It's been rumored for a while that Green and Collins would follow Holly if she was fired.
Honestly, exodus from the program after a coach is fired is just part of the solution. It's painful but it is what it is. And it's gotten so bad that it's going to happen either way because some players want to play for her (the younger ones who are still naive) and some don't, so there will likely be exodus either way.
And yes, players with problematic parents like Westbrook's typically never work out for a program. Hayes' and Cooper's parents were problematic, too, although in the end they weren't the cause of them leaving.
TBH, I'm shocked Westbrook ever picked here. She would've been an AA at a school that actually runs a real offense, like Oregon or ND, who were on her final list. Not to mention, had she picked ND she would have a NC ring.
