Gameday won't be in Oxford for Bama unless both teams are 5-0 and unless Florida or LSU lose early. Florida-LSU in Baton Rouge is the same weekend of the Ole Miss-Bama game this fall. So unless the Ole Miss-Bama game is somehow significantly more attractive, they'll be in Baton Rouge that weekend, especially with LSU being a pre-season Top 10 and Florida being the national title favorite.
In 2003, when we played LSU, they'd have been in Oxford if Purdue had beaten Ohio State the previous week in overtime. Instead, Ohio State held on making the OSU-Michigan game effectively the Big 10 title game that year. So, they went to that game instead.
