The Empty Column in Women's Volleyball Data

I once received a nine-part report. It had a title, tables, a tactical assessment section, a risk section, even a glossary of technical terms at the end. Every cell in every table was neatly ruled. And every cell was empty.

The person who sent it to me was not lazy. She followed the correct process: she checked the input, found the raw data to be empty, and marked "insufficient information" on every line instead of inventing conclusions. That was a correct professional decision, and a lonely one. In sports media, an empty report is always harder to sell than a full one — even when the full one is guesswork dressed in jargon.

I recognised it because I once wrote something similar. In 2026, at a women's semifinal in Osaka, I was the only reporter in the press area taking tactical notes. Someone had removed my chair. I stood in the corridor and watched the whole of extra time, then went home and wrote about the seating instead. Three weeks later I sat down with the tapes to understand how the teams had actually played. The hidden chair did not make me fall; it taught me how to stand firm inside a press tribune.

Women's volleyball is in the middle of a transfer window. This is when the noise is loudest and the signal weakest. Reports are full of unsourced figures: an outside hitter "operating at 48% efficiency", a libero "defensively stable", a squad "getting younger". Nobody asks which formula produced that 48%, across how many rallies, against which opponent, in which league.

What actually decides a deal sits in places few people read: release clauses, salary structure, the international transfer certificate, and an injury that has not healed. Every transfer contract is a story of leaving — I listen for the silent crying too.

In Japan the pressure also comes from the calendar. A player grinds for her club in the SV.League while serving national-team duty in the FIVB's Volleyball Nations League. The gap between the two is rarely long enough for the body to regenerate — only long enough for a newspaper to finish writing about a "lightning comeback". Return timelines are controlled by club communications staff, and "wait until the weekend" almost always means the injury has not healed.

Across eight years covering women's volleyball, I have learned that the most common failing in this trade lies in unlabelled data, not in missing data.

Take the clearest example: spike success rate and spike efficiency. Success rate divides spike points by total attempts. Efficiency subtracts spike errors and times blocked from the points before dividing by total attempts. An outside hitter with a 45% success rate but 18% unforced errors and 12% blocked will post a true efficiency of roughly 15%. Look at the first number and she is a star. Look at the second and she is burning her team's balls.

Media pick the first number because it looks better and is easier to obtain. People see the score; I see the balls lost before the point arrived. In Data Volley scouting sheets — the standard most professional leagues use — the two figures sit in two different columns. One writer who cannot tell them apart, and an entire analysis is wrong from the first line.

The second suspect figure is the perfect pass rate. Under FIVB definitions, a perfect first contact is a ball delivered to the right spot so the setter can run the entire attacking menu. At domestic league level, many outlets count only a "good pass" — the ball goes up, but the setter's options are restricted. Same name, two definitions, two different results. A report citing "62% perfect pass rate" without naming the convention cannot support any conclusion at all.

What matters more is that the reception system shapes a team's entire face. A first-contact structure of two or three passers plus the libero determines how much of the attack menu the setter still holds. A team with a weak reception system loses the middle attack and is forced to the wings — and once only the wings are available, the opposing block needs just two committed blockers. That is when a rotation gets stuck. The team bleeds points, and nobody looking at the stat sheet can see why, because the sheet only records who hit out.

In a transfer window, one more figure is routinely misused: blocks per set. Blocking is the most opponent-dependent statistic in volleyball. A middle blocker who stuffs a weak setting team will post beautiful block numbers, then carry that figure to a new club where it never replicates. Nobody adjusts for opponent quality, so the block rankings keep misplacing players.

In 2026, when leagues restarted after the shutdown, I sat in a near-empty arena in Osaka, roughly 150 people admitted under the rules. There I heard what a full stand never lets you hear: the captain shouting to correct the reception shape in the very first second, the libero calling out the blocker's name, the ball striking the floor. An entire system running on sound, and I realised that system had always been there, buried under noise. Moscow taught me that control is not for suppression, but for keeping the rhythm of hope. Those empty stands taught me the same lesson differently: with no crowd roaring, you hear the sound of the organisation itself.

The international transfer certificate is mandatory whenever a player changes federation, and it is often the link that keeps an announced deal from taking the court. Few reports track that link, even though it explains most delayed debuts.

The usual reaction to an empty analysis is to conclude the writer lacked data. I think the problem sits on the opposite side: this industry has a surplus of unlabelled data, and that surplus is more dangerous than any shortage.

A figure without a definition still carries the authority of a figure. It gets quoted, dropped into a slide deck, used to price a player. Nobody can trace it back to a source, and nobody wants to, because tracing it would cost a good story.

Another danger lies in the template itself. A document with headings, sections, tables and a risk page automatically feels professional, even when the content is hollow. Format is a credibility signal, and that signal operates independently of truth. The nine-part report I received is the perfect example: it was honest to the point of emptiness, and precisely for that reason it looked more trustworthy than many a data-stuffed piece I read that same week.

The next blind spot is timing. During a transfer window, injury information is almost always released by the club, and the club has an obvious interest in keeping return dates fuzzy. Reporters have no access to medical files, so the only way to verify is cross-referencing: is the player training with the squad, did she appear at the open media session, is she on the registration list for the most recent match. Those three data points say more than one press release.

Women's volleyball does not lack stories. It lacks a small discipline: every figure must come with definition, scope, source and date. I write from the corner of a forgotten room, so that the forgotten have somewhere to stand. When a twenty-year-old outside hitter is valued by an unlabelled figure, the person who loses is not the one who wrote the piece.
