What Vietnamese Volleyball Never Writes Down

What Vietnamese Volleyball Never Writes Down There was a match in the national championship where I stayed until the organisers turned off the stands lights. The official stats sheet handed to the press that night had one column almost blank: the defence column. The match was hardly short of digs. The fourth set alone had at least four live rallies in which the liberos on both sides had to throw themselves across the wooden floor. The column was blank only because there was nobody sitting beside the scorer to count with her. The scorer was a volunteer student, borrowing the organisers' tablet, and by the middle of the third set the battery was flat. I remember the first time I read a player's name wrong three times in a single live broadcast. That night I stayed in the archive room until morning, writing down every pronunciation, every nickname, in a small notebook. That notebook has stayed with me for seventeen years. It taught me one simple thing: sports data does not begin with software, it begins with somebody willing to sit down. A name mispronounced three times is still a true story, if you are willing to listen carefully. Vietnamese volleyball is at a stage where its audience is larger than at any point before. The women's team has finished with silver behind Thailand at several consecutive SEA Games, and each time the arenas have been fuller than the last. Faces such as Tran Thi Thanh Thuy and Nguyen Thi Bich Tuyen have gone abroad to play, bringing home a different standard of fitness and speed. The VTV Cup draws crowds every year, youth tournaments are beginning to be streamed, and highlight clips can reach hundreds of thousands of views in a night. But one thing has not grown at that speed: the habit of writing things down. I once spent two weeks in a fan zone during a World Cup, filming supporters who sang for ninety minutes even as their team lost. What I brought home was not a conclusion about tactics but a belief: anything worth remembering can be recorded, if somebody is willing to record it. Vietnamese volleyball has a great deal worth recording right now, and it is letting it slip away. At the major volleyball competitions of the world, a single match is recorded as hundreds of data points. They measure the perfect-pass rate, the share of first contacts delivered to the right spot so the setter can open the full attack menu. They measure attacking efficiency, blocks per set, the ratio of service aces to service errors. Those figures are not there to make a report look pretty. They are the language a coach uses with a player, a scout with a club, and one generation with the next. In our national league, most of those boxes are still left empty. The first consequence lies in selection. When nobody measures perfect-pass rate, judging a libero or a defensive outside hitter falls back on the feeling of whoever is sitting in the stands. That feeling is not wrong, but it is swayed by things that are easy to remember: height, build, a few beautiful plays in a televised match. A player a few centimetres shorter but steady in first contact all season will be harder to recall than a tall, hard-hitting player who shines now and then. Data does not replace the eye. It only keeps the eye from forgetting. The second consequence lies on the bench, where I have always tended to sit. A young player who gets twenty scattered minutes across a whole season leaves no trace in any statistical sheet, because the sheet was never written for her. Nobody knows what percentage of her first passes were perfect, how many balls she blocked, or simply whether the team lost its rhythm or kept it when she came on. The following season, when the club discusses a renewal, the only thing left is somebody's faint memory. Many careers close with a blank notebook rather than a missed ball. The third consequence belongs to tactics, and it is subtler. Volleyball has six rotations, and not every rotation is equally strong. Some rotations leave only two genuine attacking options, forcing the setter to push the ball to the wing for the weakest hitter. Without data showing which rotation costs the team the most points, a coach will fix it by substituting on instinct, usually replacing the weaker hitter rather than the structure. The same applies to out-of-system balls: a poor first contact, the ball delivered beyond the setter's control, the attacker left to solve it alone. Those are the rallies that decide matches, and the ones least likely to be recorded. At a deeper level, missing data erases the ability to compare generations. Fans still argue whether today's players are better than those of a decade ago, but arguing from memory has no end, because memory always wins on the side of the storyteller. A fully recorded league would allow two eras to be placed side by side and the numbers to speak. Without it, every comparison ends in sentiment. The usual response is to propose buying software, hiring analysts, importing a modern data system from abroad. I believe that order is backwards. Software does not create a habit; it only amplifies a habit that already exists. Introducing a modern statistical system into a league where nobody is used to sitting down after a match will only produce files nobody opens. Before talking about machines, the cheapest and hardest task is to rebuild one small ritual: after each match, the recorder reads back what was written, the coach listens, and both confirm which boxes are still empty. That ritual takes about thirty minutes and costs nothing. The same holds for the audience. Empty stands during the pandemic were not silence; they were the echo of the people who used to be there. I once sat in such an arena in Chengdu in 2026, when the women's team I was filming fell apart within a month and a foreign player cried and went home. In the summer that team dissolved, I learned that a team does not die on the court; it dies when nobody is left to tell its story. Data is the slowest, least glamorous way of telling a story, and also the most durable. A rally is a heartbeat, and a highlight is the heart monitor; people attach it so they can remember they were alive. But a heartbeat only means something when somebody also records the steady beats, not only the spikes. Vietnamese volleyball has enough players, enough audience and enough stories to move to another level. What it lacks may be just a notebook, a person willing to sit down, and one evening after a match. If every empty column is filled next season, what will be the first question we can answer with data?
