The SEC split into divisions in 1992.
There have been 7 seasons where the West champion had 2 losses, and 2 other seasons where they had more than 2 losses. This does NOT include the couple of times that the "champ" was ineligible due to sanctions so a 2nd place team played:
93 (Bama 5-2-1)
95
96
97
98
00
01 (LSU 5-3)
02
07
LSU in 2007 was the last 2 loss team to win the Division
