Lately I've decided we need to have a multiverse, so a player can go to various different colleges in alternate dimensions or realities, and then we can really see the difference in development of a player based on coaching.
Since that probably isn't a possibility, I'm pretty sure if Bonnie or Karlie S. had gone to UConn, they would not have been as good as Katie Lou. It wasn't just because they didn't play for Geno. Conversely if KLS had gone to Stanford she still would've ended up the best of the 3. But again, if only we had a dang multiverse to play with, then we could know some of these things for sure.
