If he comes back he'd have the chance to lead an MSU team out of nowhere straight into the Sweet 16 and maybe further. We will be that talented next year if he comes back. If he leaves, he played a year for a team and didn't really impact the program the way a prime time player should. NBA guys will measure that. Unless he absolutely goes off down the stretch, it would be in his best long term interest to come back. 2nd round kids aren't even guaranteed to make a roster. If he's not slotted as a sure fire top 20 pick, it's a huge gamble to go unless he's ready to play overseas.

He has incredible talent, but he's got work to do before he's ready to be a 1 or a 2 in the nba. I do think his game will translate well to the nba but he's got to learn how to work his mid-range game, become an elite man up defender, work to earn his own shot, catch and shoot off the screen, etc...
