N/A Is Not the Final Answer: Vietnamese Football Lacks a Data System, Not Writers

On Saturday night, in front of my computer screen, I opened a report sent by the editorial team. Seventy minutes later, the only thing left was the same three letters: N/A. All nine sections, from tactics and finance to media risk, returned the same message: insufficient information. No xG, no PPDA, no market value, no positional map of the referee. It felt like a press conference where every question was answered by silence. Before talking about referees or transfers, I want to talk about something invisible. The report did not fail because the writer was weak. It failed because the whole football system runs on an old map: full of street names, but no traffic density. A system rarely collapses because of one individual's mistake. It collapses because of the silence of those responsible for holding the scale. From my years watching domestic football, the biggest limit is not professional judgment. It is the habit of judging matches through three basic numbers: possession, shots and cards. These numbers tell you which team dominated, but not why the dominant team lost. Without xG, without pressing data, without the referee's position, every tactical comment is merely beautiful noise. The same thing happens in transfer windows. A transfer window is like a court hearing, where every fee must be challenged with signatures and dates. But without the original contract, without release clauses, without the wage bill structure, a blockbuster rumor remains a floating story. When a transfer fails, people blame the player or the agent. Few ask how the scouting system collected data before signing. Disciplinary cases are even worse. Mistakes are not in the referee's eyes, but in the place he chooses to look. I need to see the referee's position, head movement, viewing angle and reaction time. If I only know the final result, the red card or the disallowed goal, I cannot judge whether the process was fair. When there is no complete VAR angle, the professional answer is: not enough evidence. Fans hate that answer. They want a name to blame. But an analyst has no right to punish, and should never turn into a court. I have a duty to see what the referee tries not to see. If there is not enough proof, I must be brave enough to say that I still do not know. Accepting uncertainty is a part of process discipline, not a sign of cowardice. At the macro level, the N/A story carries a clear signal: Vietnamese football does not lack passion or talent. It lacks an intermediate layer of data. Clubs can publish line-ups and results, but they do not publish pressing numbers, progressive passes, or dangerous turnovers. The locker room exists, tactics exist, but the numbers that verify tactics stay hidden in private reports. During transfer season, this gap is easy to exploit. A rumor without a source can become a hot topic for three hours. An inflated transfer fee can put pressure on a player. Without source credibility tiers, every successful or collapsed transfer is viewed through emotion. We need a data revolution starting from the pitch. It does not require a perfect Vietnamese version of xG. Just publish raw data. Standardize match reports. Allow journalists to access match events in a controlled way. Then those N/A reports will gradually disappear. Until then, the most professional attitude is to admit our limits. I remember the empty stadiums during the pandemic, where no one heard the whistle because there was no crowd. But even when applause disappears, the voice of the rules remains on the empty pitch. Data is the same. It does not need an audience, but it needs honest readers. A report that returns N/A does not mean the match is worthless. It means the picture is not clear enough. Before judging a referee, check the camera map. Before calling a signing a disaster, check the signature date and clauses. Before turning a defeat into a dismissal, ask whether the coach received enough supporting data. Vietnamese football is at a turning point. Youth teams are winning, clubs are spending more, and sports media is growing fast. But if we do not build an open data system, success will remain random sparks. Nobody will see the full picture, and every word of praise or criticism will be written on sand. It is time for football people to look at an N/A screen and understand that it is an invitation to gather better data. Start with youth matches, training centers and disciplinary analysis rooms. Every decision needs a process, every process needs a trace, and every trace should be recorded. Only then will N/A become a starting point for investigation, not the final answer. That is how Vietnamese football moves forward sustainably.
