Like any talented, powerful person, Cal is constantly tugged in different directions to do different things.
Coach K has flirted with the NBA as well. And there is no question that K's game slipped a couple of notches about a decade ago.
But K satisfied his itch through an affiliation with USA Basketball. Probably not coincidentally, he has gone through a resurgence of late.
No telling what Cal will do. Life is short, and he is no doubt measuring how he can have the most impact - get the most done - in his remaining years.
There is a strong and valid argument that he can have no greater impact than he is enjoying under his current platform.
But you could say the same about Pat Riley when he was coaching the Lakers, and to a lesser degree, the Knicks. Now Riley has had arguably as much success as an executive as he did as a coach.
There is no question that Cal is looking at some other nearby mountains and wondering if can climb them. Wondering if he should try. That spirit is what makes guys like Cal great in the first place.
