Most of these decisions are made independently

Lots of elite recruits become close friends, and I'm sure they discuss playing together; but in the end, most players choose a school for their own reasons more than by who else is going. Personality fit with the rest of the team and the desire to play with other great players might cause friends to choose the same school; but academic considerations, coaching style, location's effect on family's ability to attend home games are examples of factors that vary significantly from one young woman to the next.

I don't put much stock in one choice affecting another unless there's a logjam consideration.
