That day I sat in the seventh row of an arena, holding the statistics sheet the organizers handed out after a semifinal of the national volleyball championship. On the paper were the two team names, the set-by-set score, a few lines of notes about sanctions, and a final column — the one that should have held each athlete's attack efficiency — left blank. It was not a printing error. It was simply that nobody had recorded it.

I stayed with that sheet for a long while. The stands had emptied, the arena lights had dimmed by half. A visiting-team coach bent down to pick up a water bottle and walked straight out the door without looking back at the scoreboard. That moment reminded me of a line I wrote years ago: “At SEA Games 29, the silence of the stands was a lesson in the weight of belief.” Today the silence sat somewhere else — on the very sheet my profession was supposed to fill.

My trade lives on numbers. But seventeen years in it have taught me that the most frightening thing is not a wrong number; it is a number that does not exist. A blank cell on a stats sheet does not say the match had nothing to tell. It says we chose not to tell it.

Context: a volleyball culture without a spreadsheet

Volleyball is among the most data-rich team sports. At a Volleyball Nations League or Japanese V.League match, organizers publish every touch: who received the serve, where they received it, where the ball went, at what efficiency, who blocked successfully, who scored an ace, who committed an error. A match lasting more than two hours generates a dataset thicker than a notebook.

In Vietnam, we know who scored the most points. We know which team won. But we rarely know why. A hitter scores twenty points in a match — it sounds impressive, but out of how many attempts? If it took fifty swings, that was a disaster disguised as a brilliant night. If it took thirty-five, that was a hitter carrying an entire system. Without a denominator, every compliment is a guess.

The Vietnam Volleyball Federation stages the national championship every year, gathering the strongest teams from the provinces and cities. The tournament has sponsors, television, an audience. Yet the public statistics stop almost entirely at points and set scores. The most basic metrics of modern volleyball — reception efficiency, perfect-set rate, blocks per set, ace-to-error ratio — barely exist in public space.

In Japan, where women's volleyball is one of the most followed sports, every round of the V.League publishes detailed statistics for each athlete, along with efficiency rankings by position. A Vietnamese hitter playing there would see her name appear in a ranking she does not have at home. What does that mean? It means an athlete can be fully measured abroad, yet become invisible upon returning home. That break does not lie in her ability. It lies in our information infrastructure.

The causes are easy to guess. Tight budgets. No dedicated statistics staff. Our sports culture still places results above process, and once the result exists, the rest is treated as surplus. But I want to say something harder to hear: we lack tools, and we also lack the habit of sitting down and counting.

In the professional volleyball world, a Vietnamese athlete going abroad is immediately placed inside a measurement system. She is tracked weekly, every metric is published, and she is compared with other hitters at her position. Hitters like Trần Thị Thanh Thúy or opposites like Nguyễn Thị Bích Tuyền, when they step onto the international stage, suddenly become more fully visible than they ever are at home. The movement itself is a lesson. “Every transfer is a farewell named hope.” For a writer of data, each transfer is also a chance to be seen — for the first time, one of our athletes is counted properly.

Core analysis: a number without a denominator

Let us start from the smallest unit. In volleyball, an attack can end in five ways: a direct point, a block, a shot out of bounds, a shot into the net, or a successful defensive save that turns into a counterattack. If we record only “point,” we throw away four of the five possible outcomes. And those four discarded outcomes are exactly where the coach needs the most.

I did by hand something nobody should have needed to do for me. In a recent season, I sat down with dozens of recordings of domestic matches and counted myself. I wrote down every attack by a few hitters I cared about, marked the outcome, and divided by the total. The result made me pause for a few seconds before writing on.

A player the press praised as her team's “main cannon” actually had an attack efficiency only slightly above average, because her errors and blocked attempts were too many. Another player rarely named had an astonishingly stable efficiency, simply because she knew how to refuse balls she should not hit. Without data, both were treated the same way in print: one celebrated for dazzling points, the other forgotten for modest but precious ones.

This is what I learned, and I will say it plainly: in volleyball, points are a number without a denominator, and a number without a denominator cannot be used to judge anything. A middle blocker who records four blocks in a set goes uncredited, while a hitter who scores fifteen points but concedes twelve still makes the front page. That injustice does not sit with the writer. It sits in the fact that we have no tool to write any other way.

Let us reconstruct the three minimum metrics any serious volleyball culture possesses. The first is attack efficiency: points from attacks minus errors and blocked attempts, divided by total attempts. The second is perfect-reception rate: what percentage of passes arrive in the right spot for the setter to organize a three-option attack. The third is blocks per set — a metric many international leagues treat as a direct gauge of reading the game. Those three numbers, added together, tell a story the scoreboard can never tell.

Sports writers fall into this trap too. When there is no data, the writer must lean on impression — and impression always tilts toward the loudest plays. A spike through the block draws louder applause than an accurate serve reception, even though that reception is what keeps the whole system standing. Journalism reflects that distortion, fans absorb it, and young athletes themselves learn to train for the moments that get remembered rather than the moments that get counted.

Vietnamese volleyball fans are not lacking in understanding. They recognize a good libero, they feel a middle blocker timing her block right. But that perception is locked inside the stands, with no path out into a shared language. A spectator can say “she played well” but has no way to prove it with a number. And when belief is not propped up by evidence, it becomes fragile — exactly the way a home crowd falls silent when its team loses a point in a deciding set.

I remember a lesson from a World Cup I once covered. While the whole newsroom chased the attacking stars, I was drawn to a team that did not run fastest but went furthest — the team that made me write: “Croatia did not run faster; they forgot they were allowed to stop.” Volleyball is the same. The winning team is not the one that spikes hardest. It is the one that controls tempo, that knows when to attack and when to yield. That tempo only appears through data — through efficiency, through error rate, through perfect receptions. Without data, tempo is invisible.

There was a period in my life when counting became a way to survive. In 2026, stadiums closed, the national athletics championship was cancelled, and the newsroom cut most of its sports output. Alone in a small room, I rewatched hundreds of old races and built my own tables of reaction time, flight time, and stride rhythm after thirty meters. “In a twelve-square-meter room, 120 races taught me to listen to my own breathing.” I learned that when the outside world goes quiet, counting is a way not to fall silent with it. Vietnamese volleyball is in such a room — not because of a pandemic, but because of a longer silence, a silence of habit.

The data void reaches even the transfer market. When a young athlete is courted by clubs, what determines her value is often a few moments replayed on television, not a season that can be measured. I have said that the bubble in young players' prices is slowly bursting — that paying a large sum for someone who has not played enough elite matches is a naked gamble. But in Vietnamese volleyball, that bubble does not even have data with which to burst. People do not pay high prices because of data; they pay high prices because there is no data to refute them. The absence of information, in the end, is exactly what drives the price up.

If I may propose one small thing, I would propose this: start with attack efficiency. Just one metric. In every match of the national championship, record each athlete's number of attempts and points from attacks, then publish it. With one added column, we have changed how an entire volleyball culture sees itself. From that column, people will start asking about reception, about blocking, about serving. Data does not spring from nothing; it springs from a person willing to sit down and count.

Contrarian angle: the void is not a failure

Here I want to go against myself a little.

The first reaction many have upon seeing a data void is to demand instant import: hire analysts, buy software, build a data center. I do not believe that is the right path. I have witnessed too many cases where data analysts walked into the locker room with beautiful charts disconnected from the real rhythm of the match. They drew conclusions from numbers they had never seen unfold before their eyes: a ball touching the block and changing direction, a libero lunging in an instant, a setter deciding in half a second. Data cannot replace presence. It has value only when anchored to someone who has stood there, who has heard the ball bounce on the floor and felt the tension of a set stretching to twenty-five twenty-three.

The paradox is this: Vietnamese volleyball lacks data not so much for want of tools, but for want of people willing to stay after the match. And precisely for that reason, the present void is an opportunity. A volleyball culture starting from zero has an advantage that data-saturated ones no longer possess: it can choose to count what truly matters, rather than inherit a pile of metrics nobody understands. The blank cells on my sheet that day were not a sign of failure. They were a blank page — and a blank page, to a writer, is always a beginning.

I do not want to turn the void into a tragedy, nor into a source of pride. It is simply something that needs to be named correctly. The real danger does not lie in lacking data. The real danger lies in pretending we already have enough.

Takeaway: when people learn to count what does not show up

That night, after leaving the arena, I folded the stats sheet and tucked it into my notebook. I did not write the article right away. I let it sit for a few days, as I do with things that need time.

Vietnamese volleyball will not change merely because one column of data is added. But a sports culture can only learn to speak about itself when it learns to count what has never been counted — the serve receptions that did not become points, the blocks that earned no credit, the balls refused at the right moment. Those are the things that do not show up on the scoreboard. And sometimes, the things that do not show up are the entire story.

I still keep that sheet with its blank cell. Not because I like emptiness. But because I believe that one day, someone will sit down and fill it with a number — and from that number, an entire volleyball culture will begin to know who it is.
