He has plenty of money, his Dad was what in the NBA for over a decade? He will be smarter than most when it comes to the NBA. You don't leave to go pro unless you are gonna cash in with guaranteed money, just is not a smart move. Lets revisit this at the end of January. Ill more than likely bet you he will come back if you would like.
Kind of a big question mark where he fits in the league. He is woefully undersized for a center position, and that's basically only position he can play. He also is so left hand dominant, that's a serious issue.... though that's gotten slightly better. He plays with high energy and is very solid shot blocker/ rebounder. But man, it's tough to find a spot in the league if you can't shoot. Good teams have even 5s that shoot from distance, now. Look at what Sabonis does for the Pacers, for example.
