On August 12, 2026, at Earls Court in London, Russia's men's volleyball team walked into the fifth set against Brazil trailing 0-2. They had already stared down two match points in the third set, at 22-24, and survived. The third set stretched to 29-27. In the deciding set, Russia won 15-9 and took Olympic gold. The match ran nearly two and a half hours, yet the fate of a gold medal was compressed into its final fifteen points.
One night earlier, Brazil's women beat the United States 3-1 to claim the title. Two finals, two different scripts, one shared rulebook. That rulebook is twelve years old, and it is the product of a decision many Vietnamese fans have grown so used to that they no longer notice it.

Before 2026, only the serving team could score. To win a point, you first had to win back the serve. The consequence was sets that could run endlessly; one match at the 2026 Olympics consumed nearly three hours. Broadcasters began to turn away, and FIVB was forced to choose the simplest fix: award a point after every rally, no matter who served.
From Sydney 2026, the new rule took hold. A set is won at 25 points, with a minimum two-point margin and no ceiling. The fifth set, the decider, is played to 15. Beach volleyball follows a parallel structure with 21-point sets and a 15-point decider, so viewers can move between the two courts without relearning the game.

For Vietnamese fans, this system is second nature. The national championship, the VTV Cup, and the women's national team's matches on the Asian stage all run on rally scoring. But familiarity hides the most important part: rally scoring turns every mistake into a point lost immediately, rather than merely surrendering the serve as under the old side-out rule. A faulty serve, a mistimed block, a rotation error — each is now paid for in points on the spot.
That is the single largest tactical change in the sport's history, and it explains why modern volleyball prizes stability over bursts of brilliance. When every rally has a price, the team that errs less wins, rather than the team that owns a few flashes of genius.
Accumulated data from hundreds of international matches offers a few figures worth pondering. The share of sets that reach deuce — 24-24 or beyond — is only about 8 to 9 percent. The average set score lands near 25-17, an average margin of eight points. In best-of-five play, the median number of sets played is four, meaning a 3-1 result is the most common outcome and a fifth set is the rarest scenario.
In other words, most sets are not close at all. They are decided by the team that controls the ball better and errs less, not by miracle plays in the final minutes.
The London 2026 final illustrates both faces of this. In the third set, Russia survived two match points — a moment dramatic enough for the press to call it a miracle. Look closer, though, and it was the product of a specific tactical decision: coach Vladimir Alekno moved Dmitriy Muserskiy from middle blocker to opposite, and Muserskiy finished the match with 31 points — the fruit of a personnel call calculated while his team was backed against the wall.

Behind the baseline, the libero role says just as much. A libero may be freely substituted in and out for back-row players, yet is barred from serving, blocking, and attacking balls fully above the net. Brazil's Sérgio Santos was the archetypal libero: he scored not with spikes but by keeping his team from losing points. Under rally scoring, that is a form of value no one can replace.
So why does the press still love to sell a 24-24 scene? Because it is a professional instinct — to sell the tense moment. But if only 8 to 9 percent of sets reach deuce, then treating 24-24 as the standard for a volleyball match misleads viewers about the nature of the sport. Prejudice is a track with hurdles, and the record-breaker is the one who runs through them — even when the record is simply understanding a rulebook correctly. People call it a miracle; I call it fifteen points a team chose not to let go.
The 15-point fifth set is a deliberate design: it compresses variance. The shorter the set, the heavier a good serving run or two straight errors become. The stronger team gets no insurance from time, which is why fifth-set comebacks are so memorable — and why they so rarely happen.
For Vietnamese volleyball, the lesson lies elsewhere. We are not short on good players or dramatic matches. What is missing is the patience to read a match through the indicators rarely mentioned: safe-serve rate, rotation-error count, sets won by five points or more. To go further on the Asian stage, we may need to start by teaching viewers again that a good volleyball match is not found in a 24-24 scene, but in how a team chooses not to err across twenty-five points.
We do not watch a volleyball match; we watch a life told in five sets. And most of those lives are written in the quiet of mistakes avoided.
