I like no divisions too. Three permanent opponents: Auburn, Tennessee, LSU?
If we do pods, then
W1
Arkansas
Missouri
Oklahoma
Texas
W2
LSU
Ole Miss
Mississippi State
Texas A&M
E1
Alabama
Auburn
Tennessee
Vanderbilt
E2
Florida
Georgia
Kentucky
South Carolina
Keep traditional rivalries as much as possible so nine SEC games a year, ie Alabama/LSU, Auburn/Georgia, Florida/Tennessee.
Or, play three teams from your own pod, and two teams from other geographical division pod, one team permanently, and one team each from other two geographical pods.
Ie Bama plays Auburn, Tennessee, Vanderbilt, Florida, Georgia, LSU, State, Texas in one year. Rotate Florida, Georgia, State, and Texas out in following year.
