Yes, some misinformation in this thread. The only realistic way we don't make the conference championship prior to today was if Baylor and/or ISU win out and we lose to OU. In that hypothetical situation, we'd lose the tiebreaker to ISU and have one more loss than Baylor. Since Baylor lost today, we effectively* don't have to worry about them. An ISU loss to Texas also knocks ISU out of contention.
If both teams beat OU, OU would have 2 losses, but we wouldn't have the tiebreaker with OU, either!
