Actually, Oklahoma WAS in the running in 1978 when that happened.That is potentially the case this year. And even in the not too distant past, Nebraska and Oklahoma rematched in a bowl although I don't think either was in the running for the NC when the Orange Bowl was played.
Oklahoma got 5 votes in the coaches poll.
We got the same number as USC.
The votes for them cost us a consensus (the AP went with us, 38-19).
