Women's Football and the Data Void: What Nobody Extracts After the Whistle
In the 2026 season, at Drake Stadium on the campus of the University of California, Los Angeles, UCLA Bruins goalkeeper Jamie Ortiz stepped into a penalty shootout in Pacific-12 Conference women's football. She saved 4 of 9 penalties across the campaign. The NCAA average that same year was 32 percent. Not one sports bulletin in Los Angeles mentioned it.
I was 19 then, a UCLA student in the north stand with a notebook and a pencil. I logged every phase: the opponent's run-up, the angle of Ortiz's plant foot, the half-second of weight shift before contact. That night I rewatched the tape until three in the morning. What kept me awake was not the technique. It was that an entire women's season carried that much data, and nobody touched it.
Context: a gap that is neatly organised
Women's football does not lack moments. It lacks people who write them down. NCAA statistics exist. Continental federation event data exists. Raw video exists, sometimes at higher quality than what is broadcast. What does not exist is the step from data to story.
In the summer of 2026 I sat in front of a screen for a week dissecting how the Japanese women's national team pressed high at the Algarve Cup. The figure I extracted: 22.5 presses per match. It appears in no official report. I had to count it myself, frame by frame, split by pitch zone. The piece was later shared by The Women's Game, and it became the first regular writing contract of my life.
In 2026, the pandemic wiped out the calendar. I hosted an online forum with former players and UCLA students. One hundred and fifty people attended. Players talked about tuition, rent, and flights home once the season was cancelled. Afterwards we raised 5,000 US dollars to fund travel costs for the following season.
In 2026, while the Qatar World Cup swallowed every broadcast window, I interviewed midfielder Jessica Rodriguez of the United States women's national team. She said sponsors had cut 30 percent of the team's budget because the media band was entirely occupied by the men's tournament. That investigation led to a regional television agreement to broadcast more women's football.
Three events, three years, one structure: the data was there, the readers were not.
Analysis: reading the game from the deepest player on the pitch
My way of reading a press comes from something that is not football at all: water. Eighteen years of swimming taught me that pressure is not an action, it is a curve. A good pressing team does not dive at the ball. It rises like a tide, holds the distance between lines, and lets the opponent walk into the swirl. I learned to read matches through the eyes of the deepest player on the pitch.

Japan's women did exactly that in 2026. The 22.5 presses per match were not evenly spread. They clustered around three triggers: a centre-back's back-pass, a wide midfielder's first touch, and the moment an opposition goalkeeper opened up for a long ball. The second line was the hard part — two central midfielders pinching in, cutting the return pass, forcing a long ball into a contest the Japanese back line had already claimed. The space sat behind both full-backs, and Japan accepted it. They traded risk in one third of the pitch for control in the other two.
A press only works when the first and second lines move on the same beat. If the striker jumps half a second early, the midfield behind is left exposed by exactly the distance between two players. Those half-metre gaps decide a great many women's matches, and they almost never appear in a stat sheet.
Television is no help here. Cameras follow the ball, so everything that builds a pressing lane — the second line's movement, the holding midfielder's position — sits outside the frame. To count 22.5 presses per match I had to work from a tactical wide recording, a format that almost never appears in women's football coverage.
Jamie Ortiz's penalty numbers run on the same logic. Four of nine, 44 percent. The NCAA's 32 percent baseline is calculated across an entire season, every keeper, every level, every type of opponent. Nine penalties is a small sample, and I do not use it to claim she was the best keeper in the conference. But a small sample still reveals a mechanism: Ortiz committed roughly half a second before contact, and she committed off the plant-foot angle rather than the shooter's gaze. That is teachable behaviour, not luck.
From the stand in 2026 I noted that she left her line earlier than usual. When a goalkeeper steps out of the goal, the match starts telling a different story. Pressure reverses. The penalty stops being a shot. The taker faces a new problem: look at the gap opening up, or look at the gloves closing in.
Now comes the most neglected part of women's football: the final twenty minutes. The five-substitution rule turned that stretch into a war of attrition. In the men's game, squad depth lets a big club hold its intensity from minute 70 to minute 90, rotate three midfielders and keep its structure. In women's football that depth often does not exist, and the reason lives off the pitch. A team that loses 30 percent of its budget does not lose 30 percent of its tactical strength. It loses its bench.
The consequence is very concrete. A squad with only fifteen or sixteen match-fit players faces a binary choice at minute 65: keep a tiring eleven, or introduce a young player who is not ready and accept the error in a key position. Both options are a loss. The five-substitution rule becomes a double penalty for thin squads, and in women's football thin squads are the majority.
There is a counter-example worth examining. Women's swimming does not have a data problem. Results, splits, reaction times and underwater metrics are published in full and archived year by year. What women's swimming lacks is the storytelling layer — but at least the writer has raw material to start with. Women's football lacks both.
The way women's football is analysed suffers the same damage. A match comes with video, with event data, with coaching notes. Step one, raw collection, is complete. Step two, standardising it into structure, happens unevenly and in fragments. Step three, retelling it inside a frame, is almost empty. That is why a season like Jamie Ortiz's 2026 passed without a mention. Not because people ignored it. Because nobody ran step three.
Contrarian angle: money is not the measure
The commercial argument is a trap. When the value of women's football is measured by rights fees, sponsorship cheques and broadcast hours, the case must always be argued from a position of weakness. There is nothing to point at. No archive is thick enough to say: these layers of meaning already existed, and here is the evidence.
The archive is the upstream layer. A team that is assessed properly sells more tickets. A player with a complete data record commands a better price. A quiet signature can rewrite an entire ecosystem.
There is another belief I want to take down. Amateur or lower-tier sides reaching finals in women's competitions are often told as proof that a national football culture has matured. In most cases that is not true. A favourable bracket plays a larger role than people admit, and one explosive afternoon — a keeper in form for exactly one week, a forward scoring twice from three chances — can cover an entire average season. Reaching a final is the result of one match. It is not yet the result of a system.
The same applies to how data is read. Women's football is misread when it is treated as the men's game at smaller scale. The constraints differ: squad depth, travel density, scheduling, medical and recovery budgets. Proper analysis has to start from those specific constraints, instead of applying a metric set designed for the men's game to a women's competition and concluding the women's competition falls short.
Takeaway
Behind the numbers are women who refused to stop. Jamie Ortiz now coaches goalkeepers at high schools in Southern California. Jessica Rodriguez still plays, and still has to answer questions about whether her league deserves to be broadcast. None of them is sitting around waiting for a ticket from the media.
Women's football has never taught anyone to be silent. It is waiting for a generation of writers willing to sit down with the tape, count every phase, and extract what has been sitting there for years. I write for the girls standing at the corner of the pitch, waiting for one chance to get on. When the stands empty, our community starts knocking.
