Watch CM and PM and tell me their shooting form development was good. The transfer portal is one of the best things to ever happen to college sport, especially the players. No more will coaches have leverage over players when the coaches are abusive. Think about the positive changes Iowa football has had to undergo.
About fans, fandom is already shrinking. Not a big deal. Fran may not change how he interacts with refs, but I can guarantee, he will be less likely to act out on players. Think about Izzo. Dude will never grab another player again.
We already have a broken system. Teams like KU and Duke had a strangle hold. I personally like now that they don't.
