The Empty Spreadsheet: Vietnam Volleyball's Habit of Concluding Too Soon

1. A file with nothing but column headers

There is a spreadsheet on my computer that I have opened many times and never once typed a number into. The file is named VN_VOLLEY_RECEPTION. The first row has six cells: match date, team, rotation, perfect-pass rate, out-of-system attack rate, and points scored from the serve sequence. Six column headers, and beneath them a blank space running the length of the page.

I opened that file one night in the middle of the national championship season, after watching a match where the winning team was praised with three words — character — and the losing team explained with two — spirit. For two hours, nobody in the commentary box produced a single percentage. I went home, opened the file, placed the cursor in the first cell, and realised I had nothing to type.

Not because I watched carelessly. Not because I was lazy. The things I needed — touch sequences rally by rally, first-pass quality, the number of attacks forced when the ball moves outside the system — are not recorded anywhere in a form an outsider can look up. The arena scoreboard gives me points, kill blocks, direct aces. It does not tell me why those numbers look the way they do.

Every analysis I write begins with a forgotten number. Here, the forgotten number is one that does not exist.

2. A court without a detailed scoreboard

At 64, I have watched Vietnamese volleyball across enough generations to remember seasons when a single scoresheet sat on the referee's table. The stage is different now. The national championship runs in two phases, men and women playing in parallel across several arenas, with clubs such as Trang An Ninh Binh, Sanest Khanh Hoa and Bien Phong on the men's side and LPBank Ninh Binh, VTV Binh Dien Long An, VietinBank and Hoa Chat Duc Giang on the women's side forming an ecosystem thick enough to keep someone in my trade busy every week.

At national-team level, Vietnam's women appear regularly in regional and continental competition: SEA Games, SEA V.League, AVC Cup, and invitational events such as the VTV Cup. The men's side has the Hung Vuong Cup and SEA Games runs where a semifinal place is no longer a distant dream. Vietnamese players going abroad to play is no longer unusual news. Viewership, commentary volume and posting volume have multiplied against the era when I filed my first article.

But the data infrastructure has barely moved. A top-level Vietnamese volleyball match produces around two hundred rallies; each rally contains between three and seven touches, meaning more than a thousand encodable contact events. Of those, what is published publicly is usually: individual player points, kill blocks, direct aces, and sometimes attack efficiency as a rate of kills over attempts. Those four groups are enough for a news line. They are not enough to answer a tactical question.

Based on my experience tracking matches, this shortage is not because Vietnamese people are lazy record-keepers. Coaches keep records. Assistant analysts at many clubs keep records, sometimes in specialised software. The problem is that this data stops inside the technical meeting room. It does not go out, it is not standardised, it is not published under a shared convention. The result is that fans and writers are pushed back toward the only thing left to argue with: feeling.

And when feeling becomes the currency, the loudest wins, not the most correct.

3. The serve: where the match is actually written

From Russia 2026, I learned that the dead ball is the only thing that never dies.

That summer, at 56, I re-watched all 64 matches of the World Cup finals, freezing the frame on every dead-ball situation, and counted 73 of 169 goals — 43.2 percent — originating from a set piece. England scored nine that way, more than any other side. Croatia used four fixed patterns, each with three to five variants. I cross-checked against the V-League spreadsheet I had built for 2026 and found a gap in set-up efficiency of 28 percent.

That number haunted me for a long time. Only when I moved into volleyball did I understand what it means here.

In volleyball, the serve is the only dead-ball situation in the entire match. The ball sits still on the hand, the clock starts, and all six players on both sides already know what they will have to do next. It is the only situation a coach can prepare step by step at home, before the match begins. It is also the only situation where the quality of preparation is exposed without mercy.

A hard serve to position 1 forces the libero out of his comfortable zone. A short spinning serve to position 4 drags the outside hitter tight to the net and collapses the whole wing attack plan. A serve dropped into the gap between two positions forces the setter to run outside the three-metre line. None of those serves is recorded as a direct ace. Yet all of them produce points, just two or three beats later.

I have tried counting this kind of indirect scoring in a number of Vietnamese women's matches I re-watched. The rate varies by match, and my sample is small enough that I only write it in my notebook rather than publishing it as a measurement. But the trend is clear: teams with a varied serve repertoire always keep the rhythm of the match, even when the scoreboard shows they are losing the direct-ace battle. Conversely, teams that serve safely and evenly tend to win the pretty rallies but lose the long sets.

This is where I feel the greatest loss when I look at how Vietnamese volleyball is discussed. After every match the familiar question is who scored the most. The question that matters is where the third serve of the fourth set went, and which attacking plan it collapsed.

4. First pass: the most important number nobody publishes

Every rally is a full stop in a long sentence. But in volleyball, the first full stop is always the first pass.

Perfect-pass rate — the share of first contacts delivered to the right zone so the setter can run the full attacking menu — is the input metric for everything that happens afterwards. When it is high, a team can run the quick middle at position 3, pull the block at position 4 and then release the ball to the opposite wing. When it is low, the setter is forced to push the ball to the antenna, and the wing hitter is forced to attack into a block that has already read the play.

I have tried to imagine writing about Vietnamese women's volleyball without this number. It is like commentating a football match without knowing possession share. You can say Team A is stronger than Team B, but you cannot explain why Team A won the third set and lost the fourth.

There is a physical reason this metric matters even more in Vietnamese volleyball. The average height of Vietnamese women's teams is lower than opponents at continental level. When the net is higher and the opposing block is deeper, the only advantage a shorter team can create is speed and surprise. Both are born from the first pass. Without a good first pass, a shorter team must hit high balls, and a high ball in front of a tall block is a dead ball.

So when I hear a team described as weak in attack, I often wonder whether the problem lies in the legs of the hitter or the hands of the first receiver. In most cases I have logged myself, the answer is the second. People blame the attacker because the attacker is the one who gets seen.

5. Rotation and structural blind spots

I looked back at Hai Phong 2026 and realised the formation is only the shadow of victory.

That was the first data project of my life done seriously. In 2026, at 55, I built a spreadsheet tracking 108 of the 182 matches of the national league season, recording dead-ball positions, attack directions and the distance between lines. The headline finding that kept me awake was that 67 percent of chances — 128 of 191 situations — came from the two wings. I cross-checked against the previous five seasons and saw high pressing rise by 12 percent. True to my temperament, I checked every figure twice, discarded 14 matches as noisy, and only then published my first 2,500-word article. It drew 3,000 reads.

But what I learned was not the 67 percent. It was how that number changed when the rotation changed.

In volleyball, rotation is the structure that decides everything. Six positions, six configurations, and within each configuration a team may have two or three genuine front-row attackers. Rotations with only two attackers are structural weak points, and every opponent with video knows it. They will load the block onto those two, force serves into the position that keeps your blocker pinned, and wait for errors.

What is striking is how few spectators realise they are watching a weak rotation. The feeling will be that the team has lost its rhythm, that the setter is confused, that the main attacker is fading. All three remarks may be true on the surface, but they describe symptoms, not causes. The cause is how many real attackers are standing in the front row.

With rotation-level data, the story flips. You can see that Team A is efficient in rotations 1 and 4, weak in rotations 2 and 5, and therefore know where to improve: either change the serving plan to push opponents into unfavourable rotations, or coach the middle blocker to read situations better. Both can be trained at home. Neither requires a genius.

To do that, though, you need a rotation-level table. And that table, at least on Vietnamese courts, does not exist publicly.

6. Out-of-system attack and the superstar trap

The more I watch, the more I believe data is never in a hurry — only we are quick to conclude.

There is a category of point Vietnamese volleyball produces constantly and almost never names correctly: the out-of-system attack. These are rallies where the first pass is broken, the setter has no option but to push a high ball to one player, and that player must solve it alone against a block already set.

Players such as Tran Thi Thanh Thuy or Nguyen Thi Bich Tuyen do this at a high level, and that is why they have become irreplaceable pillars of Vietnam's women's team. But when a team depends too heavily on this kind of point, two consequences follow that the scoreboard never mentions.

First, the star's point total rises and teammates' totals fall, and nobody calls that a problem, because the star scores and the star gets praised. Second, and heavier: the team gradually loses the habit of building collective attacking plans, because collective plans require a good first pass, and a good first pass is far harder to drill than simply giving the ball to your best player.

I have re-watched matches where the underrated team beat the favoured team. In almost every case, the winner was not the team with the better star. The winner was the team that executed more attacks inside the system — rallies where all three attackers could receive the ball.

This is why I dislike reading results as Team A had better players and therefore won. It is true on the scoreboard, but it teaches viewers the wrong lesson: that volleyball is an individual sport. Volleyball is the sport where a great player can score 30 points in a defeat, and those two facts do not contradict each other at all.

7. Blocking, height and the forgotten touch

There is one volleyball metric I consider the worst-treated in every statistics table: the block touch.

Scoreboards record kill blocks — blocks that directly produce a point. But most good blocks do not score immediately. They slow the ball, deflect it, or force the opponent to attack again, and those rallies often end with a point for the defending side two or three beats later. The blocker who did the job right gets no credit anywhere.

In Vietnamese volleyball, where women's teams are often shorter than continental opponents, block touches matter even more. If you cannot stuff the ball, you must touch it to reduce speed so the libero can read the direction. A block that knows how to touch properly has higher tactical value than a tall block with slow feet.

The problem is that this metric never appears on the board. And when an effort is invisible, it will not be taught. I have sat with a few young coaches, and they all say the same thing: good blockers in Vietnam are discovered by the eye of a teacher, and if the teacher leaves, the skill leaves with him.

That is the cost of having no data. Knowledge is not archived; it is passed by word of mouth, and word of mouth is fragile.

8. The transfer window: where emotion burns money

During a transfer cycle, noise always exceeds signal. That is as true in volleyball as in any other sport.

On Vietnamese courts, volleyball contracts are often short, sometimes running only for one phase of a season. That means a club can change half its roster within weeks, and deals are usually announced in vague language. Contract structure — duration, clauses, release rights — is almost never made clear. What is made clear is the headline total, which is the least important part of a club's financial story.

I hold a professional bias I do not hide: I believe the price of young players is being inflated much too fast, in every sport, and volleyball is not outside that trend. In the big leagues, clubs have paid enormous sums for players who have not completed 50 top-level matches. In Vietnam the same phenomenon appears in a different form: a player who shines in one youth tournament or one SEA Games can be rated equal to someone with three stable national-league seasons.

The worry is not the money. The worry is that decisions are made on a sample that is far too small. A short tournament, a few good matches, a few viral clips — that is too thin a dataset to price a career. And when a club misprices, it does not only lose money; it creates false expectations for a young player who will have to live under that pressure for years.

My filter is simple: reading a transfer story, I ignore the headline fee and look for three other things — contract length, release clauses, and which club is paying the wage. Those three decide a club's actual behaviour. The headline fee only decides the headline.

9. The counterintuitive angle: pretty numbers born of futility

This is the part I want to spend the most time on, because it is the biggest blind spot in the whole sports-analysis industry.

There is a family of metrics packaged as measures of effort: distance covered, sprint counts, touches. They are presented as proof of commitment. And they are almost always wrong in one specific direction: they reward movement, not correct movement.

In volleyball, the local variant of this problem is the touch count. A libero with many touches is not necessarily a good libero. If teammates keep delivering the first pass into the wrong zone, the libero will have to run a great deal, touch a great deal, and produce an impressive-looking stat line. But that number measures other people's mistakes, not his own ability.

The same happens with an attacker's attempt count. A player who attacks 60 times in a match may be carrying the team, or may be hitting into a three-man block because the team has no other plan. Looking at the number, the two cases are identical.

The pandemic taught me that the silence of the stands is also a tactic.

In 2026, at 58, when European stadiums played in silence, I analysed 81 Bundesliga matches after the restart and found pressing intensity down 14.7 percent after the 70th minute. By old habit, I cross-checked against 2026 data and built a concept I called atmosphere as a tactical parameter. Because the sample was small, I concluded cautiously, wrote a three-part series stating its limits, and two university studies later cited my warning as a reminder to read statistics carefully.

That lesson applies intact to Vietnamese volleyball. A match with spectators and a match without are two tactically different matches, even with identical scorelines. A player who performs in front of 500 people and one who performs in front of 5,000 are two different players, even with identical stat lines. If we do not record these variables, we are comparing things that cannot be compared.

10. Method and data limitations

I always put these two sections at the end of every article, even when they make the piece less engaging.

On method: the figures cited here come from three sources. First, my personal spreadsheet tracking the 2026 national league season, covering 108 of 182 matches, with 14 discarded as noisy. Second, the dataset I built during and after the summer of 2026, re-watching 64 World Cup finals matches and logging every dead-ball situation. Third, the 2026 Bundesliga log, covering 81 post-restart matches.

On limitations: the observations about Vietnamese volleyball in this article are largely qualitative rather than quantitative, because rally-level data is not publicly released. My sample of re-watched matches is small. I have no coordinate-level contact data. I have no data on training load, injury status or player recovery conditions. Every conclusion here should be read as a hypothesis to be tested, not as a verdict.

I say this not to protect myself. I say it because I believe a sports analysis without a data-limitations section is an unfinished analysis. Readers have the right to know what I know and what I do not.

11. What to verify in the next round

Age 64 gives me a perspective I did not have 30 years ago. Thirty years ago I wanted to be right. Now I want not to be confidently wrong.

When in doubt, I go back to the footage and the data; they are always honest.

So in the next round I will not ask which team is stronger. I will ask three questions that can be answered with the naked eye, and write the answers into that empty spreadsheet.

First, which team holds a higher perfect-pass rate in the fourth set, when the legs are gone. Second, which team scores more from indirect serve sequences — serves that do not win the point directly but force the opponent into out-of-system attack. Third, which team records more block touches in rotations with only two attackers.

Those three questions need no expensive software. They need one person to stay behind after the match, replay the footage, and count patiently. Do that across enough seasons and we will have a dataset the next generation can open and learn from.

I am 64. I may not have enough time to finish that spreadsheet. But I can leave the column headers behind, and one reminder: don't conclude yet.
