This according to CollegeBasketballTalk on NBC Sports:
While I would love for him to come back and anchor another Final Four run, I suspect he leaves. His dad seems to want him to go, and as a mid-1st round pick, I would not blame him for cashing in. He isn't going to graduate, so there seems limited upside to staying for another year.
On the other hand, this is an exceptionally strong draft. If he stays, he may be a sure fire lottery pick instead of on the border. Is that another to bring him back? Who knows. He also said that you only get to go to college once, but I feel like that reasoning only has so much pull.
