Especially this early in the rankings. You could make arguments against any 2-loss team to be out of the running. There are 11 teams ranked higher than OU, and you could make an argument against about half of them being higher than OU based on who they have played and who they have beaten
3-loss teams without a Conference Championships are going to need a miracle to get in. Sooners fans know they will have 3 losses when they get spanked by Bama and want to bitch about a team that won't have a head-to-head victory over them like the underwhelming UT team this year.
