Makes sense to me:
1. I like Wojo and Collins, but wouldn't mind seeing some fresh faces on our staff, maybe someone who hasn't played or worked at Duke.
2. If K's eventual replacement will be someone from the Duke family (and it almost certainly will be IMO), I'd like for it to be someone who has had success as a head coach elsewhere. Wojo or Collins, if they go off and do well at 1 or 2 head coaching jobs elsewhere, would have strong credentials for the Duke job in time.
