which seems likely considering that he is projected to get drafted at top 10. Michigan will lose their entire starting OL. Fitzgerald Toussaint is an unknown factor because of his gruesome injury and the RB is a huge question mark considering that they have a lot of trouble running this season. Luckily, they have Devin returning with starting experience.
On defense, they return players with experience, but no true pass rusher. Frank Clark have the potential, but haven't showed it yet. Losing Kovac hurts from the leadership standpoint, but they are replacing him with a better athlete at S. The CBs aren't terrible, but they're not great either. One must step up and become a true #1 CB, but we won't know until next season so secondary is still a concern. I expect the defense to be solid which won't be a concern with Mattison at DC.
Michigan have not beat anybody great and their best win is NW in which they were lucky to win thanks to Roundtree's miracle catch. However, they lost to every team who are good(not sure Nebraska would qualify as good). They have a pretty tough schedule with NW on the road, ND coming home(but Golson should improve and return key starters from a tough defense), PSU on the road, MSU on the road because of their defense, and OSU at home.
