Nine “insufficient data” warnings in a women’s table tennis analysis: a lesson for Vietnamese sports

On the evening of August 13, 2026, a colleague sent me a ten-page women’s table tennis analysis. Every page had a professional evaluation framework, but every conclusion repeated the same phrase: “Not enough information to assess.” Nine analytical sections, and none of them could stand on data. Having spent three decades in sports media, I did not treat this as a failure. I treated it as a signal. In 2026, when Hang Day Stadium was empty because of the pandemic, I once stood in front of an empty stand and said: “When the pitch is at its quietest, I can hear the voices of those who never had a seat on the broadcast.” That evening, the silence I heard was data. The analysis contained all the headings of a modern sports research report: technique, tactics, player profiles, competition system, competitive landscape, coaching staff, risk, media narrative and the wider industry ecosystem. It was a rigid analytical grid. But underneath the grid, every box was empty. There was no athlete name, no score, no serve count, no head-to-head record. That reminded me of the 2026 World Cup in Russia. When I asked a female fan outside the Luzhniki Stadium, I realized I was asking through a layer of prejudice. I changed my approach and listened to her story before discussing tactics. The 2026 World Cup taught me that prejudice is powerful only when we believe it is true. An empty analysis, if read the wrong way, can also create prejudice: the prejudice that women’s table tennis lacks data, lacks expertise and lacks credibility. I do not believe that. The problem is not the sport. The problem is how we collect and publish information. Based on my experience following women’s table tennis matches, I have learned that a beautiful loop is less valuable than a statistic with a clear source. On the table, there are rallies lasting twelve shots but never recorded. If we only watch highlights, we cannot see a player’s real stamina. If we only read the result, we miss how she turned the match around in the third game. When digital media began rolling, the 4-4-2 formation also learned to step off the page. To do that, we first need reliable data; slogans cannot replace a match report. The current transfer period is very noisy. On social media, every young player who plays one good match immediately becomes the target of a big club. A fabricated signature becomes a detailed deal. A fabricated salary becomes an exact number. In that context, a report that clearly says “not enough information” is the opposite of a rumor. It is not attractive, not shocking, and not built for clicks. But it is honest. And honesty is what a transfer window needs most. I listen to players before I discuss tactics, because the heart always comes before the formation. That heart must be protected by verifiable numbers, not by anonymous gossip. In the technical analysis section of the report, there was no information about grip style, spin trajectory, service point-win rate, or the ability to transition from defense to attack. There was no rally rhythm, no physical fluctuation after the third game. If a coach read that report, he could not design a training session. If a reporter read it, he could not write a story. But if a bookmaker read it, they might create a misleading betting line. That is when an empty data field becomes a danger. Sports betting and esports betting are growing faster than the rules around them. When the source of information is not verified, what gets distorted is not only the score but also the trust of fans. Some people will say that such an analysis should not be published at all. I disagree. To me, it is a transparency check. It shows that a group of analysts refused to write recklessly without evidence. That reflects professional ethics. The real problem is that many newsrooms are not brave enough to print the phrase “cannot assess”. They are afraid of an empty page, afraid of losing readers, afraid of losing the algorithm. But an honest page is worth more than a page full of guesses. I have been fiercely criticized when I wrote about a female athlete who did not win a medal. Hundreds of comments said I was defending weakness. I learned that criticism is also a form of recognition, as long as I stand on facts. Vietnamese women’s table tennis does not lack stories. The players have advanced at SEA Games, caused surprises in regional tournaments, and returned from injury. But each of those stories needs to be recorded through match notes, service statistics and head-to-head history. Without those, a story becomes a myth, and myths cannot be the basis of tactics. When media runs on emotion, writers are easily pulled into the whirlpool of praise and blame. I choose to write slowly. Every observation needs a source. Every number needs a context. Every gap needs to be called by its true name. When I closed the report, I did not feel disappointed. I saw a reminder of how to do sports journalism in an age of rumors: call a match a match, call a number a number, and call an empty space an empty space. Nine “not enough information” sections may make a broken article, but if it is read correctly, it becomes a lesson not to fill in blanks recklessly. Prejudice is powerful only when we believe it is true, and sport is trustworthy only when truth is recorded with data, not with instinct.
