It seems like this happens a lot too.
Both teams do usually play that late FCS matchup the same week and right before the IB but you are 100% correct they prepare for Us with that time.
In this case though yeah they will have been preparing for us for 3 weeks straight.
Auburn Off Week Before Playing Alabama History (Modern Era 1948-2025)
Alabama Result
Both teams had AT LEAST ONE week off prior to the Iron Bowl every year from 1964-1972, 1974-77,1979-82, 1984-1992. Auburn had TWO WEEKS off in 1966. Both teams were also off in 2008, which Alabama won. In those 27 games, Alabama leads, 19-8.
I will exclude 2020 because teams had unplanned weeks off due to positive Covid tests.
1973 - Alabama played #7 LSU on Thanksgiving Day while Auburn was off, W
1978 - Alabama had two weeks off, Auburn one, W
(Alabama and Nebraska had originally been scheduled to play each other on November 25. But Nebraska didn't want to face Alabama right after playing Oklahoma and Mizzou (8-4 Liberty Bowl winners that year who beat Notre Dame, Nebraska, and put up a fight with Alabama), so when ABC offered both teams a prime time Saturday slot to open the year, they took it. Nebraska's entire schedule was a three-game season and they didn't want to play all 3 in 3 weeks. Good thing since both of their losses in the regular season were those two teams).
1983 - Auburn had two weeks off, Alabama played on the road at #15 Boston College, L
Teams not having the week off prior to the Iron Bowl appears to have really begun with SEC expansion in 1992. In fact, there were complaints about how it was unfair that Alabama's schedule (and other West teams, but Alabama was the one usually winning) had a built-in week off prior to the SECCG in 1993-99 while Florida had to face powerful FSU and the SECCG back-to-back in 1992-96, which resulted in that game being moved up a week.
2000 - Auburn had off week, Alabama played Mississippi State, who was pretty good back then, L
2007 - Auburn off week, Alabama was busy throwing the game to ULM, L
2009 - Auburn off week, Alabama played UTC, Strug-gle WIN
2010 - Auburn off week, Alabama moved up Ga State game, L
2013 - Auburn off week, Alabama played UTC, L
Now.....there's no way we were going to beat them in 2000, but the other games here are quite interesting. I remain convinced the best thing that ever happened for Auburn in 2013 was they had a week to come down from the Georgia miracle before facing us.
But note for the record that 2 of Auburn's 4 most recent triumphs against us occurred with rest advantage.
