Vietnamese Volleyball and the Notebook Nobody Keeps

The match ended at 9:40 p.m. The scoreboard still showed 3-1, and in my phone were four screenshots — none of them contained a statistic. I reopened the tournament's official page and clicked on the statistics section. There was no such section. Only the score, the two team names, the start time. An international women's volleyball match lasting nearly two hours, more than one hundred and fifty rallies, and the only thing left behind was a tiny row of numbers in the corner of a screen.

I stayed alone in the seventh row, behind me a group of supporters rolling up their banners. None of them knew that the home team's star attacker had just scored twenty-three points on an attack efficiency below thirty percent — meaning that for every three spikes, only one produced a point. That number tells a very different story from the "she played well" feeling in the crowd's heads. But it exists nowhere except in my head.

I am writing these lines after seventeen years spent at the edge of arenas, and the sense of loss still feels new. At twenty-four, I mispronounced a player's name three times during a live broadcast of a World Cup qualifier. I heard viewers call in to complain, I blushed and stared at the desk, I rushed into the archive room at midnight to trace every syllable. A name mispronounced three times is still a true story, if you are willing to listen carefully. From that mistake I built myself a pronunciation notebook, and later a rule: anything involving people must be written down before it disappears.

So when a volleyball tournament ends and leaves nothing but a scoreline, I feel something is being lost.

Vietnamese women's volleyball is in its best stretch in decades. The national team under head coach Nguyen Tuan Kiet has secured continental-level berths, reached medal matches in the regional arena, and currently sits in the world's top thirty to forty teams according to the International Volleyball Federation ranking. Names such as Tran Thi Thanh Thuy, Nguyen Thi Bich Tuyen and Le Thanh Thuy have gone abroad to play, bringing back experience and an entirely different way of seeing the job.

SEA V.League, the annual Southeast Asian men's and women's tournament organized by the Southeast Asian Volleyball Association, has become a familiar regional yardstick. At club level, LPBank Ninh Binh, VTV Binh Dien Long An, Bo Tu Lenh Thong Tin and Geleximco Thai Binh are used to international outings, foreign signings and fixed-term contracts. The national championship is televised, has major sponsors, has spectators buying tickets.

And yet one thing has stood still: the way we record what actually happened on the court.

In elite volleyball, a single match generates thousands of data points. At the Volleyball Nations League, organizers publish almost everything: perfect pass rate, attack efficiency broken down by position, blocks per set, aces against service errors, successful digs. That is what allows a coach to know precisely which rotation his team is stuck in, which attacker is being read, which block is out of sync.

In Vietnam, most of that data exists in another form: the notebook of an assistant coach. In the season I followed a local women's team to make a documentary, I sat directly behind the technical bench. The assistant coach wrote in pencil, one stroke per rally, one cluster per set. Halfway through the third set he turned and asked whether I remembered the twelfth rally of the second set. I reopened the footage I had just shot, counted, and read out the number. He kept writing.

That notebook carried the value of an entire analytics department. It showed which libero was passing better, which middle blocker was stuck in rotation two, and which substitute had entered exactly seven times all season without once having her name printed in a match report.

But where did that notebook end up? Three months later I returned to the club and asked for a photocopy. Nobody kept it.

Vietnamese volleyball does not lack record-keepers; it lacks a place for those records to keep living.

That sounds small, but the consequences are not. Without archived data, every personnel decision rests on collective memory. A new coach evaluates players on two weeks of training, on the word of the previous assistant, on instinct. A young player who performs well in youth tournaments is never called up to the senior side, because nobody has a number to compare her with the incumbent. A foreign signing plays brilliantly in her first season and declines in the second, and nobody can explain why, because there is nothing to look up.

In the region's stronger volleyball nations, the story is different. Japan publishes individual statistics from its domestic league. South Korea maintains season-by-season player data, enough for reporters to write analytical pieces about an attacker's decline. Thailand keeps national team records across multiple cycles, so it knows exactly who can replace whom. None of this requires expensive technology. It requires a decision: to treat data as an asset rather than scrap paper.

A volleyball match needs only about twenty basic indicators to reconstruct its entire story. The serving group covers direct aces, service errors and the rate at which serves break the opponent's reception system. The attacking group covers spike efficiency by position, and the split between in-system and out-of-system attacks. The blocking group covers blocks per set. The defensive group covers perfect pass rate and digs. That alone, recorded consistently, would produce a tactical map of a whole season.

For Vietnamese women's volleyball, that map would answer questions nobody can currently answer with numbers. Why does the team lose rhythm in the third set so often? Is the block being pierced from the wing or through the middle? At what moment does the opponent read our serving pattern? Without data, those questions can only be answered by feeling — and the winner's feeling is always right.

Now I have to say something few people in the profession want to hear.

There are two ways to look at Vietnamese volleyball's data gap. The first, more popular one treats it as a deficiency to be filled by importing the entire international statistical apparatus: licence software, hire specialists, buy ball-tracking cameras. The second, and in my view the more correct one, treats it as a broken habit — and the first task is simply a notebook that gets kept.

There is a troubling paradox. Modern analytics was built to serve a tall, powerful, low-error style of play. It rewards heavy spikes and high blocks. If a small, fast team that lives on reception and combination play tries to force that entire system onto itself, the result may be strangling its own identity. Data is not neutral. It carries built-in assumptions about which kind of volleyball is correct.

Vietnamese volleyball needs numbers, but it needs a set of numbers chosen according to its own questions, not according to someone else's template.

And here the memory of a documentary filmmaker becomes useful. The summer the women's team dissolved, I learned that a team does not die on the court; it dies when nobody is left to tell its story. Likewise, a season does not die when the team loses. It dies when no trace remains to look up.

I still keep the old habit: every match I watch, I write it down by hand. Player names, jersey numbers, positions, nicknames, pronunciation. Later, when making films, I cross-check every name against its linguistic origin, because I once got it wrong three times in one evening and do not want to be wrong a fourth time.

For Vietnamese volleyball, the same task now waits at a larger scale. A database simple enough that a sports student could update it. A place that stores assistant coaches' notebooks when the season closes. A page publishing national championship statistics, enough for fans to argue with numbers rather than with volume. The empty bench spots in match reports will have names, and those names will come with figures attached.

A sports documentary is not there to answer who won, but to ask why people love the game so much. Volleyball is the same. Victory is a moment, but the notebook is what keeps that moment in place.
