The Empty Data File and the Ethical Limits of Football Commentary

I opened a file that night and there was nothing inside it. No headline, no author, no line of data. Only a nine-part analysis template, and in every empty field the same repeated line: insufficient information to conclude.

In a newsroom, the first reflex is always to fill the gap. An editor needs a piece. An audience needs a name. A report with no conclusion is like a match with no goals — people still watch it, but nobody remembers it.

I used to write on that reflex. In 2026, while I was a journalism student in Busan, I sat in the press stand at a K League 2 match and logged fourteen fouls. The referee repeatedly waved away shirt-pulls inside the box, most clearly in the 67th and 82nd minutes. I stayed four hours with slow-motion footage shot on my phone, recounted the assistant referee's every footstep, and found a pattern: every time the number 9 striker ran diagonally off the left flank, the assistant was exactly one beat late.

That was the first time I understood that a verdict only has value when it is built from something you have counted. The silent whistle at 23:47 is a sentence — but only when I know exactly what I am counting.

An empty file is not a technical glitch

That file is a miniature of a habit that is eating away at football analysis: verdict first, evidence afterwards. The habit is not born of laziness. It is born of time pressure — something anyone who has sat in a newsroom at eleven at night understands.

Look at the transfer window now open and the habit is at its most visible. A player is spotted having dinner in a city, and within six hours ten articles claim he is about to sign. Few of them wait to see whether a medical is even scheduled. Few check how many years the selling club still holds on the player, which currency the release clause is written in, and who actually receives the money. Transfer noise drowns out signal, and the reader is left in a room full of echo and not a single wall.

In Vietnam, that pressure has its own colour. Vietnamese football operates inside a young, fast media ecosystem that is acutely sensitive to public emotion. When VAR began appearing in domestic professional leagues, it carried a promise: technology would quieten the arguments. Reality went the other way. Every time a referee walks to the monitor, the volume of argument rises, because viewers are handed something more dangerous than the truth — an image that appears sufficient to pass judgement.

I have watched matches in both markets, and the difference sits here. Korean audiences usually interrogate process — did the referee review the right incident, was the stoppage well timed. Vietnamese audiences usually interrogate the verdict — the flag is up, so is it right or wrong. One side asks about how the law was read. The other asks about the final outcome. Both are reasonable, but only one produces data that improves the next time.

The VAR protocol is a lesson in silence

Read the IFAB Laws of the Game closely and a detail emerges that most viewers skip. VAR was not designed to correct every error. It was designed to intervene on clear and obvious errors, or on missed serious incidents. The intervention threshold was written not to protect referees from criticism, but to protect the match from being shredded into hundreds of replays.

Which means the protocol contains a valid outcome called no intervention. Not every suspicious moment must produce a new decision. There are situations where the correct answer is to leave the field as it is and let the game flow on.

There is an exercise I still give to interns: pick a match and log every moment the referee stands still. Not the times he blows the whistle, but the times he places a hand on his chest and waits. In the first fifteen minutes they usually record two or three lines. By the sixtieth minute they have a list. The still moment is where the decision is formed — before the arm goes up, before the whistle sounds. Viewers only see the outcome. An analyst has to see the silence standing in front of it.

This is where my craft and the referee's craft meet. The law is never wrong; only the reading of the law is wrong. When a referee is criticised for not giving a foul, the problem rarely lies in the wording of the law. It lies in the lens through which he read the incident — too strict, too lenient, or too afraid of the consequences. And when a writer is criticised for a wrong conclusion, the problem rarely lies in the data. It lies in the expectations through which the writer read the data.

There is a line I still use when talking to younger colleagues: there are 22 players on the pitch and only one man who is not allowed to be wrong. Read closely, that line is not entirely true. Referees are allowed to be wrong. What is not allowed is a wrong process. A wrong decision caused by a human being with a limited angle is an occupational accident. A wrong decision caused by skipping a check is a system failure. And system failures repeat. VAR does not correct referees, it only exposes their fear.

Three layers of verification Vietnamese football writing is missing

The layer most easily skipped is source verification. In a transfer window, information should be tiered. An official club statement carries a different value from an agent's social post, and a very different value from an unsourced round-up. Agents have their own motives: to push a price, to create pressure, or simply to keep a client's name in the news flow. Identifying motive is not suspicion. It is the minimum courtesy owed to the reader.

The harder layer is structural verification. A real deal usually leaves administrative traces: registration timing, release clauses, wage bill, foreign-player quotas. When a club stays completely silent while a rumour detonates, that silence is data. When a player is absent from an open training session but present at a commercial shoot, that presence is data too. I learned this from reading match data: the most useful information is rarely the loudest, it is the most consistent.

The layer outsiders fail at most often is cultural verification. A decision can be lawful and still wrong for the football reality in which it is made. Vietnamese referees carry different pressures from Korean referees: fixture density, travel distances, media scrutiny, and the way a stand reacts. Treating Vietnamese football through a purely European lens is the fastest way to write a rootless analysis. Treating Korean football through a purely Vietnamese lens is the same mistake in reverse. A writer has to know where he is standing.

The empty file is the most honest document in the newsroom

We usually treat emptiness as failure. Try changing position once. A file with nine sections, each stating plainly that the data is insufficient, tells the reader more than any analysis stuffed with conclusions. It says: no source was supplied, so I did not invent a club. There is no tactical data, so I did not invent a formation. No player was named, so I did not attach a human being's career to a line of gossip.

I have sat in meetings where a piece was judged weak purely because it lacked a clear concluding line. Nobody objected to the data. Nobody questioned the source. They only asked: so what is your point. That is a fair question. But sometimes the most honest answer is: my point is that I do not know yet, and I have reasons for not knowing.

In a sports market where thousands of articles are produced every day, the scarcest thing is not information. The scarcest thing is refusal.

It took me three months to believe I was right, and two years to understand that being right is never enough. Those three months were spent rechecking a table of offside calls across four K League 2 matches, confident enough to defend it in front of an editor. The two years that followed were spent realising I had measured one thing correctly and forgotten ten others — defender positions, ball speed, the instant the pass left the foot. The table was not wrong. The way I read it was the thing that needed fixing.

The position of the writer who is wrong is not taught in any journalism class. It is still the most common position in the trade. The issue is how the wrongness is made public. A newsroom that lets a writer place a correction line at the end of a piece, with no self-defence attached, is stronger than any newsroom that never has to correct anything. Only something permitted to be wrong dares to check itself.

What is worth tracking next

Sports data is expanding faster than the public's capacity to verify it. A significant share of that infrastructure is fed by the demands of the betting market. Live data flows from match-tracking systems to bookmakers faster than any regulator can react. When information becomes a commodity, the question of verification stops being academic. It becomes a question of who holds the right to define the truth of a football match.

I have no ready conclusion for that part. I only have one method, accumulated across fifteen years standing outside the touchline and reading frames back: count first, write second. If you have not counted yet, write that you have not counted yet. An analysis without a conclusion is still an analysis. An analysis with a conclusion and no evidence is only an echo.

And in a transfer window full of echo, the reader deserves at least one thing that does not echo: a blank space marked honestly.
