I'm just afraid he's built a house of cards here in S'Ville. It's too early to make a call on Martin, Cuonzo.
Every coach has built a house of cards everywhere they go. Unless you prove that you can go to school after school and create a winner (i.e. Calipari, Pearl, Self, Pitino, etc.), you have potentially built a house of cards with your current job.
If Frank goes somewhere and doesn't have the same level of success he had here, they'll make excuses as to why he had success here and not there. If Tom Crean doesn't get it turned around at Indiana, it's because he built a house of cards. Same with Billy Clyde.
Unless you're searching for a top ten coach, every coach you hire is a crap shoot. If Cuonzo can recruit, he'd be as good of a candidate as any.
