I honestly think there will be 7 teams 6-2, one way or another.
I think Tennessee, Georgia, Alabama, Texas, get bids. Ole Miss, Texas A&M and LSU out of playoff. This is assuming a Texas win vs. TAMU. If TAMU wins they are in and Texas is out. (Assuming a loss at Arkansas). Other scenario is Texas wins at Arky and loses at Aggie. Aggies play Bama in title game...lose and now we have Bama (in) and 6 teams at 6-2. I think Texas A&M gets the bid because they beat Texas and played in the title game. LSU, Georgia, Texas get the other bids. Tennessee and Ole Miss are out.
It will probably be a complete mess. But when you play an unbalanced schedule, this is what you can expect.
