions, still showed his commercial value was underpriced.

The first lesson about hollow reports came from here, not from being right. Management did not reject it because my model was wrong. They rejected it because my model forced them to face a question no one wanted to answer: if we can measure a player's commercial value with social data, why do we pay players using a different formula — one proposed by agents, inflated by media, decided by a president's gut feeling?

Every valuation model is wrong. The question is: wrong in whose favor. My model was wrong in a way that favored the club and the player. The traditional model is wrong in a way that favors those earning commissions on every deal. This is the deeper reason hollow reports exist: a report with no data cannot be proven wrong, and therefore cannot be used to change the existing order.

In 2026, at thirty, I was assigned by the CEO to track the sponsorship effectiveness of the Korean Football Association during the Russia World Cup. This is where I learned to use the macro data of a major tournament to challenge old revenue models.

Korea versus Mexico, June 23, 2026, ending in a 1-2 defeat. I sat in front of a screen, logging every metric. 4.2 million online views. Engagement spiked. But when I pulled jersey-sales data, the number went the other way: down 17 percent year over year. I brought both figures to the meeting and was treated as a troublemaker.

What I said then — and still defend today — is that the traditional broadcast-licensing model was missing 11 billion won in digital-platform revenue. People looked at me as if I had insulted a national heritage. But World Cup broadcast revenue is the prettiest number in the world when you do not ask where it came from. Licensing contracts are signed in blocks, by region, by package, and most published figures are estimates or aggregates spanning multiple periods. When I asked how each part was allocated, the answer was: "That figure is internal information."

Internal information. Those two words are the industry's border. Every hollow report is erected at that border.

I proposed five new digital exploitation scenarios. I argued for weeks with the communications department. None were implemented that World Cup. But I learned something more valuable than any victory: how to ask "what does this number actually reflect" instead of accepting the report as presented. 4.2 million views is not a fact. It is a fact detached from context: how many were first-time viewers, how many rewatchers, how many shared accounts, how many gyms leaving the TV on for customers. Peel away enough layers and the number can shrink to a third.

And when a number shrinks, the next question appears: why was it published inflated? Not by oversight. Because an inflated number benefits everyone in the supply chain — federation, broadcaster, sponsor, player negotiating a contract. A hollow number, by contrast, benefits whoever wants everything to stay the same.

In 2026, at thirty-two, the pandemic hit and the stadiums went empty. Incheon United projected a 12 billion won loss in ticket revenue. The whole industry plunged into a crisis everyone called "unprecedented." I called it something else in an internal meeting, and that name got me in trouble.

I called it an opportunity. Right after that, I added: "This is an opportunity to see the models that died long ago."

The year 2026 did not destroy football — it wiped out models that had died long before. A club dependent on matchday revenue is a club that was never truly in the football business; it was renting a stadium and selling tickets. When the doors shut, the model died. It died in March 2026, but on paper it died around 2026, when the share of ticket revenue began falling and no one wanted to draw that line on a chart.

I organized a brainstorming session with six marketing staff. We proposed four new revenue models: virtual advertising on broadcast, per-angle match tickets, community fundraising, and short-term per-match sponsorship deals. Two failed. Virtual advertising brought in 1.5 billion won in three months, and Seoul E-Land quickly copied it. Per-angle tickets sold nothing. Community fundraising had a small burst, then faded. Per-match sponsorship performed at an average level.

But here is what I want to say about that period: an empty stadium is a laboratory. When the crowd is gone, everything else becomes measurable. You measure the value of a broadcast minute without the noise of cheering. You measure the value of a broadcast moment without the crowd blocking it. You measure the true loyalty of fans, because only those who genuinely care remain. Empty stadium = laboratory. The report is on my desk, and it is entirely different from the eighty-two blank pages I opened this story with.

The difference between the two reports? The hollow report was written to defend a decision already made. Mine was written to find a decision not yet made. One serves the existing order. One serves breaking it.

I tell these three stories — the 2026 player valuation model, the 2026 licensing rebuttal, the 2026 empty-stadium lab — not to say I was right. The opposite. I tell them because I want to show that even a person with the habit of auditing every number, working inside the system, still gets pushed to the margins. I was not fired. I was simplified: a difficult person, someone always demanding sources, someone overdoing it. In sports corporate culture, being called "difficult" is worse than being called a failure, because a failure can learn, while a difficult person must be avoided.

That taught me the problem is not the individual report writer. The problem is structural motive. To understand why hollow reports are so widespread, we must look at four basic motives driving their production.

Motive one: publishing is safer than not publishing. In sports, an analyst who does not publish is deemed useless. An analyst who publishes a correct but controversial report is deemed dangerous. An analyst who publishes a hollow report is deemed professional. They "worked." They "provided perspective." They offended no one. This is the incentive scale every large corporation runs on, and sports is no exception.

Motive two: a wrong number can be proven wrong; a vague number cannot. When you write "revenue grew significantly," you cannot be caught. When you write "revenue grew 12.3 percent," people will demand the spreadsheet. So the writer's optimal goal is not to be right, but to be unprovable. This is the point I will return to at the end, because it contains a frightening paradox.

Motive three: a report is a product, not a process. A report is commissioned to impress. It must have enough chapters, appendices, charts. Thickness is a quality metric in corporate culture, which is entirely opposite to scientific thinking, where a two-page paper can change an industry and a hundred-page paper can say nothing. The hollow report is not a failure. It is a product optimized for precisely the wrong metric.

Motive four: data sources are often unverifiable or prohibited from verification. Sponsorship contracts have confidentiality clauses. Licensing contracts have confidentiality clauses. Player salaries have confidentiality clauses. Transfer fees are often published in aggregate without payment structure. In such an environment, any number can stand on the foundation of "a source who declined to be named." And when ultimately every number can hide behind confidentiality, the difference between a real number and a fabricated one is thin — both are immune to external verification.

These four motives explain why the hollow report is not an accident but a default. They also explain why the sports industry, despite moving tens of billions of dollars annually, still operates on less verifiable information than a mid-tier franchise coffee chain.

I want to return to another story, because it shows the problem is not limited to internal reports.

In 2026, at thirty-four, the Qatar World Cup took place mid-European-season. It was a strange schedule, and strange schedules create valuation gaps. I leveraged an agent network built since 2026 to analyze a loan deal: Senegalese midfielder Ibrahima Ndiaye, twenty-six, shining in the group stage with two goals and one assist in three matches, but undervalued by his parent club in Ligue 2.

I persuaded Incheon United to sign a six-month loan with a 60-40 wage split. Ndiaye scored seven goals in the second half of the season and helped the team survive relegation. The story was reported as a scouting triumph. But that is not what I think when I look back.

What I think is: players have no price — they have stories, and the market does not know how to read them. Ndiaye was cheap not because he was poor. He was cheap because his parent club had no one analyzing his social data, no one measuring how much his name searches rose after each group-stage match, no one noticing that a country of seventeen million people had just gained a World Cup star not starting for a second-division French club.

That gap is where the hollow report truly does damage. Not in the meeting room. On the pitch. Every time a club lets a player like Ndiaye slip through because it has no valuation system beyond "the owner likes this guy," it is leaving money on the table. And to justify having no system, it produces a report. A hollow report. A report saying this player "needs more time," "does not fit the team culture," "has an incompatible style."

The transfer window is not a market — it is a war between the spreadsheet and the ego. And in that war, the spreadsheet almost always loses, because the spreadsheet needs transparency, while the ego needs a hollow report to defend itself.

Now I want to face something more uncomfortable: I myself have written such reports.

Not many. But some. In 2026, I submitted an assessment of a sponsorship deal's effectiveness, and I left five blank lines in the data section because I had no access to regional sales data. I wrote that the sponsorship "contributed positively to regional brand recognition." I knew what I was doing when I wrote that sentence. I knew it was a sentence that could not be proven wrong, and therefore could not be challenged. I wrote it because I needed to submit on time, because I had no data access, because I did not want to be the only one saying "I don't know."

That was one of the most shameful moments of my career. Not because of the report. Because I did the thing I always criticize — using vagueness to avoid truth. And in doing so, I saw clearly that the hollow report is not a matter of personal ethics. It is a consequence of a system where "I don't know" is an unacceptable answer.

In sports, when you say "I don't know," you are deemed incompetent. When you say "I don't have enough data to conclude," you are deemed evasive. When you say "I cannot confirm this number," you are deemed obstructive. So people learn to say something that looks like an answer. They write "significant effect," "positive trend," "stable growth momentum." They do this until the whole industry speaks the same language — a language with all the structure of analysis but none of the components of truth.

There is a subtle trap here, and I want to take a paragraph to make it clear, because I see many analysts fall into it. When you build multiple parallel models and one turns out right, you begin to believe you can see ahead. That is a self-satisfaction trap. I once thought I read Ndiaye right, Kim Do-hyuk right, digital revenue right. But if I only remember the times I was right, I am doing exactly what the hollow report does: curating to create a story that cannot be proven wrong. The real test is not how often you are right. The real test is whether you are willing to record your wrongs with the same level of detail as your rights.

Between two reports — one boasting three successful deals and one recounting both three successes and two failures — the second is many times harder to write. And precisely because it is hard, it is rare. And precisely because it is rare, it is almost never produced in the sports corporate process, where everything must serve a single goal: making no enemies.

There is one thing I learned from looking at esports and football simultaneously, and it changed how I see the whole problem.

Esports has data. A lot of it. A tournament can give you win rates by champion, pick-ban rates, climb speeds, every metric down to the thousandth of a second. It is an analyst's paradise. Yet esports still produces hollow reports identical to football's. The reason is simple: on-pitch data is entirely different from on-desk data. Match data serves coaching. Financial data serves decisions. And in esports, as in football, financial data is locked inside contracts no one is allowed to publish.

An esports team can win three tournaments in a row and still no one outside knows whether it is actually profitable or losing money. What sponsors pay. How prize money is split. What structure transfer fees follow. All in the confidential zone. And when every number is confidential, the industry automatically fills the gap with numbers of its own making — numbers serving media more than truth.

This is why I say esports is not football's rival. It is the same disease, in a younger body. And it gives us a natural experiment: if an industry with too much data still produces hollow reports, then the cause of hollow reports is certainly not a lack of data. The cause is a lack of motive to publish truth.

Seen from that angle, everything becomes clear. The hollow report is not a product of ignorance. It is a product of a specific incentive system where the honest are punished and the vague are rewarded. Such a system cannot be fixed by adding more data. It can only be fixed by changing the incentive structure. And the incentive structure does not change just because one person decides to be honest.

---

So what can change?

I do not believe in general moral appeals. I believe in mechanisms. There are three specific mechanisms that can shrink the space for hollow reports, and we tested some of them in our work.

Mechanism one: force every number to carry three fields — source, date, and responsible person. Not to punish, but to create a traceable trail. When every number in a report must declare where it came from and who confirmed it, the cost of writing a vague number rises significantly. We tried this in an internal project. The result: writing time rose about forty percent, and page count fell about half. Most of the cut content was content without sources.

Mechanism two: add "not enough data to conclude" to the list of permitted answers. It sounds trivial, but the impact is large. When an analyst is allowed to write "not enough data" without being deemed incompetent, he will write fewer hollow reports, because the hollow report is mainly a way to mask a lack of data. If there is no need to mask, why mask?

Mechanism three: publish a list of unanswered questions. Every report must include a final section stating what it cannot answer and why. This section is often the most valuable. It points exactly to where the club, league, or federation is blind. And in sports, value lies precisely where the light has not yet reached.

I tried all three at varying levels. None was a miracle. The first failed at its initial rollout because departments refused to declare sources. The second was deemed "an excuse for laziness." The third survived in some reports, then vanished when the project lead changed. This is the reality of reform in sports: it does not fail because of open opposition; it fails because it is quietly faded away.

But I still believe in those three mechanisms, because they point to one truth: the problem is not that people do not know how to write good reports. The problem is that the system does not reward it. Changing the reward system is harder than changing people, but its results last longer.

---

Now I want to say something I know will be uncomfortable, and I say it after long thought.

The truth is: in some cases, the hollow report is the best available choice under current circumstances.

Let me explain. If you are a mid-level analyst at a Korean club, with no access to the financial system, no right to interview the commercial department, and you are assigned a report on sponsorship effectiveness in two weeks — you face two choices. One: write a report with three numbers estimated from press data, high risk of being wrong and possibly used to criticize the club. Two: write a report with vague language, qualitatively correct, impossible to fault, and honestly reflecting that you lack the access to answer the assigned question.

In that situation, the second choice may be the more honest one. It does not lie. It only says the question cannot be answered with existing resources. The problem is the system does not read it that way. The system reads it as an answer, nods, and moves on. And so the hollow report — a desperate letter written in polite language — gets recycled into a legitimization.

This is the paradox I mentioned above. A vague number cannot be proven wrong — but precisely because it cannot be proven wrong, it can be twisted to serve any purpose. A hollow report is essentially a gap. And a gap, in an organization, is always filled by the most powerful person in the room. The report is not neutral. Its emptiness is a false neutrality, and every false neutrality has an owner.

So the real paradox is not "is the hollow report good or bad." The real paradox is: the hollow report is written to protect its author from misunderstanding, yet it becomes a tool for others to misunderstand everything. It starts as a shield. It ends as a weapon. And its author, usually, never knows that transformation happened.

I have worked in the industry for twenty-two years, counting from the first time I stood in the room of a small esports tournament in Vietnam to today, sitting in Incheon, writing these lines. In those twenty-two years, I have read thousands of reports. I have written hundreds. I have signed my name under some I am not proud of. And what I take away is not that sports is deceitful. What I take away is that sports has no mechanism to distinguish between truth and something that looks like truth — and in that gap, the thing that looks like truth always wins, because it is cheaper, faster, and costs no one a job.

So what should fans do?

This is the most important question, because I write for fans more than for industry insiders. Insiders already know what I just said. They simply do not say it. Fans do not know, and precisely because they do not know, they are the ones who pay last — in trust, in ticket money, in loyalty to stories built from numbers with no source.

There is a simple habit any fan can adopt. Every time you read a number about sports, ask three questions. Question one: where did this number come from? Question two: who benefits from this number being published in this form? Question three: if this number is wrong by half, what changes in the story I am reading?

Those three questions need no financial knowledge. They need only the habit of suspicion. And in sports, the habit of suspicion is a survival skill — not to become bitterly cynical, but to preserve genuine joy. Because joy built on a fabricated number collapses when that number is replaced. Joy built on a truth, however smaller, lasts longer.

A club does not need a full stadium to make money. It needs to know what an empty stadium is saying. And a fan does not need to believe every number to love their team. They need to know which numbers to trust, and which are being used to sell them a story.

That night, after closing the eighty-two-page report, I sat alone in the office. I opened a blank file and started writing something else. I wrote out every question the report had failed to answer. I listed every number it mentioned but did not explain. I marked every passage that could be cut without losing any information. When I finished, that file was about seventy times shorter than the report, and it contained more truth than any page of those eighty-two.

I sent it to no one. I kept it for myself, as an exercise. And I keep doing that exercise every time I read a report — someone else's, and my own, past and future. Because I have come to understand that the job of an analyst is not to produce beautiful numbers. The job of an analyst is to produce questions that no number can bury.

The sports industry is fooling itself with numbers that do not exist. And the only way to stop fooling itself is not to produce more numbers, but to learn to stand before a gap and say: here I do not know. Here I need more data. Here my report is worthless.

Those three sentences are harder to say than any others in the industry. And precisely because they are hard, they are the only ones worth starting with.
