In the semifinal of the national women's volleyball championship, I sat in the seventh row, notebook open, counting. I was not counting points. I was counting the rallies that ended in silence — no cheer, no one standing, only the whistle and a referee's arm pointing to one side. There were eleven of them across four sets. Each time, a point was awarded. A point for a mistake.
That is the whole story of modern volleyball, folded into a hand gesture most of the spectators beside me never noticed. They came to watch spikes, blocks, and digs. They did not come to watch the rules. But the rules were writing the match in front of them, one point at a time.

When every microphone points one way, I choose to stand in the gap. And the gap this time sits inside the very rulebook everyone assumes they already understand.
Before 2026, volleyball was played under side-out scoring: only the serving team could score. A brilliant rally won by the receiving team earned only the right to serve, not a point. The result was marathon matches — some lasting three or four hours, with sets stretching far past 25 points with no ceiling at all. Television viewers walked away. Sponsors turned their backs. Volleyball, a beautiful sport, was strangling itself with its own patience.
The Sydney 2026 Olympics was the turning point. The International Volleyball Federation (FIVB) moved to rally scoring and has kept it ever since. Every rally, whoever serves, ends with a point. A set ends at 25 points, provided a team leads by at least two, with no upper limit. A match is best-of-five, first to three sets. And the fifth set — the decider — is played to just 15 points.
This rulebook governs every competition, from the Olympics to Vietnam's national championship, from the senior women's team to the youth squads. Understanding it is not about memorising. It is about understanding why a coach substitutes in the third minute of a set, why a libero matters so much, and why one small error at the three-metre line can swing an entire match.
Here is what I consider the core point, and it is usually skipped in commentary booths: rally scoring turns every mistake into a debt paid immediately. Under the old rules, a missed serve merely cost your team the serve. Under the new rules, it is a point for the opponent, instantly, with no negotiation. This pushes tactical priorities toward stability: reliable serving, tight blocking, error-free defence.
According to data from the scoring-tracking platform KeepTheScore, compiled across roughly 700 matches, sets that stretch to 24-24 or beyond — deuce — account for only 8 to 9 percent. The average set score sits around 25-17. Most sets are not dramatic at all. They end with an eight-point margin, and they end on mistakes punished at the right moment.
That is why I keep telling young players: in modern volleyball, you win by not losing. It sounds paradoxical, but the data backs it up. Based on my experience watching matches, a team with strong ball control but no outstanding attacker often troubles opponents more than a team with an attacking star and a loose back row. The new rules made that a systemic fact rather than a subjective opinion.
The best-of-five format tells its own story. The data shows the average number of sets in a best-of-five match is four. The most common result is 3-1, not 3-0 and not 3-2. That means a team entering a tournament expecting a quick win, or expecting a thriller that runs to a fifth set, is preparing for a less likely scenario than reality. What they need to prepare for is four tight sets, evenly distributed fitness, and a lost set swallowed without psychological collapse. Under best-of-three, the average is only two sets, and 2-0 sweeps clearly dominate.
Rotation is the most underrated element. The rules require six players to stand in the correct rotational order at the moment of serve. A positional fault is not a minor slip: the team loses the point and the serve. For women's teams in the national league, where players often train less and have less access to analysts, rotation faults are among the quietest ways to bleed points. I once counted three such faults in a single set of a quarterfinal, and all three came at moments when they should never have happened.
The libero is the tool for managing that rotation pressure. This differently coloured player can be substituted freely for back-row teammates without counting as a formal substitution. But the libero is barred from serving, from blocking, and from attacking a ball entirely above the net. In other words, the libero is a pure defensive specialist — and the existence of the position says something about the sport's philosophy: good defence needs to be protected by the rules, not merely praised.
The other positions follow a clear template too: setter in 2 and 1, outside hitters in 4 and 2, middles in 3 and 6, opposite in 2 and 1. This is the foundation of the 5-1 and 6-2 systems every team runs. Each position carries its own skill set, and a team that builds a roster without accounting for that pays in concrete points.
The basic faults deserve a mention too, because they generate most of the points in a match: the three-hit limit, net contact, a back-row attack from inside the three-metre line, and crossing the centre line. Each is punished with an immediate point. A weak server is no longer just a tactical weakness; she is a scoring channel for the opponent.
One subtle detail the new rules inadvertently created: teams can deliberately target the rotation of a weak server, forcing errors or unfavourable net matchups. It is a tactic written in no rulebook, yet present in every elite match. The two-point margin requirement, with no ceiling, guarantees that no set ends in a tie. Every set must produce a winner. That is a fairness mechanism, but it is also a mechanism of extension.
Meanwhile, beach volleyball — the other branch of the same sport — uses a similar but shortened structure: sets to 21, a deciding set to 15. The similarity is no accident. It is a deliberate effort to let fans move between the two branches without relearning the game.
One notable thing is that the rulebook itself still has gaps in mainstream coverage. The Video Challenge system is now standard at FIVB events, yet very few rules explainers for new fans mention it. Spectators are taught how points are scored but not how a point can be overturned.
And here is where I want to say something that may displease a few colleagues in the commentary booth.
The fifth set to 15 is marketed as a way to create a sharper finish. That is true in terms of duration. But in essence, a 15-point set does not make the decider fairer — it makes it more random. Fewer points mean fewer chances for errors to be corrected. A team that plays better for two hours can lose everything because of seven shaky opening minutes. The format is designed to increase drama, and drama, in the end, is a trade against certainty.
I also wonder what that 8-9 percent deuce rate tells us. Television sells us the image of breathless 24-24 sets, rallies where the whole arena holds its breath. In reality, more than ninety percent of sets never get there. Most sets are decided before anyone stands up. This does not make volleyball less compelling. It simply means we are being shown an edited product, not a raw one. And when new fans arrive at the arena with the wrong expectation, they are disappointed — not because the match is bad, but because it is different from the advertisement.

There is one more thing. I have followed Vietnamese women's volleyball for years, and I have noticed that women's teams are often underestimated in precisely the dimension the new rules elevate most: discipline and ball control. When a match is decided by who makes fewer errors, rather than who hits harder, that is a stage where fundamental technique rules. Yet we rarely hear that said in the news. Instead, people prefer stories about the spike, the star, the moment of brilliance — the flashy things that do not decide most results.
No one gave me airtime, so I went looking for ears that had never been served. Volleyball's rules changed so the sport could survive on television. But is a sport optimised for television still the sport we love? And I do not only tell the match; I tell about the people ranked below the scoreboard — people for whom a net touch, a foot across the line, can be the entire difference between a season and a career.
