Actually, I am a Michigan fan...
1...because they hate Ohio State
2...my Dad was a Mich grad who despised OSU and I had to be a Michigan fan (although I went to FSU). Dad has now passed on but watching the Maize and Blue during the season renews that bond that death really doesn't diminish. I miss the old man especially in the fall.
If your Dad hated Ohio State he was a true Michigan Man. Mine was a Ohio State guy, he is gone also. Glad to see he has someone to argue the 10 year war with up there.
As a conference the Big 10 is 174-98-5 against the ACC
The B-10 "big 3" against the ACC are as follows...
Ohio State 14-7 lifetime including 3 games with Fla. St. ('81, '82, '97) where they owned Ohio State.
Michigan 23-4 including 6 wins against Duke
Penn State 89-21 lifetime against the ACC although most of the games were before Penn St. joined the B-10.
All these stats are vs. teams currently both conferences. The source I used is college football warehouse.
