Brad Stevens would be as scary a hire as I can think of. He's a brilliant guy who'd have even more appeal with recruits after time in the NBA. He'd also probably, at that point, realize he's a college coach (as another poster mentioned) and wouldn't be looking to leave anytime soon. He wouldn't need much time to start assembling an impressive roster if one was needed. If his time with the Celtics didn't go well, he may also be looking for a spot with less intensive media pressure which would make Gainesville attractive relative to other options he'd certainly have. Why not Fred Hoiberg or Tony Bennett though? I really like both of them, especially Hoiberg.
