To add to Mdot, other guys that impressed:
JT Tuimoloa - Ohio state was able to get sustained pass pressure because of him. Disruptive. Great against run.
Ohio State's DT - One of the DT's played a whale of a game. Had the lone sack and plugged inside run until Michigan started exhausting them in the 4th. Even then though, the running lanes that were opening were coming from under Center and were handoffs working to the edge.
All the TE's - Stover, Loveland, and Barner all are fantastic. Barner more of a blocker, but all were impressive.
Igbinosun & Sainristl - I know Burke and Johnson were the guys everyone in the NFL has their eyes on. Igbinosun is a guy Michigan wanted very badly in the portal last year from Ole Miss. He's a physical corner. Sainristl was all over the field again. And they put him over Harrison when Johnson got hurt. Quite the transition from slot WR to where he is now.
