Maybe. Mississippi is playing them because Wake backed out on a game. The series was scheduled in Oct. 2024, after PAC-10 had fallen apart. SEC gave Mississippi a waiver (same as they did for Tennessee counting Wyoming as a P4 game when Michigan backed out on them). I think we'd need a waiver, and don't know if SEC would give it 6 years out.
More I think about it, I agree. Scrap Troy for 26 & 27 and tell Memphis we're not playing there in 29, we can either go to Memphis in 27 or we'll scrap that series too. I suspect they'll find room to play us in 27.
