Twenty-three times. That is how many times I counted the marker N/A in an analysis file that landed in my inbox at one in the morning in Milan. No source headline. No information points. No team names, no athlete names, not a single rally recorded. Nine analytical dimensions — tactical and technical, data, competition system and schedule, landscape and positioning, governance and compliance, team building, risk surface, public narrative, industry transmission — all returned the same sentence: insufficient information to conclude. The four-criterion information-value table earned one empty star out of five across the board. The risk matrix sat empty across six rows. The industry value-chain diagram held three curly-bracketed boxes with N/A repeating inside them.

I sat with it for a long while. Outside the window, the last tram of the day turned the corner, its steel wheels grinding the rail loud enough to sound like they were in the room. And I realised I was holding the most honest document I had read in months.
The final stride always begins at the starting line of an afternoon nobody remembers. There is no stride in this file. Only the starting line, and a long emptiness behind it.
When the sports industry learned to package data
In ten years of watching this industry, I have seen the analytical machinery change faster than the rulebook. A single men's volleyball match in Italy's SuperLega now generates thousands of data points: spike success rate, blocks per set, the ratio of service winners to service errors, perfect-pass rate, dig rate. Federations and competition organisers build two-stage pipelines: stage one breaks a source text into discrete information points, stage two reassembles them into nine deep-analysis dimensions. It sounds reasonable. Until stage one returns an empty box.
When I began writing about volleyball for the Italian market, each match gave me two sources: the referees' scoresheet and the organiser's scoreboard. Today I also have motion-tracking data, heat maps of blocking positions, and training diaries that some clubs publish selectively. The volume of information has grown. The share of it that is actually usable has not grown with it.
That pipeline does not invent errors. It only amplifies whatever is fed in. When the input is an article with no headline, no source and no data, the only correct output is a report saying it knows nothing. The problem lies elsewhere: very few newsrooms accept that answer.
A structured void
At stage two, this report does one thing I wish I saw more often. It tags every line of inference with a confidence level, and here that level is N/A across all nine dimensions. It refuses to build a fake comparison table, refuses to fill blanks with numbers, refuses to write "estimated at around" in order to plug a gap with a belief.
My trade usually does the opposite. I have read hundreds of volleyball analyses in which the author had no blocks-per-set figure, so they wrote about "spirit". No perfect-pass rate, so they wrote about "character". No head-to-head data, so they wrote about "tradition". Every time, a data gap gets sealed with an adjective.
Based on my experience following matches, the markers of that kind of piece are obvious. The data section runs two lines. The emotional commentary runs two pages. The stats table holds exactly three metrics, all of which can be found on the league homepage in thirty seconds. The "unknowns" section opens with a rhetorical question and closes with the same question.

Volleyball metrics have a feature few notice: they measure outcomes, not decisions. Spike success rate tells you how an attack ended, but not whom the setter chose and why. Blocks per set tells you how the front line held, but not who read the set direction before the ball left the opponent's hand. Perfect-pass rate measures the whole system, yet two passes off by half a knuckle change the meaning of the entire table. Real analysis begins exactly where the metric stops — at the decision, not the outcome.
On 7 July 2026, in Manila, Vietnam's women's national volleyball team beat Belgium 3-0 in the FIVB Challenger Cup final, earning a first-ever berth in the 2026 Nations League. I remember reading at least four analyses of that match within twenty-four hours of the final whistle. Three of them contained no metric beyond the three-set score. One had numbers — Tran Thi Thanh Thuy's spike success rate, the middle blockers' count in the last two sets — and that was the only piece that explained why Vietnam pulled away in the third set rather than the first.
Data does not make a piece better written. Data makes a piece more accurate, because it exposes the mechanism.
On 10 August 2026, in Paris, France's men's national volleyball team beat Poland 3-0 to keep the Olympic gold, a second consecutive title after Tokyo 2026, where they beat ROC 3-2 in a five-set final. Two finals, two entirely different scripts, one team. Read only the scores and you conclude France were far stronger in Paris. But look at the point structure in Tokyo and most of the fifth-set margin came from a run of pressure serving and blocks forced out of bounds by the opponent — things that appear in no scoreboard anywhere. People remember the score. I remember how he tied his shoelaces before the starting line.
At European youth events, I once watched a seventeen-year-old attacker carry more than forty attack attempts in a quarter-final. Nobody recorded that figure, because the event publishes no detailed statistics. Youth competition is where greatness begins from tumbles that never make the minutes — and also where bodies that are not yet grown get pushed into adult match rhythm, then pay for it with a knee at twenty-two. When there is no data, nobody sees that price. When there is data but nobody reads it, the price remains, only now nobody is accountable for counting it.
The regular season teaches me the same lesson on another floor. The pressure of continental qualification and the fear of relegation produce matches where pretty metrics save no one. Every time the referee team leaves the court to review a hand-contact touch on a monitor, the rhythm cools for a few minutes, and that cooling appears in no statistical column. Longer review times do not make a match fairer. They only make it slower.
The report also left behind a table of signals to track, and that is the part I found most interesting. Signal one: stage one is resubmitted. Trigger condition: a headline, a source, and at least three information points. With nothing within forty-eight hours, the file closes by protocol. A system that dares to define in advance what would change its mind, and defines as well how it gives up.
The blank report is more honest than the full one
There is an implicit assumption in the analytics trade: a long report with many tables and many arrows beats a short one. That N/A file contradicts the assumption, and that is exactly why it deserves keeping.
It does not invent a subject of analysis. It does not graft a team onto data that does not exist. It does not build a six-row risk matrix with N/A in every cell and call that a "comprehensive assessment". In the first-level risk warning, instead of describing a hazard that does not exist, it states plainly: no information to assess risk, please resubmit complete input. That is the behaviour of a disciplined system.
What worries me more is the default human response to a void. When the table is empty, the writer's hand reaches for the pen. Production pressure does not permit filing a document containing only the letters N/A. So the void gets filled — with guesswork, with blurred memory, with a story overheard in a stadium corridor. Breaking news will cool. But a hastily written story can become a distorted inheritance.
In 2026, I followed the World Cup from Milan on a screen and wrote a series on Croatia's tactics. I drew diagrams, counted passes, compared midfield pairings. Only when Croatia reached the final did I realise I had missed an entire layer beneath the diagram: how a group of players under Luka Modric rebuilt internal trust after years of division. I had to rewatch all seven matches, noting every moment of on-pitch interaction, before I understood why that team went so far. Since then, every analysis of mine must carry two layers: the tactical surface and the psychological layer beneath.
I have been on the other side of that mirror. At seventeen, in my first interview with Italian 400m hurdler Alessandro Sibilio at the European youth athletics championships in Grosseto, I asked the wrong question about his personal best, misspelled his coach's name, and had to publish a correction. A misspelled name is easy to fix. A filled void is not — because the void once filled stays in the piece, looking exactly like a fact, and there is nothing left for anyone to check.
What remains
The regular season teaches me that most sports stories live in the data nobody has collected. The glance before a serve. The breathing of a setter in the fourth set. The stillness between two blocks. Those things sit outside the stats table, but they are not fiction either — they lie in the observation zone I have to go sniff out myself.
The match can end. The obsession with the story I missed runs a marathon without a finish line. That file with twenty-three instances of N/A still sits in a folder of its own. It says nothing about volleyball. It says a fair amount about how we handle silence.
