It has been mentioned previously, but SEC teams also get propped up higher for playing each other. They claim they are the best and preseason ESPN polls agree, so they are penalized less for losing to each other and get more street cred for beating each other. So, the losers of their conference games remain highly ranked because they lost to another "great" SEC team and the winners of the games immediately get thrust to top 5 because they beat the almighty SEC team. So, when a number 20 Ole Miss beats a number 1 Alabama, Ole Miss jumps up to top 5 while Alabama stays in the Top 10, because their only loss is to the top 5 Ole Miss juggernaut. It is a circular argument and the 2014 TCU team proved it in the Peach Bowl.
