The idea is to make it harder for two SEC teams to meet in the CFP title game. Using my proposed format, one of the teams would have to be Missouri, which as a Midwestern school according to the US Census Bureau would compete for one CFP title game berth alongside other teams from outside the South as defined by the USCB. Any of the remaining 15 SEC teams could then be Missouri’s opponent in the CFP title game, provided they go that far.

Using the USCB region definitions, each of the other P4 conferences has the following member distribution among Southern and non-Southern states:

ACC:
Non-Southern (5): Boston College, California, Pittsburgh, Stanford, Syracuse
Southern (12): Clemson, Duke, Florida State, Georgia Tech, Louisville, Miami (FL), North Carolina, NC State, SMU, Virginia, Virginia Tech, Wake Forest

Big Ten:
Non-Southern (17): Illinois, Indiana, Iowa, Michigan, Michigan State, Minnesota, Nebraska, Northwestern, Ohio State, Oregon, Penn State, Purdue, Rutgers, UCLA, USC, Washington, Wisconsin
Southern (1): Maryland

Big 12:
Non-Southern (9): Arizona, Arizona State, BYU, Cincinnati, Colorado, Iowa State, Kansas, Kansas State, Utah
Southern (7): Baylor, Houston, Oklahoma State, TCU, Texas Tech, UCF, West Virginia

The lone Power FBS independent school, Notre Dame, is non-Southern (Midwest).

So, here’s the amount of possible title game matches between same-conference schools based on my proposed format:

Big 12: 63
ACC: 60
Big Ten: 17
SEC: 15

Total: 155

So the other points behind this is to make a Southern team have to go through a non-Southern team every time if they want the CFP title so bad, and to make it harder for two teams from the same conference to meet in the CFP title game.
