To be honest, Cal's best days as a college coach are over. The last four years have a been a joke, especially for UK standards.
Will a change of scenery help become a better in game coach, help him diagram out of bounds plays, help him draw up end of half/end of game lays, prevent him from playing his favorites over other guys who should be playing? I doubt it, honestly. The guy is almost 70, he is what he is, and he ain't changing.
And I know you aren't predicting a 35-3 opening campaign for Cal, but his first yr at UK he had John Wall, Demarcus Cousins, Eric Bledsoe, and Patrick Patterson. Don't see anyone on Arky's roster that is close to those four. And yet Cal still managed to lose in the Elite 8 because he had no idea how to attack WVAs zone, so he let his guys shoot 4-32 from deep without coming up with any sort of adjustment to attack the zone.
