There are additions to the SEC where pods make a lot of sense. Oklahoma and Texas...I'm not sure that pods will end up being the best solution.
Adding OU and Texas means that there are 6 teams in our region (A&M, Texas, Oklahoma, LSU, Arkansas, and Missouri) which are difficult to divide into pods. Arkansas in particular should probably have and will likely want yearly games with Texas, A&M, Missouri, and LSU. A&M will want to keep an annual game with LSU. I presume that Texas and A&M and Texas and Oklahoma will be required games, etc.
Moving Alabama and Auburn to the East, Missouri to the West and eliminating cross division rivalry games is so simple, that I think the conservative SEC will do that rather than create a pod system. Both divisions would be pretty balanced on paper. It would solve the SEC's current scheduling issues that necessitate cross division rivalries (which currently primarily have to do with getting Tennessee-Alabama and Auburn-Georgia, and Arkansas-Missouri on the schedule every year.
Two 8 team divisions wont get every team playing every other team every two years, or hosting every four years, but it would make the cross division games more common than they are now, assuming the schedule will definitely go to 9 games. The negatives would probably mainly be related to splitting the Alabama and Mississippi schools from each other, but I have no idea how strongly those schools view those games.
