If this were to happen I would like to see 4 divisions played similiar to the way it is done in the NFL
Northeast: Tennessee, Kentucky, Vanderbilt, Georgia
Southeast: South Carolina, Florida, Auburn, Alabama
Northwest: Oklahoma, Arkansas, Missouri, Texas A&M
Southwest: Ole Miss, LSU, Texas, Mississippi State
Every year you play your division (Kentucky Vanderbilt Georgia)
You play the team that finished the same in the division last year. (If Tennessee finished 1 they would play SE 1 Alabama, NW 1 Oklahoma, and SW 1 LSU)
Then we rotate our other 3 conferences games with 1 full division( If we played the Southeast it would be South Carolina, Florida, and Auburn
That would mean we played every team in the conference every 3 years and get the best matchups each year.
For example Tennessee's conference schedule would be Kentucky, Vanderbilt, Georgia, Alabama, Oklahoma, LSU, South Carolina, Florida, and Auburn.
If Tennessee finished 4th in their division last year and played the Northwest division on this rotation it would be more like Kentucky, Vanderbilt, Georgia, South Carolina, Arkansas, Miss St, Oklahoma, Missouri, Texas A&M
Take the top 2 at the end to put into the conference championship.
The alternative would be 7 division games with 2 rotating cross divisional games. It makes things easier, but I don't think it gets the best matchups for the fans year in and year out.
