Vietnamese Volleyball and the Empty Spreadsheet: A Growing Game Nobody Is Counting

On the night of August 14, after the fourth set of a national volleyball championship semifinal, I opened my laptop and did what I always do after a match: I tried to rebuild the game with numbers. I needed to know the winning team's perfect-pass rate, how they scored off the opponent's serve, which rotation was their breaking point. I typed into the first cell of the spreadsheet. Then the second. Then the twentieth. The spreadsheet returned a bottomless blank. No perfect-pass rate. No side-out rate. No blocks per set. Not a single number.

A semifinal had just been played in front of thousands in the stands and hundreds of thousands on screens. When the final whistle blew, the only thing left was memory. Memory is beautiful. But memory never answers the simplest question: why did that team lose. The majority is never wrong, but it also never writes history — and in Vietnamese volleyball, the majority is writing history out of memory, out of feeling, out of sentences like "she played so well today."

Vietnamese volleyball is living through its most fertile period in decades. The women's national team has left its mark on the Asian stage; domestic leagues sell more tickets; the VTV Cup has returned regularly and become a genuine international arena, no longer a stroll. Clubs are beginning to secure long-term sponsors. Names like Tran Thi Thanh Thuy, Nguyen Thi Bich Tuyen and Nguyen Thi Ngoc Hoa are mentioned in the media more than any generation before them.

But when I want to understand a match at depth — not who won, but why they won — I have nothing to hold on to. Vietnamese football, for all its shortcomings, has a reasonably stable data foundation: passes, shots, heat maps, the PPDA metric. Volleyball is nearly bare. There is no public database that lets an outsider like me verify a tactical claim. To say "this team is poor at serve reception," I have to count it myself — and I have counted, with my eyes, for years, but the human eye never counts as accurately as a machine.

At the great volleyball competitions of the world, people do not argue with feeling. They argue with perfect-pass rates, with each attacker's efficiency by position, with ace-to-error ratios. A coach in Italy or Turkey can look at a sheet of numbers and know instantly which rotation needs a substitution. In Vietnam, we still substitute on instinct.

I am not telling this story to complain. I am telling it because I have just seen a mirror image of myself inside a system failure.

In the world of sports-data analysis, there is a frightening term: pipeline failure. It is when a data-collection system runs its process correctly but the input is empty, and instead of raising an alarm it still emits a complete analytical framework: full headline, full sections, full formatting — missing exactly one thing, the truth. A reader skimming it takes it for serious analysis. In reality there is not one number inside.

Vietnamese volleyball is in the opposite situation but of the same nature: there is truth, there are matches, there are players, there are arguments — but the data pipeline is empty. We have enough raw ingredients to cook a good meal, but no pot.

So I set myself a small test. I took a match I remember clearly, one I believed I understood, and I tried to write down everything I "knew" about it. The result chilled me. Most of what I thought was analysis was really memory polished with words. I remember Team A won because of "character." I remember Player B shone in a "moment of genius." But if I must answer in which rotation Team A won, by what means, thanks to which coaching adjustment — I fall silent.

Now let me say what I believe is the core, and say it with the full bluntness of a man who has spent 36 years inside arenas.

Volleyball is a sport where the serve-reception system decides almost everything else. In football, one moment of individual genius can decide a whole match, and that is beautiful. In volleyball it cannot. Volleyball is a domino chain: a good first touch opens a good second touch, a good second touch opens a good third touch, and only the third touch is a point. Drop the first touch and the whole chain falls. No individual can rescue a ball that has ricocheted off the boundary, because the rules do not allow it.

And this is exactly where data should unleash its power — but in Vietnam it has not. When the national team walks into a match against a stronger opponent, the life-or-death question is not "who attacks best" but "which rotation are we stuck in." In volleyball each team has six rotations in serving order, determining who is at the front and who at the back. Usually a team has one or two structurally weak rotations, because there only two genuinely dangerous attackers are front-row instead of three. Professional opponents know this. They serve-break into the weakest receiver in the weak rotation, forcing you to attack out of system, and every rally becomes the lone battle of one player against an entire wall.

Based on my experience following matches, this is the pattern I see repeating in many Vietnamese volleyball teams: they win when the opponent serves gently, they collapse when the opponent serves viciously. Not because the attackers are poor. But because the first touch is not solid enough to open a second attacking option.

I can count that with my eyes, match after match. But I cannot prove it. And in an era when every statement is demanded to be backed by evidence, a reporter who cannot prove himself is nothing but a storyteller.

There is something I have not told you. In the summer of 2026, when 92 percent of viewers picked Brazil or France to win the World Cup, I declared Croatia would reach the final. I was right, and I was right not by luck. I was right because I had data on that midfield, on their six corner-kick patterns, on their fitness base. I saw Croatia before the world was willing to open its eyes, simply because I had numbers in hand. I want to do the same with Vietnamese volleyball. I want to tell the country that this team's third rotation is its fatal flaw, that a certain attacker will explode in the fourth set because the opponent has run out of gas. But I cannot, because I have no data. And that helplessness is an indictment — not of me, but of an entire system that has grown too used to not counting.

What is worth saying is that the technology to do this is not expensive. Score-tracking software by rally, a standardized spreadsheet, one person recording properly — that is all it takes. Professional volleyball leagues around the world have done this for decades, in volleyball nations no richer than Vietnam. Our problem is not a lack of money. It is a lack of awareness that those numbers have value.

Now comes the part I know will irritate many people.

I do not believe Vietnamese volleyball fails on the international stage because of a lack of talent. I believe the opposite: we have talent in abundance, and it is precisely that abundance that hides a deadly structural hole. When you always have one individual who can score in any situation, you will never feel enough pain to fix the system. An outstanding individual is a painkiller. It soothes the pain of a poor first touch, of a skewed rotation, of an inconsistent defensive scheme — and because it soothes, you never cure the root.

People often say a good volleyball team is one with many good attackers. I say the reverse: a good volleyball team is one with few bad attackers. At the Asian elite level, the gap between teams does not lie in the brightest star, but in the sixth and seventh players of the squad. The worst serve receiver on the court is the link that decides the fate of the whole collective.

And this is where I may be wrong.

There is another possibility, more beautiful and equally credible: that Vietnamese volleyball does not need data to rise. That instinct, improvisation, the ability to read a match by intuition — things born from thousands of hours inside arenas rather than from spreadsheets — are what distinguish a team with a soul from a machine. If I impose my foreign default on a young, growing volleyball culture, I may be committing exactly the mistake of those who once imposed the Brazilian default on Vietnam. If I demand that Vietnamese volleyball have a perfect-pass metric before it has learned to play beautifully, I may be killing the best thing about it.

The rebel is not afraid of being wrong, only of being like everyone else. But the greater fear is becoming a conservative in the costume of a pioneer.

It is also possible I am too impatient. Vietnamese women's volleyball has made real progress, and the national team has traded blows evenly with major volleyball nations. The results are there — they do not need me to defend them with data. I am demanding a higher level of civilization while I myself may not have done enough to lay its foundation. A man from Brazil sitting in Nha Trang teaching Vietnamese people how to count volleyball might sound absurd, if I did not remind myself that the outsider sometimes sees what the insider has grown too accustomed to notice.

I want to end where I began: with my empty spreadsheet. I will not fill it with guesswork. I will fill it with truth, one number at a time, if someone will sit and count. One person counting every match will give Vietnamese volleyball more than any commentary — including this one.

Fifty-two years old has taught me that a hot take is not recklessness, but daring to look one set further ahead. After 36 years observing the industry, I have learned one thing: sports do not die of losing. They die of being forgotten. Vietnamese volleyball has too much in it to be forgotten. But memory is a thin dike, and it will break before the next generation — unless we begin to count.

That is my message. Not to win an argument. But to open the right one.
