There's a little bit of gamesmanship going on here. The football signing period ended April 1. She's signing paperwork for a basketball scholarship since its late signing period started yesterday. However, if she plays football, that scholarship would count towards the football team's total, not basketball team's total.
I'm not sure the compiler of this list has actually been to these towns or knows what being a college town is. Los Angeles is a top college football town? Uh, what?
