Nine Analytical Dimensions, Not a Single Line of Data

Nine Analytical Dimensions, Not a Single Line of Data

Minute 52, Saint Petersburg, July 2026. I was in the operations room of a sports channel, a live data board in front of me. I pushed a line of data across to the commentary desk: Jan Vertonghen had covered 7.9 kilometres, his average speed down 23 per cent on the first half. Belgium were pushing forward, but their back line was breaking from the inside. The commentator waved the line away and carried on talking about fighting spirit. Minutes later, France scored, and the goal came through exactly the gap Vertonghen's legs could no longer close.

Three weeks later I sat through all 64 matches of that World Cup again, checking every metric against every passage of play, and wrote two hundred pages on forecasting through fatigue indicators. I thought it was the most important document of my life.

Then I received another document. It had nine chapters, complete with headings, tables, conclusion blocks and evidence sections. And not one line of football data. Every cell read "N/A". It taught me more than the two hundred pages did.

1. Anatomy of an empty report

That document was a second-tier analysis, designed to dissect a football article across nine dimensions: tactics and technique; club finance and the transfer market; the results and public-opinion cycle; league landscape and team positioning; rules and governance; management and the dressing room; risk profile; media narrative and expectation; and finally the transmission chain of the wider industry. Each dimension carried a table, a scoring scale, a conclusion block, an evidence block, and a hidden-information block.

The problem was upstream. The first-tier text extraction stage, where a source article is converted into a list of information points, returned an empty list. No title. No source. No author stance. No article purpose. Not a single entity identified, whether player, club or competition. The only surviving datum was a domain label: football.

Yet the output still had a full body. Nine dimensions. Nine tables. Every row filled with a blank placeholder, carefully framed. Skim it for thirty seconds and you would think it was a serious document. It had a table of contents, formatting, professional vocabulary, even a glossary at the end. It was missing exactly one thing: football.

What strikes me is that the report did not lie. It stated plainly what it lacked, dimension by dimension, in a dedicated section titled "required to activate this analytical dimension". The tactics dimension needed formation, playing-style label, expected goals, expected goals against, pressing intensity, pass completion, and named players with roles. The finance dimension needed broadcast revenue, commercial revenue, wage bill, net debt, transfer fees, contract length, sell-on clauses. The results dimension needed a competition, a table position, a recent sequence with scorelines and specific dates.

Add those nine lists together and you get something more useful than any conclusion the report was supposed to deliver: a minimum data checklist. Every number is a confession, if we are patient enough to listen. Here, silence was also a metric. It equalled zero.

At the end, the self-assessment of information value awarded one star out of five in all four categories: sporting value, industry value, timeliness value, reference value. I kept that self-assessment. A system willing to give itself one star is a system still capable of self-doubt.

2. The template and the trap of filling the gap

Every analytical system needs a template. A template stops the writer forgetting to check the finances, forgetting to ask about contracts, forgetting to raise the dressing room. But a template has a side effect: it creates pressure to fill. An empty cell in a spreadsheet refuses to sit still. It makes a noise.

In a system built on a language model, that pressure becomes a concrete behaviour: filling the gap with something that sounds plausible. That is the hallucination risk the report itself flagged as medium. I think that rating is too low. Fabrication in football does not have to be a big event. It can be an adjective. This midfielder is quick. This defence is loose. Every adjective is a blank cell filled with belief.

The image I use with young people in the industry: a dress uniform, pressed flat, medals pinned, sitting on a stand. Nobody is wearing it. On a football pitch the same thing happens every week. A team lines up in the right shape, with eleven correct positions, and not one idea. An empty report is the paper version of that match.

The annual season in Vietnam creates ideal conditions for this kind of error. Many matches, short gaps between them, daily content pressure. When three matches fall on a weekend but only one has thick data, the other two get written in descriptive language. Descriptive language is not wrong. It simply measures nothing.

3. V.League 2026: when the data exists and nobody listens

In 2026, aged 53, I took a role as data consultant for a club in Saigon. I built a system tracking twelve movement metrics per player: high-intensity distance, number of pressures applied within five seconds of losing the ball, share of passes into the final third, and nine others.

On matchday 18 the team faced a strong opponent from the capital. I saw young midfielder Nguyen Trong Huy cover 8.2 kilometres across 90 minutes, 15 per cent below the team average. He was not lazy. He was simply no longer in the right place at the right time, and that showed up in the data before it showed up in the eye. I recommended substituting him on 60 minutes. The coaching staff shook their heads. The team lost 1-3.

After the match I presented a fourteen-page analysis. From the following round, the coaching board began following my adjustments. The team finished the season fifth, four places above the pre-season forecast.

I tell this story for a different reason: a paradox. In 2026 the data was there, correct, and still waved away because it contradicted the feeling in the dressing room. The empty report is the reverse face of the same disease. One side has data nobody will read. The other has no data that everybody believes they have read.

4. World Cup 2026 and the emotion filter

Back to Saint Petersburg. The commentator that night was not wrong. Belgium's fighting spirit was real. It simply could not be measured in the moment, whereas Vertonghen's legs could be measured, and were measured six minutes before the goal arrived.

Data never lies, but the people reading it do. In that operations room, the data was right and the reader chose wrong. This is the point I want to press on anyone who believes that having enough numbers will make everything obvious. Having numbers is not enough. Someone has to be willing to read them before the event, not after it has become a headline.

Fatigue is a process. A goal is an event. People record events, so they always start the story at the goal and skip the slowing legs that preceded it. World Cup 2026 taught us that emotion is the hardest noise to filter out of data. Hard to filter does not mean impossible. It means the person doing the filtering has to work before the crowd gets excited.

Compare the two things I have described: a commentator discussing spirit without verification, and a report with nine dimensions and no data. Both speak without evidence. One has too much emotion, the other has none of the numbers. The result is identical: the reader receives nothing to check.

5. Euro 2026, Vietnamese players, and the delayed report

In 2026, aged 57, I studied the effect of Euro 2026, pushed back a year by the pandemic, on the physical condition of Southeast Asian players. I found a number that cost me sleep: six players in the Vietnam national squad had played more than 2,800 minutes in the domestic season before entering World Cup qualifying. I sent a recommendation to reduce the load on Nguyen Quang Hai for the match against the UAE. The recommendation was never answered.

Quang Hai suffered an ankle injury in the 23rd minute of that match. The team lost and surrendered its advantage in the race for a deeper run.

I then gathered data on 40 Southeast Asian players who featured at Euro and the Tokyo Olympics. 57.5 per cent of them declined by an average of 18 per cent in the two months after the tournament. A German researcher later used the report in an article on the post-tournament syndrome.

Euro 2026's injuries were not a curse, but a report filed late. This is where I want to pause, because it connects directly to the empty document. A recommendation nobody reads before the match becomes an obituary after it. An empty analysis nobody catches before publication becomes a citation for ten other articles. Both are reports that arrived late. The difference is that one hurts while the other spreads.

Since then I have changed how I write. Every recommendation I make is now conditional: if X happens, consequence Y arrives within Z rounds. I no longer speak with certainty. Not because I lack confidence, but because I am old enough to know that the only certainty in football is uncertainty, and the job of the data person is to describe it accurately, not to hide it.

6. Four risks the empty report admitted itself

The report listed four risks against itself, and all four apply to football content generally, in Vietnam as anywhere.

First is silent upstream data loss. The input stage fails but still emits a valid label. In a newsroom, its version is a broken source with the headline still published.

Another is untraceable sourcing. When the source field is blank, the analyst cannot separate verified reporting from rumour. In Vietnamese football, a transfer story on a fan page and one from a press-room briefing can look identical after an editor has handled them.

What worries me most is fabrication to fill the template. This risk is dangerous because it produces no obvious error. A wrong metric can be caught by cross-checking. A fluent invented paragraph cannot.

Last is the absence of an error log. The system stays silent when it fails. The operator does not know why the report was empty: blocked retrieval, paywall, empty document, or parse error. Nobody logged it, so nobody can fix it.

Those four risks collapse into one principle I would pin to the wall of any sports desk: if a preview has no metric, no source and no proper noun, it should not be published. Not because it is bad, but because it cannot be verified, and what cannot be verified cannot be corrected.

7. The minimum list for an analysis to count as real

From those nine dimensions I extract a minimum list. For each match: formation, playing style, expected goals and expected goals against, pressing intensity, pass completion, named players with roles, and opponent type. For each transfer story: fee, wage, contract length, clauses, player age, and the reporting source.

Miss any of those and the piece can still be written. It just stops being analysis. It becomes description.

One technical point deserves attention because it is so often misquoted. The lower the pressing metric, the more aggressively a team presses, because the metric counts the passes an opponent completes before you make a defensive action. It sounds counter-intuitive, which is why it gets used wrongly. I have seen previews describing a team as pressing high while their metric was rising. Rising means opponents were completing more passes before being stopped. That is the signature of a midfield out of fuel, not one bristling with intent.

8. The transfer market and the price of hope

The transfer market is the only place where people pay for hope rather than achievement. Nobody buys a player for what he has done. They buy him for what he might do over the next four years. That makes it the environment with the highest density of fake information in football, and the place where templates get filled most.

A few concepts are worth knowing for self-defence. Transfer fees are usually amortised evenly across the contract, so an expensive signing can look light in the first year's accounts. A sell-on clause means the selling club still takes a percentage of a future sale, so the headline figure is not the final figure. A panic premium is the amount paid above fair value under deadline pressure. And the contract-year effect changes a player's form according to the negotiation calendar rather than the fixture calendar.

None of that stops a bad story. But it helps you ask the right question: where does this number come from, and who benefits if I believe it?

There is a more delicate point. When a club suddenly succeeds, its key players are usually dismantled quickly by richer clubs. Success becomes the opening act of another talent raid. That is a market law, and it is measurable: average squad age, remaining contract years, and the wage-bill gap against the tier above. Those three metrics tell you in advance who is leaving next season.

9. Women's football and the polished label

I saved this section for near the end because it is the cleanest example of an empty report wearing a progressive face.

Much writing about women's football is done in the language of community development: empowerment, inspiration, widening opportunity. Those words are not wrong. But they often substitute for the metrics that should be there: broadcast minutes, share of rights revenue, wage-bill proportion, actual attendance round by round.

When a women's competition is sponsored as a corporate social responsibility line item, people need the story more than the spreadsheet. Once the story is good enough, nobody asks for the spreadsheet. That is precisely the mechanism of the empty report: frame present, filling absent, and the reader satisfied because the frame looks good. I do not believe interest in women's football will last if it is measured only through award-ceremony photographs.

10. Small samples and stories built from three matches

The annual season has a feature any data person must remember: few matches, many variables. Three matches is far too small a sample to conclude anything about playing style. But three matches is enough for public opinion to finish a story.

There is a widely observed effect in football: teams often improve briefly after a managerial change. Look only at the three matches after the change and you see a miracle. Look at the whole season and you usually see a return to the mean. Same data, two stories.

The same applies to a direct meeting between two relegation rivals. The result swings the points gap, and people call it a six-pointer. But the points gap is only one variable. The other is the fixture list for the next six rounds, which rarely reaches a headline because it carries no emotion.

Then come the international windows. Players return injured or exhausted, and the domestic league carries the cost. There is a name for the phenomenon. The point is that it is not mysterious: it is the product of overlapping calendars, and it is measurable before it happens. The six players past 2,800 minutes above are one example.

In every case just described, the empty report has a real-life version: a story with a complete frame, a complete climax, a complete cast, missing exactly the verification section.

The counter-intuitive angle

Everyone wants to blame the tool. I do not. A tool fills a gap only when someone asks it to. If a newsroom needs three pieces a day and only one real event exists, the other two must come from somewhere. The template is the cheapest route. The responsibility sits on the demand side, not the machine.

The industry's common fear is bad data. The more dangerous thing is absent data. A wrong metric can be caught by comparison. A well-framed blank cannot be caught, because it asserts nothing to catch. It merely looks finished. That is why I rank an empty report as more dangerous than an obviously wrong analysis.

I also check myself with one question: if the majority is right this time, will I dare to correct myself? Yes. I have corrected myself many times. In 2026 I thought a fatigue metric could forecast goals. After reviewing 64 matches I had to lower my expectation: it forecasts gaps, not goals. Gaps can be missed. That is the difference between a model and a prophecy.

Finally, emotion is not the enemy of data. Fans have emotions, and those emotions leave measurable traces: tickets sold, resale prices, comment volume against team quality, shirts sold after a stoppage-time winner. Treating emotion as a variable worth studying is far more useful than lecturing fans on how to think. Data is a mirror; the fool sees himself in it, the wise man sees the team.

Takeaway

From the next round, when you open a preview, do three small things. Count the traceable sources. Count the proper nouns. And look for blank cells. If an analysis has a full frame and no data, treat it like a dressing room with no players: neat, tidy, and empty.

I am 62 and have sat through five World Cups. Being 62 has not slowed me down; it has taught me which data is worth waiting for. When a report has nothing to say, the first person brave enough to leave it blank will be the most trustworthy person in the room. My question for the next round: does your newsroom have anyone brave enough to hand back a blank page?
