When the Data Is Empty: The Disease of Vietnamese Martial Arts Analysis

In November 2026, I sat in a coffee shop on Lach Tray Street in Hai Phong, reading a 3,000-word analysis of a Vietnamese fighter preparing for an international MMA event. The piece was thick with beautiful adjectives: "steel will", "warrior spirit", "a heart that does not know surrender". I read it from start to finish, folded it up, and realized something frightening: there was not a single number.

Not one SLpM figure — significant strikes landed per minute. Not one takedown defense rate. Not one comparison table with the opponent. Only emotion, carefully packaged, and a blind faith that fans would not notice the void in the middle.

I am not standing outside this story to judge it. In 2026, when I was 19 and a journalism student in Hanoi, I wrote a 2,000-word piece titled "Ronaldo Died Tactically". I was right emotionally, but empty on data. That night I learned my first lesson: emotion sells an article, but only data keeps your credibility.

Vietnamese football has Opta, has Wyscout, has stat tables detailed down to every pass, every pressing action, every metre run. Vietnamese martial arts has no equivalent.

Try to find a reliable database on Vietnamese fighters. You will find foreign websites with a few lines on records, a few wins and losses. But you will not find technical metrics, you will not find tactical analysis, you will not find anything that could be used to predict scientifically.

I remember once rewatching a Vietnamese fighter's bout at an international event. After each round, the commentator talked about "will", about "spirit", about "the hunger to win". No one mentioned how many times the fighter had exposed his flank, or by what percentage his accuracy dropped after the second round. I asked myself: if no one is counting, how do we know what we are watching?

What is the result? When a Vietnamese fighter steps into the octagon or the boxing ring, fans can only read about hometowns, about journeys, about tears. They do not know how many strikes that fighter throws per minute, what the accuracy rate is, or how he defends against takedowns.

This is not the fans' fault. It is the fault of a system that refuses to build a data foundation. And when the system is empty, analysis becomes a fantasy painted over with words. I got EURO 2026 wrong, not because I lacked information, but because I trusted the crowd — and I see that same mistake repeating in how we talk about martial arts.

In professional combat-sports analysis, there are eight dimensions that must be examined to produce a credible assessment. It took me years to realize this — not from books, but from wrong predictions and articles torn apart by readers.

The first dimension, and the foundation, is technical-tactical analysis. How many strikes does a fighter throw per minute? What is the accuracy rate of those strikes? How does he defend against takedowns? These questions have clear answers in any professional combat sport — but in Vietnam, they are routinely ignored. People talk about "fighting instinct" instead of "a 78% takedown defense rate". Nguyen Tran Duy Nhat may be the greatest Muay Thai fighter in Vietnamese history, but if you ask me what percentage of his wins came by knockout, I would have to open Google — and even Google cannot answer.

Truong Dinh Hoang once held the WBO Asia Pacific belt — a proud achievement. But if you want to know how he won those fights, you would have to rewatch the video and count for yourself.

The second dimension is physical condition and career longevity. A 32-year-old fighter with 15 years at the elite level carries a completely different injury risk from a 24-year-old. But in Vietnamese writing, age is usually mentioned only as a biographical detail, not as an analytical variable. I once read a piece praising a 35-year-old fighter as "at the peak of his form" without a single piece of evidence about reflex speed or recovery capacity.

The third dimension is event and organizational context. A fight in a major league carries pressure entirely different from a fight in a regional event. Contracts, clauses, schedules — all of them affect outcomes. But rarely do we see these factors analysed seriously. When a Vietnamese fighter signs with an international promotion, we celebrate — but we do not ask about the terms, the number of guaranteed bouts, the pay. Without transparency, there is no analysis.

The fourth dimension is the business model and the market. Professional combat sports is a business. How much is a fighter paid? Where does event revenue come from? These questions may sound alien to the pure fan, but they decide who fights, who gets promoted, and who gets pushed aside. I believe the truly valuable contracts lie with the small teams, the small promotions — where a young fighter can be developed properly. But no one discloses the financial structure of those events.

The fifth dimension is rules and compliance. Does a fighter follow doping-testing protocols? Has he missed weight? Does he have a history of sanctions? This is basic information any professional analyst needs — but it is often hidden or simply not collected.

The sixth dimension is health and career risk. Brain injury, weight-cut danger, psychological safety — these are life-and-death issues. I once wrote that demanding a fighter "prove himself" immediately after returning from injury is cruel, because it increases the risk of re-injury. But I realized that even such pieces lack data: we do not know how many injuries that fighter has suffered, how severe they were, or how the recovery went.

The seventh dimension is public narrative and market expectation. This is where Vietnamese journalism is strongest — and also most dangerous. We are good at creating moving stories, dramatic confrontations. But when the story runs far beyond the data, we create false expectations. I have watched this too many times: a fighter hyped by the media, then defeated, then abandoned by the very people who hyped him.

The eighth dimension is industry transmission. A combat-sports event affects not only fighters and fans. It affects gyms, broadcasters, sponsors, and even sports policy. When there is no data, these effects cannot be measured, and therefore cannot be improved.

Eight dimensions. Not one of them has enough data in Vietnam for serious analysis. And this is the crux: when the data is empty, analysis is not analysis — it is fantasy dressed in professional clothing. To understand a fight, I must look at the defeat before the fight — but in Vietnam, we do not even have data on that defeat.

But wait — where might I be wrong?

There is a counter-argument worth considering: perhaps Vietnamese martial arts does not need detailed data like international MMA. Perhaps Vietnamese fans come to martial arts for emotion, for stories, for people — not for stat tables. If so, imposing a dry data-analysis system could be a cultural mistake.

I weighed this argument for a long time. And I admit: it is partly right. Emotion is the soul of sport. Without emotion, sport is just numbers moving on a screen. Morocco in 2026 did not reach the World Cup semi-finals because they had the best pressing metrics — they reached the semi-finals because they had something that made the whole world stand up.

But here is the difference: Morocco had data. They had 212 presses within the first 5 seconds of losing the ball — a number I counted myself when analysing their matches. Morocco's defensive data was a revolution, and I chose to stand on the side of the revolution. Emotion and data do not exclude each other. They complement each other. Emotion without data is superstition. Data without emotion is machinery.

The problem with Vietnamese martial arts is not that we have too much emotion. The problem is that we do not have enough data for emotion to have a foundation. People call me a contrarian; I call it the way I keep myself sane — but even a contrarian needs a footing. That footing is data.

So what will change?

I do not believe in grand solutions. I believe in small, specific actions. Start by making every martial-arts article contain at least one verifiable number. Start by having gyms record fighters' training data. Start by having fans demand more instead of settling for pre-packaged stories.

Data does not make martial arts cold. It makes the stories credible.

And if I am wrong about this — if Vietnamese martial arts truly does not need data — then I will be the first to write a correction. I did it once with EURO 2026. I am ready to do it again.
