In response to the OP, Bubu is good enough that we might have been national champions last year if he hadn't switched off Craft in the NCAA tournament. If Bubu had stayed on him, as a guard who typically covers guys like Craft, he probably would have played him more closely and not backed off in anticipation of his drive. Thus, Craft's shot would have been more closely contested.
Granted this is only one play, but it was a biggee.
P.S. I'm not criticizing the switch as the wrong thing to do, but just acknowledging what might have been if he hadn't switched.
