re: Old School Model - Rose Bowl Edition : #1 Michigan (13-0) vs #4 Alabama (12-1)

I didn’t watch much Big 10 football this season (got busy around the house watching some paint dry) so maybe I’m wrong but I don’t remember many Big 10 teams playing quality OOC teams. I remember tOSU beating ND in South Bend which was decent. What other games did Big 10 have OOC where we could get a sense of that conference’s strength relative to other conferences? Feels like they just played each other all year so nobody knows how good they are/how good Michigan is.
