Auburn was really lucky to finish 6-2 in the SEC. In 2007, don't be surprised if Auburn finishes 4-4.
As for the East, yeah, it's the hardest division in football to predict. After looking at a large range of variables, Florida, Georgia, and Tennessee are all DOWN on paper, and S. Carolina is UP, but only a little bit.
Kentucky will come back to earth. They had a miracle 2006 season and lose 4 OL starters.
The West is also strange. LSU lost a ton to the draft, had some close wins, but were the most talented club in the conference. Arkansas loses a ton to the draft, but that's it. Auburn lost a lot, had a misleading record, and was incredibly lucky. Alabama is one of only two teams in the conference where everything is looking up: few losses to the draft, unlucky 2006, and actually performed well outside of the red zone. Do YOU really think Nick Saban will allow that to continue.
Each division is 4 teams deep, and if Kentucky continues the miracle, the East is 5 teams deep.
