A Penn State win over Ohio State would have made things interesting. It sounds like that with records against crossover teams being the tie breaker, if Penn State had won out the rest of the way Michigan likely would have won a 3-way tiebreaker if Michigan, Ohio State, and Penn St all ended up with 1 loss. Imagine that - Michigan goes into Columbus 11-0 and loses, but then wins the Big 10 championship game the following week. Michigan as a 1-loss Big 10 champion would have been hard to keep out, provided the Ohio St loss wasn't a blowout.
