I'm not concerned at all about him transferring. I'd be very surprised. Mooney and UR have done everything a guy could want as far as his developement and visibility. he's improved a ton in a short time and he's being noticed.
but I've always been concerned he'll leave to go pro early. he has the athleticism and the shot. this year he added a lot of strength. and his defense is getting much better. I personally think he could add more ball handling. if he stays he will.
but if he keeps up his play and is told he'll be a late 1st rounder, then you have to go. sometimes teams will offer a guaranteed multi year deal to 2nd rounders. if that's the case, I htink you still go. while I think we have talent next year, it's hard to predict we'll be as strong as this year. he'd have a lot to risk if he stays and we struggle.
