Look again. gtsucks is right in that Bama, Auburn and LSU all play 7 home games, 1 neutral site game, and 4 road conference games. Due to the UF/uga game in Jacksonville every year, UF has their schedule set up for 7 home games every year. In 2018, they will have 4 home SEC games, 3 OOC home games with FSU on the road. In 2019, they get 3 SEC home games, uga in Jacksonville, and all 4 OOC games including FSU at home.
The common thread here, though, is that a lot of SEC teams only go on the road for conference games, rivalry games, or neutral site games; they don't/won't sign home & away deals anymore.
