They already floated the setup with Ross Dellenger. They took the conference winning % over the last 10 years. The top 8 played 2 of the other top 8 and 1 from the bottom 8, the bottom 8 play did the reverse. The only notable oddity was that Tennessee (after having an atrocious decade+) was in the bottom 8 (and at number 13 I might add) so Alabama is yelling about having to play the hardest schedule known to man. A few games might move around but I think this setup is the most likely.
