In seed order Georgia, Texas, Michigan, Alabama.
Georgia, duh. Their toughest game before the SEC championship game is Tennessee. Two time champ, they are a lock even if they go 12-1 and don't win the conference. It's difficult to contrive a scenario where they don't get in.
Texas. We will be favored in every game except 1 and its an out of conference game against one of the all time great programs who is still in the midst of probably the most dominant run in the BCS/CFP era. We've underachieved for over a decade but this is the strongest roster since 2009 where we were one of the two best teams in the country. I think we are one of the four best this year.
Michigan. Easy-ish schedule, a couple of tough games Penn State (road) and Ohio State (home). After that they are probably double digit favorites in every game.
Alabama. I do think Saban still has it. I absolutely think he would rather have a great QB than have to play bully ball and try to win with a ground game and a defense but he is gonna try and make do with what he has and I like that approach rather than morons trying to run their 'systems' with whatever guys happen to be on the roster. SEC West is still tough though and this is the seed I have the least confidence in just because of their road to get there.
