Agreed this is definitely the best possible rival.
We can't have OSU as our top rival because the have Michigan, and vice versa
Iowa hasn't really had any success aainst us, so it'd b kinda like the Colorado thing all over again, except Iowa doesn't even have one title
Penn State has a history with us, a similar level prestige as us, and really no main top rival
Don't know for sure, but 1958 Iowa shared the national title or some such thing. One poster seemed pretty proud of it.
They finished second in both the AP and Coaches' Polls. They were, however, named the national champs by the Football Writers Association. But when people talk about national champions before the BCS, they refer to the AP and Coaches'Polls, so in 1958, LSU was the national champion. But Iowa likes to say that they won a national title. but we all know they didn't.
