US girls’ high school basketball, with extra depth on Central Texas (UIL classifications, the Austin-Round Rock corridor). Where the careers actually start — recruiting, AAU pipeline, top programs, the players whose names will be in WNBA drafts in five years.
Pipeline math: high school → D1 college (NCAAW) → pro leagues (hoopwomen.com). We track the first two; pro coverage moves to the sister site.
