I saw this on ESPN's Rumer Control, but apparently Michigan has offered IN PF Mitch McGary their open 2011 scholarship (and I am assuming this means he also has a 2012 offer in case he stays in high school for his senior year) that was open up from Morris going pro. UConn is also offering a scholarship for the 2011 class.
McGary is a big time prospect, rated the #1 PF and 4th overall from ESPN for the 2012 class. There is the potential that he can join the 2011 class if he so wishes (not quite sure how that would work, but he can if he wants to). While it is a possibility, the chances of happening are not too high as his high school coach does expect him back for next year, but with 17 year old kids, this can change in a hurry.
He does have a Michigan connection as his AAU teammate is Glenn Robinson III, who is committed to the Wolverines for the 2012 class.
