All the SEC team rotations are set up on recurring rotations. The rotation set up does not change from year to year. There is no bias to favor any team. It is a very fair system. The SEC has many great rivalries that make for great TV games. The only thing that conference office does is to spread out the schedule so that there is the maximum number of excellent games each week. That is there will be no week where three or more excellent games are scheduled for that week. You can do that when you have a strong conference.
Playing 8 conference games instead of 9 in 14-team leagues means 7 fewer guaranteed losses.
It also means a given team is only playing 8 of the other 13 teams in the conference (not that 9 of 13 is much better). This is a reason super conferences suck.
Playing just 8 conference games in 7-team divisions also means you get seasons like 2012 where neither division champion (Georgia and Alabama) played any of the top 3 in the other division:
EAST
Georgia 12-2/7-1: Crossovers were vs. Ole Miss (3-5, W 37-10) and at Auburn (0-8, W 38-0); Lost at #6 South Carolina 7-35, Won vs. #3 Florida 17-9 (neutral site); Never played ranked teams in consecutive weeks, played two over a three-game/four-week span.
Florida 11-2/7-1: Crossovers were vs. #4 LSU (6-2, W 14-6) and at Texas A&M (6-2, W 20-7); Won vs. #9 South Carolina 44-11, Lost vs. #12 Georgia 9-17 (neutral site); Played three ranked opponents in four-week span (none in true road games) and four in a six-week span.
South Carolina 11-2/6-2: Crossovers were at #9 LSU (6-2, L 21-23) and vs. Arkansas (2-6 W 38-0); Won vs. Georgia 35-7, Lost at Florida 11-44; played three Top 10 teams in consecutive weeks, including the last two on the road.
WEST
Alabama 13-1/7-1: Crossovers were at Missouri (2-6, W 42-10) and at Tennessee (1-7, W 44-13), strange that they were both on the road; Won at #5 LSU 21-17, Lost vs. #15 Texas A&M 24-29; played three ranked opponents in consecutive weeks.
LSU 10-3/6-2: Crossovers were at #10 Florida (7-1, L 6-14) and vs. #3 South Carolina (6-2, W 23-21); Won at Texas A&M 24-19, Lost vs. Alabama 17-21; played FIVE consecutive ranked opponents, including three Top-10 teams in four games.
Texas A&M 11-2/6-2: Crossovers were vs. #24 Florida (7-1, L 17-20) and vs. Missouri (2-6, W 59-29); Lost vs. #6 LSU 19-24, Won at Alabama 29-24, played back-to-back ranked opponents twice (four ranked opponents in five weeks).
Crossover Records
EAST
Georgia: 2-0 vs. a combined 3-13 (Ole Miss and Auburn).
Florida: 2-0 vs. a combined 12-4 (LSU and A&M).
South Carolina: 1-1 vs. a combined 8-8 (LSU and Arkansas).
1-1 against each other.
WEST
Alabama: 2-0 vs. a combined 3-13 (Missouri and Tennessee).
LSU: 1-1 vs. a combined 13-3 (Florida and South Carolina).
Texas A&M: 1-1 vs. a combined 9-7 (Florida and Missouri).
1-1 against each other.
I'm sure it's a coincidence that the division winners happened to play the weakest crossover schedules Incidentally, the #2 team in each division happened to play the #2 AND #3 team in the other division.
If South Carolina plays someone more beatable than LSU as a crossover, there's a potential for a 3-way tie in the east without changing any division game results.
If Alabama plays someone that could challenge them as a crossover, there's a potential for a 3-way tie in the west without changing any division game results.
I don't know what the tiebreakers are after head-to-head, probably division record and then common crossover opponents, then like the Big 12 in 2007 where they had to go to the BCS to break the Texas-Oklahoma-Texas Tech tie.
Additionally, while Georgia beat Florida head to head, Florida played #9 South Carolina the week before playing #12 Georgia, while Georgia played Kentucky (0-8) the week before they played Florida.
I know, it's easy to pick outliers because they stick out. But that is something both conferences have in common: potential for crossover imbalance determining the division champions via non-common opponents.
