Three Combat Families, Three Rulesets: Why MMA, Boxing and Sanda Need Separate Data

One evening at a martial arts gym in Hai Phong, I listened to two men argue about “Vietnam’s number one puncher.” One cited the competitive record of a sanda fighter who had just won a regional medal. The other countered with the knockout rate of a young MMA fighter. Neither gave ground. What stood out: both were right, but both were measuring with the rulers of two different worlds.

I tell this story because it repeats almost weekly in my inbox. Readers send me a spreadsheet and ask why one fighter is “weaker” than another, without specifying whether they are comparing a professional boxing bout with an MMA bout, or a wushu form with a sanda match. Those three do not share a frame of reference. Analyzing in the wrong frame is wrong from the root.

In twelve years of following combat sports, I have watched Vietnamese fans grow more passionate — and more confused. Domestic MMA events are sprouting, boxing gyms are opening across major cities, and Muay Thai and kickboxing clubs are drawing young people. Alongside them, wushu taolu remains a high-performance sport within the national competition system, while sanda is a combat discipline with its own rules. These four groups — MMA/boxing/kickboxing/Muay Thai/grappling (modern combat), wushu taolu (performance), and sanda (hybrid combat) — split into three entirely different analytical logics.

The problem is that the media, and some analysts too, are lumping them together. They treat “achievement” as a universal unit of measure. A sanda medal, a boxing title belt, a taolu score — all thrown onto the same scale. That scale does not exist.

Start with the frame of modern combat. MMA and boxing both score with the 10-Point Must System, but the weightings differ. Boxing allows punches with the fists only, so the key metrics are significant strikes landed per minute (SLpM), strikes absorbed per minute (SApM), and accuracy. MMA uses the Unified Rules — adopted by the state of New Jersey in 2026 and first applied at UFC 28 — permitting punches, kicks, takedowns and submissions. MMA metrics therefore must include takedown accuracy, control time, and finish rate.

This is where many people stumble. An MMA fighter with a high SLpM is not necessarily better than a boxer with a high SLpM, because the meaning of a punch differs between the two rulesets — in MMA, the punch is one of five tools; in boxing, it is the entire weapon. Comparing those two numbers without conversion is comparing metres with miles.

With wushu taolu, the logic flips entirely. Taolu has no opponent and no knockout. It is scored on difficulty and performance quality. A good taolu athlete has no “combat record” at all, and that does not make them inferior. Putting a form against a fight is confusing the discipline, not the person.

Sanda sits in the middle, and it is the hardest case. Sanda allows punches, kicks and throws — closer to MMA than boxing. But sanda rules differ in specifics: how points are scored for throws, how simultaneous exchanges are handled, and the protective gear. A sanda fighter moving to MMA must relearn stance, distance management, and most importantly how to take hits without padding. Those who watch one sanda match and then draw conclusions about MMA skip this entire transition.

In Vietnam, the story is even more tangled with Vovinam. This is the Vietnamese martial art, with both form (performance) and combat content, and its own belt system. A Vovinam combat champion and a Vovinam form medalist are two athletes in two entirely different achievement categories, even if they wear the same uniform colour. When the media calls both “Vovinam champion,” they inadvertently erase a boundary the discipline itself erected.

At the organizational level, the confusion is heavier still. Professional MMA runs on a league model with exclusive contracts, where a fighter signs with one organization and is largely barred from competing elsewhere. Boxing has a fragmented belt system: one weight class can have four champions from four different bodies. Wushu taolu is tied to the national competition system and multi-sport games, where achievement is measured in medals, not prize money. These three systems distribute opportunity in three incomparable ways. An MMA fighter cannot demand a slot at a taolu games, and a taolu athlete cannot earn a living from an exclusive contract.

There is one dimension every argument about achievement ignores: health. Boxing and MMA allow high-intensity strikes to the head, accumulating brain injury over time. Wushu taolu carries almost no collision risk. Sanda sits between, with protective gear that mitigates but does not eliminate injury. When we place a taolu medal beside a boxing belt, we are not only comparing two achievements — we are comparing two different levels of risk the athlete pays for.

I often use this example when explaining to newcomers. Imagine three teachers grading three different subjects: one grades combat, one grades martial dance, one grades grappling combat. If you hand one teacher’s student paper to another, the score is meaningless — not because the student is poor, but because the teacher is grading on the wrong scale. Vietnamese combat-sports media does exactly that every day, unconsciously.

Based on my experience watching matches, I always ask one question before analyzing: what is this bout scored by? If the answer is “10 points under MMA rules,” I open the combat metrics sheet. If it is “difficulty under taolu rules,” I open the performance scoring sheet. No single sheet works for both.

But here I have to slap myself. Ronaldo’s tears back then taught me that: even legends know pain. A belief is spreading through the analysis community: that with enough data, we will predict outcomes correctly. I once believed it. I got EURO 2026 wrong not for lack of information, but for trusting the crowd. That lesson stings harder in combat sports, because combat sports carry a variable no spreadsheet ever captures: the moment.

A fighter can win every metric and then fall in three seconds. A punch that was never in the plan can change an entire career. We build ever more sophisticated models only to forget that a human being is not an equation. The reverse trap is not meant to oppose the player, but to oppose prejudice — including the analyst’s own.

What does that mean for a writer like me? It means I must present data as an argument, not a verdict. And it means I must state my own limits before speaking of a fighter’s limits.

This does not mean comparison is impossible. We can still compare two fighters under the same ruleset, the same weight class, the same era. But comparison only means something when variables are controlled. Combat sports have never been a single variable, and the best writing is the kind that admits this from the very first sentence.

What I want to see in the coming year is not another spreadsheet, but a convention: whenever two fighters are compared, the writer must state which rules and which frame of reference are in use. If that happens, the “number one puncher” argument will be less loud and less wrong. And if you still want to compare a sanda medal with a boxing belt, try one small thing first: ask what unit that scale measures in.
