I don't know.
Arizona's roster is at least as good as the Zags. If he couldn't find a suitable role at Gonzaga, why would he go to Arizona? And why would they want him for anything other than to come off the bench? His production for 2 years was underwhelming. Plus, what's the Arizona coach's pitch? "My buddy Mark Few doesn't evaluate talent right, but I can see that you're a star waiting to happen."
My advice to him would be to go to a lower-level program where he's certain he can play. I have a suggestion, but then it might seem like I'm biased.
