Every SEC teams wins every game, even when they lose.
The ACC is 2-2 against the SEC. ATM and UofSC. Not bottom feeders (SC beat UGAy and got hosed a bit against awFL.)
With that balance, how can they honestly defend the bias? SEC teams always win, win or lose. If winning against UNC, that beat UoSC, that get UGAy means Clemson drops in the polls, the only way that UGAy stays top 10 is if they win when they lose.
