When Analysis Has No Data: A Wake-Up Call for Vietnamese Sports?

In a quiet morning in Nha Trang, I opened an email and received a document titled Comprehensive Assessment. The document was long, but its content was strangely empty. Each section, each number, each conclusion was marked N/A — insufficient information. A thorough analysis full of risk warnings, but without a single event, name, or specific number. Perhaps it was a product of artificial intelligence assigned to analyze a non-existent article? Or a technical error? But for me, a person who has been involved in Vietnamese sports for decades, this document evokes a familiar reality: the serious lack of data in our country's sports. Let's face it. While countries like Japan, South Korea, or even Thailand build massive sports data systems with thousands of metrics on fitness, tactics, psychology, Vietnamese sports still operate on the experience of coaches. Players are transferred based on market value labels, but few verify real performance. National teams sometimes choose players based on old achievements rather than current form. The empty document I received is a perfect metaphor for data usage in Vietnamese football: the surface seems complete, but inside they lack core information. For example, in the recent transfer of a famous player from Club A to Club B, the press posted round numbers. But have we ever seen details of the contract structure: actual transfer fee, salary, bonuses, penalty clauses? How many contracts are audited by independent bodies? This lack of transparency makes sports analysts like us always work with half-truths. Moreover, in refereeing, VAR has been applied in a number of tournaments. But data on VAR's effectiveness, on the number of correct/incorrect interventions, on average waiting time... is not widely published. We only see endless controversies on social media. I recall my memory of 2026, when I discovered a forgotten talent in 400m running named Nguyen Van Hai. The boy ran 47.80 in a grassroots tournament, but there was no data about him in the national selection system. That performance was so good that in developed countries, he would have been recruited directly into a youth training center. But in Vietnam, he was just an unknown number. It took me two months following him, recording every practice session on the beach, every modest meal, to create a documentary compelling enough to convince a sponsor. Hai's story is the story of thousands of other potential athletes being abandoned due to lack of systematic data. If we had a national database of competition results, physical indicators, and training history of every athlete from provincial level upward, no one would be forgotten like Hai. But there is a paradox: Vietnamese people are very good at observing but very weak at recording. We are good at remembering players' faces, but forget how to record achievements. Youth football training centers often lack quantitative curricula and do not track player development by year. Coaches rely on their eyeballing but the eyes can be wrong. Contrarily, I have witnessed how the Japanese organize a youth football tournament. Each match, each goal, each pass is meticulously recorded. That data goes into the national system, and over the years, it creates a talent map. That is why Japan always produces top Asian players continuously. One of the reasons for the data shortage is the fear of disclosure psychology. Many sports organizations fear that publishing data will expose secrets, or reveal their weaknesses. But the truth is, once without common data, the harder it is to see accurately. Last year, when Vietnam's U23 team played in the AFC U23 qualifiers, the coach complained about lacking data on opponents' sprint speed to plan tactics. This is not just the national team's issue, but the whole football foundation. Could it be that our sports still develop in a movement manner, sometimes strong, sometimes weak, but difficult to predict? In my 2026 documentary Empty Stadium – Frozen Dreams, I asked a former track-and-field athlete why she was removed from the 2026 Olympic list. She only smiled sadly: Back then everything was handwritten, and papers were easily lost. No one monitored. The lack of data not only makes sports analysts like us struggle but also strips justice from the athletes themselves. From a broader perspective, in an era where sports betting is growing, the absence of independent data can easily lead to manipulation. Fans bet on rumors, not based on actual statistics. Bookmakers can take advantage of this. So where is the solution? Perhaps it is time for Vietnamese sports federations to start building an open, transparent, and cross-verified data system. The empty analysis document I received is a reminder that data is not just paperwork; it is the foundation for development strategy. We have made progress in facilities, but the data gap remains. Analysts like me and colleagues are willing to cooperate in training, building a standard sports data framework. But first, there must be direction and determination from management levels. Imagine if Vietnamese football clubs fully published data on players' playing time, tackling ability, pass accuracy rate... We journalists would not have to guess, fans would have a clear view, and scouts would easily find rough diamonds. Then the empty analysis will be a thing of the past. After all, we live in an era where data is king. If we do not embrace it quickly, Vietnamese sports will always wander in the dark, and there will be more forgotten Nguyen Van Hais. I hope not until Vietnamese sports documents are as dense as BBC Sport will we start acting. It is time for us to re-evaluate the value of data and transparency in sports. A sports foundation that wants to develop sustainably cannot rely on emotions or luck. Vietnam has many talents and many beautiful stories, but without data to preserve them, those stories will sink into oblivion like old VHS tapes in storage. I hope that in the near future, a Vietnamese sports analysis will be full of numbers, with every move and every step being recorded. That not only helps experts have a basis for decision-making but also helps fans understand more deeply about the sport they love. And then, articles like this will no longer need to sound the alarm.
