There was a visitor on Sunday that hasn't been mentioned yet. I was told and have confirmed that Rockford OL Ben Braden (6'7", 295 lbs) was in Ann Arbor this past Sunday with his family.
The Michigan coaches extended Ben an offer and he was excited to receive it. I should have more from him later on, but he could be one to watch. He apparently also has offers from Wisconsin, MSU, and Syracuse.
Another name to keep an eye on is Illinois LB Antonio Morrison (6'3", 220 lbs). Morrison has offers from CMU, Illinois, Indiana, Minnesota, and WMU among others but is starting to gain more interest.
