Vietnamese Volleyball and the Silence That Goes Unmeasured

In the semifinal of a national volleyball championship at a provincial arena, with the score at 24-23 in favour of the visiting team, the stands fell silent. Not a single shout. Not a single wave of people rising to their feet. Only the sound of the head coach's shoes tapping the wooden floor and the breath of the setter after a broken first pass. I sat in the press row, my laptop screen glowing white, and realised something that made my hands go cold: I had not a single number to write with. Not because the match lacked emotion. But because that tournament produced no line of data solid enough for a writer to hold on to. No first-pass statistics table. No attack-efficiency rate by position. No count of successful blocks. Only the final score, a few throwaway remarks, and the memory of those present. Vietnamese volleyball has existed like that for years — a sport that is loved, watched, and yet almost invisible to any serious record-keeping system. A VOLLEYBALL CULTURE WITH NO MEMORY To understand why that silence matters, it has to be placed against a wider backdrop. The SEA Games, the AVC Cup, the VTV Cup — the stages where Vietnam's women's national team appears — have all entered an era in which world volleyball measures almost everything. In Japan or Thailand, every set is broken down into dozens of metrics: attack efficiency, blocks per set, perfect-pass rate, successful digs. In Vietnam, most of those numbers do not exist — or if they do, they are scattered in the notebooks of a few coaches and never made public. The consequence is not that fans lack figures to argue over. The consequence is that the people inside the profession cannot properly evaluate a player. When you have no perfect-pass rate, you cannot know which libero truly holds the team's rhythm. When you have no attack efficiency broken down by net zone, you easily mistake a good blocking middle blocker for an effective attacking one. Selection decisions become instinct, and instinct favours familiar names. I once counted by hand. In my twelve-square-metre room, between two seasons postponed by the pandemic, I rewatched hundreds of rallies from an old national tournament, noting every broken first pass, every block that grazed a hand. That work taught me one thing: many players are misjudged not because they play badly, but because nobody records what they do right. THE NUMBER IS NOT JUST ON THE SCOREBOARD Take the first-pass system — the foundation of every attack. In modern volleyball, the perfect-pass rate determines how many attacking options a team can run. A team with good first passes can open three attacking lanes at once, forcing the opposing block to guess. A team with poor first passes has only one option left, and the opposing block simply waits. In Vietnam, people talk endlessly about spirit and very little about this rate. A spectacular dig draws applause, but a first pass that delivers the ball to the setter's hands — something far less glamorous — is remembered by no one. That is the paradox: the thing that decides the match is the thing least acknowledged. Poor data leaves a larger gap still: the ability to assess opponents. When Vietnam faces Thailand or the Philippines, the coaching staff must rely on video and memory, with no statistical file showing that the opponent's main hitter prefers a cross-court attack from position four or position two. Teams with complete data systems walk onto the court with a quiet but decisive advantage. TRAN THI THANH THUY GOING ABROAD IS NOT JUST A CONTRACT Within that picture, the fact that a few pillars such as Tran Thi Thanh Thuy or Nguyen Thi Bich Tuyen find their way to foreign leagues means more than a contract. Every transfer is a farewell named hope. In leagues such as Japan's or Thailand's, Vietnamese players are placed for the first time in an environment where every rally they touch is measured. They learn that a bad pass carries negative value, that a block which grazes a hand and flies out still counts as a success. When they return, they bring a new standard. But that standard collides with a domestic system still running on memory. The gap is not in fitness or technique. It is in the way people look at a match. THE CONTRARIAN VIEW: WHEN DATA BECOMES A TRAP But one thing must be said plainly, something Western analytics circles often avoid: data does not automatically make volleyball better. I have seen reports thick with metrics about a team — effective touches, block rate, attack efficiency — with not a single line about the fact that the setter had been exhausted since the third set, that she kept setting because there was no one to replace her. Data analysts are moving into the locker room, but their conclusions are often detached from the actual rhythm of the match. In Vietnam, we stand at an ironic crossroads. We are desperately short of data, but if we import data without importing the thinking behind it, we will build a system that counts a great many meaningless things. The silence of Vietnamese volleyball cannot be filled with numbers alone. It must be filled with numbers that someone understands how to read. That is the biggest blind spot. People assume the problem is a lack of machines, software, money. But the root problem is a lack of people able to watch a broken first pass and know it stemmed from the opposing block having read the setter's signal three rallies earlier. No software teaches that. SILENCE IS ALSO A FORM OF DATA At SEA Games 29, the silence of the stands was a lesson about the weight of belief. I remember a moment in Kuala Lumpur when a track athlete clipped a hurdle and sat down flat on the track. The whole stadium did not cheer, did not clap, did not react. That silence said more than any results table. Vietnamese volleyball has silences like that too — and we are wasting them. A volleyball team that does not celebrate after winning a set is a signal. A coach who does not stand up for the entire fourth set is a signal. A crowd that does not cheer when the home team equalises is a signal. Those negative signals carry information the scoreboard never touches. With a serious record-keeping system, we would know that team X wins through attack but loses at first pass, that player Y has the tournament's best defensive index yet is never called up, that player Z — who never appears in the papers — touches the ball more than anyone in every decisive rally. VOLLEYBALL AS AN UNTRANSLATED LANGUAGE In a twelve-square-metre room, 120 races taught me to listen to my own breathing. But volleyball taught me something else: to listen to the breathing of a collective. A volleyball rally lasting ten seconds contains more decisions than a half of football. Every person, every second, must choose the right position, the right timing, the right hand direction. A system that cannot measure those choices cannot claim to truly understand the match. Croatia did not run faster; they forgot they were allowed to stop. I wrote that about football, but it holds for volleyball too. Some Vietnamese teams win by knowing when to slow down — a slow but sure first pass, a slow but effective attack. But because nobody records how they slowed down, when that generation retires, the lesson disappears with them. Vietnam's women's national team is not short of good players. Doan Thi Lam Oanh, Le Thanh Thuy, Nguyen Thi Ngoc Hoa or Dang Thi Kim Thanh all left marks on the memory of viewers. But collective memory is short, and there is no data to hold it longer. When a generation passes, we are left with stories retold, not evidence. A THOUGHT TO OPEN, NOT TO CLOSE What troubles me is not the absence of statistics software. It is the absence of a habit of record-keeping. We have grown used to trusting our eyes, to the feeling of the moment, and forgotten that feeling needs to be anchored to something more durable. If tomorrow Vietnamese volleyball had a complete data system, perhaps the first thing we would realise is not who is best. It is how many players played well in silence, in rallies nobody counted, and retired without anyone knowing their names. That silence is the thing most worth measuring — and the thing we have missed the longest.
