Auburn and Texas AM are both in the SEC, and I think both of them would get absolutely stomped by Washington. I don't even think LSU could beat them. I don't think SEC teams are de facto better than anyone.
I think Bama and Georgia are good, not because they are in the SEC, but because Georgia stomped FSU by fifty points and Bama took Michigan to OT (after beating Georgia). Both teams are well coached with stacked rosters, and they seemed to get better as the season progressed.
