The same (old) win/loss rules apply within your division. You have to beat more teams in your division than any other team. If you look at the home division schedules as the one that counts the most, you can never have that dilemma. The best team in the West will still play the best team in the East.
The old rules with divisions was overall sec record, no delineation of specifically vs division record. If only division record matters go to a 7 game conference schedule because those other games are in no meaningful way different than any out of conference game.
THAT IS MY POINT... My schedule is a 2 Division SEC Conference with a Championship Game. That works with the same exact rules and format as before... before Sankey killed the 2 division system. The only thing that changes (the only difference) is the teams (four teams at a time) in each division rotate from division to division. And they return in the 4th year making it a 3-year rotation. I made an 8 and 9 SEC schedule game schedule for the Gators in all 3 years. And someone mentioned if we had, say... the west division champs with 3 losses, and they play the winner of the east that is undefeated. There could still be 2 or 3 other team in the east that are better than the west champs... but how often did that scenario every play out when we had 2 divisions in the past? Regardless of the divisions I don't remember if that ever happened.
