re: How did the 12 SEC teams agree on these East & West permanent rivals for over a decade?

You gotta remember that in 1990 when the divisions were put together, Florida was hovering just above .500 all time and coming off a 6-6 record i 1989. . the thought of Florida winning a national title was about like Ole Miss winning one. Auburn was a much stronger program. and the two had played forever. Certain teams weren't anything like they are today. Most people thought Arkie would come in and be a championship contender most years as they had been in the SWC.
