When the Fight Data Sheet Is Empty: Eight Analytical Dimensions and a Writer's Most Expensive Mistake

The Empty Column in Manila

On December 11, 2026, in Manila, a 21-year-old Chinese fighter named Yang Jian Bing collapsed in his hotel room a few hours before the weigh-in for ONE Championship: Spirit of Champions. He was taken to hospital and did not survive. The announced cause was cardiorespiratory failure, following a water cut to make flyweight.

Years later, opening the file on that night again, what stopped me was not the number on the scale. It was an empty column. In the promotion's forms that year, the field for "urine specific gravity test" did not exist. Nobody measured. Nobody recorded. A fighter died from a metric that had never been given a name on paper.

ONE Championship later rebuilt its entire weigh-in process around urine specific gravity, and maintains it to this day. That is a technical change, and read aloud it sounds dry. To me it is the biggest lesson of my career: a blank cell in a data sheet is not empty space. It is where the truth sits.

Between two rounds, there is a silence that holds the whole truth.

Two Analytical Frameworks and the Death of an Article

There is a question almost nobody in the trade asks before sitting down to write: which kind of martial art is this article about? It sounds like a formality, but it decides the entire logic of the piece.

An MMA bout is read through win rate, finish rate, and quality of opposition. Professional boxing is much the same, differing only in the scoring system and the number of rounds. But an article about wushu taolu cannot be read through win rate, because in taolu there is no opponent to beat. Scores are built from difficulty of movement, precision, stability, and a panel of judges seated at three corners of the mat. Sanda is different again: there is contact and there is scoring, but the emphasis falls on accuracy of strikes and number of takedowns.

If I use win-loss logic to write about a taolu routine, I produce an analysis that is wrong at the foundation. Not wrong in the details, but wrong in its frame of reference. That kind of error cannot be fixed by adding more data. You have to pull it apart and start again.

This is why I always begin by identifying the discipline and the ruleset. Wushu has been added to the programme of the Dakar 2026 Youth Olympic Games. That event will produce an entirely new class of athlete, trained to international competition standards rather than traditional performance standards. If someone calls me tomorrow and says "write about the generation of Vietnamese wushu athletes preparing for Dakar 2026," I must already know that I am writing about a scored discipline, not a combat discipline.

Same result, yet insiders and outsiders are watching two different contests.

Dimension One: Technique and Tactics

At the first layer of analysis I need four things: the style matchup, finishing ability, quality of record, and key metrics. Sounds simple. But quality of record is where deception is easiest.

An MMA fighter with a 15-0 record and one with a 15-7 record are not in the same class. But a 12-0 fighter who has only beaten newcomers is no better than an 8-4 fighter who has shared a cage with former champions. I once spent three weeks cross-referencing two such record sheets, and the final conclusion was that a record sheet says nothing without quality of opposition attached.

This is why Naoya Inoue is a case worth studying. He unified four bantamweight belts in 2026, then unified four super bantamweight belts in December 2026 after beating Marlon Tapales. The notable part is not that he holds four belts. It is that he beat men who had held belts, not men who had never touched one. That is where quality of record lives.

Terence Crawford is the mirror-image case in terms of how we read it. He unified four super lightweight belts in 2026, then unified four welterweight belts on July 29, 2026, after beating Errol Spence Jr. Look at the record and you see an unbeaten run. Look at the quality of opposition and you see a run in which nearly every opponent had been a champion in his own division.

At the purely tactical layer, the matchup is the thing a statistics sheet can never capture. A strong grappler against a strong range-keeper produces a fight in which both men lose statistically. Strike counts drop on both sides, takedown conversions drop, and viewers call it a dull fight. Inside the gym, it was the most carefully prepared fight of the year.

People look for the goal; I look for the forgotten pass. In combat sports, that forgotten pass is the rhythm of the lead foot before a strike is thrown. Nobody records it. And precisely because nobody records it, it becomes the most valuable data there is.

Dimension Two: Physical Condition and Career Longevity

The four columns I always check at this layer are the age curve, weight-cut risk, injury wear, and camp quality.

Age curves in combat sports do not work like football. A 34-year-old lightweight may still be at his peak, while a 34-year-old heavyweight may have five more years in him, because heavyweight does not demand the same reflex speed as lightweight. Conversely, a 28-year-old with twelve professional years behind him may already be in early decline compared with a 33-year-old who only turned professional four years ago.

Weight-cut risk is the column I rank highest, because this column kills people. Yang Jian Bing is the landmark case. But he is not the only case, and he is not the last. Many small promotions across Asia still permit fighters to shed eight to ten percent of body mass in 24 hours, then rehydrate within hours before stepping onto the mat. The human body was not designed for that.

Camp quality is the final column, and the least assessed. A fighter with a coach who competed at the top level prepares in a fundamentally different way. Not because the drills differ, but because that coach knows when to stop. Young fighters usually do not know the stopping point. An old teacher is the person who knows it for them.

Dimension Three: The Organisational and Event Landscape

Here I must draw a hierarchy chart before writing a single word. Who is the owner, who signs exclusive contracts, who distributes.

Combat sports today has four tiers of differing exclusivity. The first tier is the UFC, where exclusive contracts are near-absolute. The second is the PFL, which after completing its acquisition of Bellator in November 2026 became the number two force in the North American market. The third is ONE Championship, strong in Asia but operating on different logic: staging events across many countries, distributing across many platforms, and keeping a large roster of local fighters. The fourth tier is regional promotions such as RIZIN in Japan, or the Thai boxing circuits at Lumpinee and Rajadamnern stadiums.

In boxing, the fragmentation sits at the title layer rather than the organisational layer. Four sanctioning bodies issue belts: the WBC, WBA, IBF and WBO. An undisputed champion must hold all four. This creates a barrier unrelated to ability: a barrier of scheduling. Two excellent fighters can lose two years simply arranging one bout.

And cross-promotional fights always carry a question about motive. On October 28, 2026, Tyson Fury met Francis Ngannou in Riyadh. Fury won by split decision. On March 8, 2026, Anthony Joshua stopped Ngannou in the second round, also in Riyadh. Same opponent, two entirely different outcomes. That tells me that in those two fights, what was being measured was not Ngannou's level, but the seriousness of preparation on each side.

On May 18, 2026, Oleksandr Usyk beat Fury by split decision to unify four heavyweight belts. In the rematch on December 21, 2026, Usyk won by unanimous decision. Two fights, and both times Fury lost in the late rounds. Same fighter, same opponent, and the same weakness repeating itself.

I am old now, but my count is still twenty years old. And that count tells me the most attractive cross-promotional fights are usually not the best ones.

Dimension Four: Business Model and Market

This is the dimension I write most slowly, because every number here can be misused.

The four revenue lines that must be separated are: pay-per-view and broadcast rights, gate and live events, fighter pay, and sponsorship.

One citable fact: in September 2026, the UFC reached a settlement of USD 375 million in the antitrust case brought by a class of plaintiffs led by Cung Le against Zuffa. That figure is not just a sum of money. It is an acknowledgement that the industry's pay structure has a legal problem, not merely an ethical one.

A second fact: on August 11, 2026, Paramount announced an agreement to bring the UFC to Paramount+ in the United States from 2026, reported at roughly USD 7.7 billion over seven years. That number shows the value of combat sports rights has outgrown the sports frame and entered the mass-entertainment frame.

Set against each other, those two figures reveal a paradox. Money into the industry is rising, yet the share paid to fighters at major promotions still hovers around 16 to 20 percent of revenue, while major American team sports pay their athletes roughly 50 percent. Nobody wants to say this out loud.

Transfers are where value gets replaced by price, and nobody dares say it. In combat sports, transfers do not happen by season. They happen through exclusive contracts, and an exclusive contract does not tell you a fighter's true value, only the price an organisation is willing to pay to keep him.

Dimension Five: Rules and Governance Compliance

The four items to check here are judging and scoring, doping-test compliance, weigh-ins and weight classes, and disciplinary measures.

The Unified Rules of MMA date from 2026 and still use the ten-point must system. But that system has a gap: it cannot distinguish a narrow round win from a dominant one, because both can be scored 10-9. The consequence is that fights in which all three judges score correctly can still produce a controversial result.

On doping, the UFC ended its partnership with USADA on December 31, 2026, and moved to a new provider from 2026. That is a governance change, not a technical one. But it directly affects how records are read: when the testing system changes, every comparison between records before and after that line becomes fragile.

On eligibility, Paris 2026 is an example of how the rules do not sit in one organisation's hands. Imane Khelif won gold in the women's welterweight division on August 9, 2026, and Lin Yu-ting won gold in the women's featherweight division on August 10, 2026. Both had been removed from the 2026 world championships run by a different federation, yet were cleared to compete in Paris by the International Olympic Committee. Two governance systems, two opposite conclusions, one athlete in each case.

Dimension Six: Health and Career Risk

This is the dimension I never write as a summary, because every conclusion here has someone paying the price for it.

The six risk groups to track are: brain health, weight-cut incidents, injury, post-retirement security, psychological safety, and systemic risk.

The first group is the heaviest. The CTE research centre at Boston University has documented cases of repetitive head-impact disease in the donated brains of boxers and MMA fighters. What stands out is that these cases did not come only from knockout losses. They came from cumulative impacts across an entire career.

The second group is the one I mentioned at the start. Death from weight cutting is a category of risk that can be reduced to almost zero if a promotion is willing to measure. But measuring costs money, costs time, and can cancel a fight at the last minute.

One thing I must state plainly: the silence of the data in this dimension does not mean the risk is absent. It only means nobody has measured it yet.

Dimension Seven: Public Narrative and Market Expectation

The three indicators I track here are: how much the record underpins the story, the quality-of-opposition test, and the expected durability of the narrative.

Every rising fighter passes through the same cycle. First the hype phase. Then the verification phase. Finally the revaluation phase. The distance between the first and the third is the gap between expectation and reality.

At this layer I separate two kinds of story. The first is built from results, and it has a long lifespan. The second is built from talk, and its lifespan equals exactly the interval between two press conferences.

A catchweight or crossover bout is the textbook example of the second kind. The competitive gap between the two sides is usually enormous, and both sides know it before signing. One side's motive is money. The other side's motive is money. Only the audience believes in something else.

Fake news does not die because people stop believing it; it dies because people stop verifying it.

Dimension Eight: Industry Transmission

I draw this diagram in three tiers: upstream is gyms and the talent pipeline, midstream is organisations and events, downstream is broadcast, betting, and consumer markets.

Upstream, camp quality determines fighter quality five to seven years later. This is the slowest tier, and the least invested in.

Midstream, organisations control the schedule, and the schedule controls opportunity. A talented fighter with no slot to compete is no different from a fighter without talent.

Downstream, betting data has become an information source with as much force as the media. I never use it to predict, but I always use it to cross-check. When the odds and the technical reading diverge, one of the two sides is usually short of information.

Vietnam occupies a particular position in this diagram. Nguyen Tran Duy Nhat and Tran Quang Khai have competed in ONE Championship, bringing in a significant audience and creating a new layer of gyms in Ho Chi Minh City and Hanoi. Nguyen Thi Tam and Nguyen Van Duong represented Vietnamese boxing at the Tokyo 2026 Olympics. Vovinam, founded by Nguyen Loc in 2026, has featured at the SEA Games since 2026 and is producing a young class of athletes trained to international competition standards.

But the transmission line from gym to broadcast in Vietnam remains very thin. There are fighters, there are gyms, there is an audience, and the connector in the middle is missing.

An Empty Space Is Not Neutral

This is the section I must state most clearly, because it is the section I once got wrong.

When a data sheet is empty, there is a strong temptation to insert a neutral conclusion. No weight-cut data, so we write "the weight-cut issue has not been fully documented." No injury data, so we write "the fighter is in stable condition." Those sentences sound cautious, but they are in fact claims. And they are claims without evidence.

An empty space is not neutral. An empty space is unknown. Those two things are entirely different.

I believed the maths before I believed the pitch; that was my most expensive mistake. In 2026, before the World Cup semi-final between Croatia and England, I wrote a long piece asserting Croatia would lose on fitness: eight starters over 30, and three extra periods already played. Croatia won 2-1 with 58 percent possession. Afterwards I rewatched the entire match tape, logged 214 set-piece situations, and discovered something the statistics sheet never showed: Croatia deliberately slowed the game in extra time to conserve energy. The data I used was correct. The conclusion I drew was wrong. Because I had ignored a variable nobody had measured.

Since then, every prediction piece of mine must contain a dedicated section: the conditions under which I could be wrong. And I replace absolute assertions with evidenced questions.

In 2026, when the pandemic halted every competition, I stayed home and slid into anxiety. With no new matches, I dug through the archive of China national team tapes from 2026 to 2026 and found a pattern: when possession rose by more than 12 percent in the first half, the second-half loss rate was 71 percent, seven out of ten matches. The series of pieces on those numbers drew 60,000 reads, and a club in Chengdu approached me to act as an unofficial consultant.

But what I learned from that series was not how to find patterns. It was how to notice what I had left out. Seventy-one percent is a strong number. But it says nothing about the other three matches, and those three matches are where the truth sits.

Old files gather dust, but the curve of that punch from years ago is still there in the data. The problem is that we usually look at the end point of the curve, and never at where it began.

Signals to Track

Three signals I will follow in the period ahead.

The first is whether promotions publish complete weigh-in data. If a promotion publishes urine specific gravity both before and after the weigh-in, that is a signal it is moving from damage control to prevention. If it publishes only the scale number, that is the opposite signal.

The second is how national wushu federations prepare for Dakar 2026. This is the first time a traditional martial art enters the youth Olympic system. How they select athletes, how they score internally, will show whether they are moving toward sportification or holding to performance.

The third is the revenue share paid to fighters at major promotions. That number has stood still for too long while rights fees have soared. A change here would pull every other tier with it.

I do not know the answers to any of these three signals. But I know I will not fill the blank with a neutral sentence again. If I do not know, I will write that I do not know. That is the only thing I can do after 38 years standing at the edge of the mat, listening to the count.
