Scouting

The women's basketball data gap

6 min read · ScoutRoom

Across 276 papers on athlete talent development, 9.42 percent were female-only. 60.14 percent were male-only. Of the studies that actually compared the sexes, 86.15 percent found real differences between them. That's the foundational finding behind why a men's scouting model, benchmark, or "best practice" cannot simply be handed to the women's game and trusted. The evidence is thin, and where it exists, it says the two games are not the same.

Why you can't just borrow the men's tool

Female athletes made up somewhere between 3 and 17 percent of participants across that research base. It's not that nobody has studied basketball performance, it's that almost none of it studied women, and the studies that did mostly found it mattered. A shooting benchmark, a load model, a talent-ID cutoff built on men's data and applied to a women's roster isn't a shortcut. It's an unvalidated guess wearing the credibility of someone else's evidence.

What's actually landed for the women's game

The real news is the gap is closing from a genuine research base, not just goodwill. A study of the Spanish women's top league, a decade of data, over 36,000 individual game records across nearly 3,900 games, coach-validated, sorted players into nine functional roles: slasher, floor general, three-point shooter, defensive anchor, and so on. It landed on nine roles independently of the equivalent men's clustering work, which also found nine. Two different research teams, two different sports, the same structure showing up on its own. That's not a coincidence you get from noise.

The single number that changes how you compare players

Buried in that same study is the stat with the most direct coaching application: normalising by minutes played, rather than comparing raw per-game numbers, raised players' measured performance values by an average of 23 percent. The reason is straightforward. Raw per-game stats systematically punish role players, and role players are most of any roster, over 43 percent of all players in that study sat in the two lowest-usage clusters alone. Compare two players on raw per-game numbers and you're quietly grading one of them on far fewer opportunities to produce. Normalise by minutes first. It's not optional, it's the difference between a fair comparison and a biased one.

The gap widened at the exact moment it started closing

In March 2024 the WNBA became the first US women's professional league with leaguewide 3D optical tracking, the same class of data the NBA has had since 2013. That's a real leap, and it will feed a wave of women's-specific spatial research over the next several years. But almost none of it reaches WNBL or NBL1. The reality at this level stayed box score and film, no tracking, even as the elite floor above it jumped. What did land at this level was footage. New league ownership and a broadcast deal in 2025 mean far more games are now watchable than two seasons ago, the single biggest practical upgrade available to a coach at this level, even without a single tracking camera behind it.

The gap is the opportunity

The women's, lower-league, single-camera level of the game is close to the least-studied condition in the entire research field. Everything richer describes a level almost nobody scouting NBL1 or a comparable league actually operates at. Nobody is going to hand a functional-role model down to this level built and ready to use. It has to be applied by hand, off box scores and film, normalised by minutes, benchmarked against women's data and never men's. That's more work than waiting for the tool to arrive. It's also available right now, to whoever decides to do it properly.
