I'm sticking with BU. They've been getting the best recruits of any program recently. Michigan's reign is mostly over, if you look at commitments for future years and not past years. BC had that one great year, but otherwise hasn't really been that potent with recruiting recently. Minnesota is always going to be a big pull, but he's probably staying in the North East, so I doubt Eiserman will be able to convince him.
Maybe Michigan State, if you wanted an underdog. They've been recruiting as well or arguably better than Michigan the last few classes.
If you wanted to go very left-field, North Dakota's class for 2006 born players is very strong (they added another NTDP player a few days ago from Hagens' NTDP class), and it's probably one of the only schools where his brother would get a significant role too. If Michael goes to BU or somewhere like that, is he really going to play until his junior or senior year?
