Being a life-long, diehard UK fan and living just south of Rupp Arena, you hear from wayer boys, managers, classmates, players, etc...
With that said, Calipari was so successful with Cuz for three reasons: trust, expectations and John Wall.
Cal did a good job of saying "Cuz, this is your team. We win and lose because of you. We go as far as you take us, etc..." He meant it too.
John Wall meanwhile was the true leader of the team. He was not afraid to pull Cuz aside and tell him to cool his crap, calm down, run to your spot, play D, etc... Cuz has not had that since he left Lexington.
