I wouldn't be surprised if there is not a least a realignment of the East/West SEC conferences to even out the competition once Texas and Oklahoma come over.
I read somewhere there is already talk NCAA wide of doing away with split conferences and conference championships all together and declaring a number 1 and 2 within the conference based on record. That way every conference sends 2 to the playoffs and the CFP then picks the additional 2 to round out the 12 teams.
Divisions are going away. From what I heard it’s gonna be 3 permanent rivals for each team then the other 12 teams rotate every year so you play every home and away once every 4 years. Top 2 teams play in Atlanta.
