A couple of Michigan players mentioned, but the kid I want most from there is Caris Levert. Probably isn't going to come out for another year, but he's a definite sleeper type player if he does. Was a 6'2" pg entering his senior year of high school, and now is 6'7" and reportedly still growing in his sophomore year. Last year he didn't play much, but this year he's arguably been michigan's best player. Is unequivocally their best defender (is a nightmare against point guards with his wingspan) and has become much more of a playmaker on offense (runs the point sometimes) and can shoot the three. He still needs to put on a little weight/strength for the NBA, as happens when a kid grows 6 inches in two years, but he has the ability to be a quality two-way player in the NBA, and maybe even better if he keeps improving growing.
Again, probably not coming out until 2015 because of the depth of the class and his late-bloomer status, but definitely someone to watch, and worth a pick in the low 20's.
Also, I love McGary (who's Hansborough with better passing and worse free-throw shooting), but he's got worse back issue than Sully it sounds like. I also don't think he can really play center in the NBA, and we don't need any more 4s. He'd be a good reserve while on his rookie deal as a big who can give you a spark off the bench for 15 minutes a game, but he's probably not someone who will be a franchise cornerstone. Makes me sad, too, because I love with how much passion he plays.
