You have to take into account the whole conference and what game they may want/need. Au is 100% given. Tennessee and LSU are not. Tennessee should get UF, Vandy, and Bama, but it is just as possible that they get UF, UGA, and Vandy. LSU may get the Mississippi teams and A&M. When you have to get everyone in teh conference to 3 yearly rivals things sometimes look odder than you would think.
Would be a fun project for this forum to schedule out all SEC teams, including Texas and Oklahoma. Trying to maintain some rivalries below, but still looks off and I went with geography the best I could.
Texas - Oklahoma, Texas A&M, and Arkansas
Oklahoma - Texas, Arkansas, and Missouri
Alabama - Auburn, LSU, and Ole Miss
Auburn - Alabama, Georgia, Mississippi State
LSU - Alabama, Texas A&M, Florida
Arkansas - Texas, Missouri, Vanderbilt
Ole Miss - Mississippi State, Alabama, Vanderbilt
Mississippi State - Ole Miss, Vanderbilt, Florida
Texas A&M - Texas, LSU, Kentucky
Georgia - Auburn, Florida, Tennessee
Florida - Georgia, LSU, Mississippi State
Missouri - Oklahoma, Arkansas, Tennessee
Tennessee - Missouri, Georgia, Kentucky
Kentucky - Tennessee, Texas A&M, South Carolina
Vanderbilt - Mississippi State, Ole Miss, Arkansas
South Carolina - Kentucky, ?, ?
