Basically Notre Dame is really making a push for Beyer, a four star DE/OLB from the state of Michigan. Beyer has always favored UM, but ND managed to get him down to South Bend for a junior day, and Beyer will be making another visit to ND after that too.
I'd still class UM as the favorite, after all his family loves UM, he's visited the campus plenty of times, and he'll also be at the spring game later this month. With some talented in-state players already committed away from Ann Arbor, it would be good land Beyer, who is rated the #3 player overall in the state, behind Lawrence Thomas (MSU commit), and DeAnthony Arnett (undecided).
A decision should come before his senior season...hopefully at the Spring game!
