If they're willing to trash Bama vs. State and LSU vs. State, two of the longest running "rivalries" in the SEC, I don't see why the SEC is beholden to the keeping other former SEC West matchups. Other than the sacred rivalries (Egg Bowl, Iron Bowl, UT-UA, Tex-A&M, Tex-OU, Fla-Ga, etc.) everything should be fair game.First off, whatever is decided initially should be taken with a grain of salt. It won’t last longer than 5 years, as there will definitely be more realignment before then.
But, I think we get OM, UK, Auburn. We’ll definitely get at least one traditional SEC West opponent besides OM. I think networks are going to want Bama-LSU as an annual game, meaning Bama has LSU, TN, Auburn as their 3. That should be fine with them since Auburn has been trash for the better part of a decade now.
Auburn needs a 3rd permanent on top of Bama / UGA, and it should also be a traditional West opponent. OM is out, they’ll have us, LSU, and probably Vandy. I think Ark, A&M, OU, and Texas are going to be paired up to take advantage of the SWC / Big 8 historical rivalries. Texas gets A&M, OU, and Arkansas. A&M gets Texas, LSU, and Arkansas. OU gets Arkansas, Texas, and possibly Missouri. Arkansas gets Texas, Texas A&M, and OU. They may swap some things around and give Mizzou another one of the southwest teams, maybe keep LSU and Ark as permanents, but the overall situation is that I don’t see any out of Texas, Texas A&M, LSU, Arkansas, or Oklahoma being available as a permanent opponent for Auburn. That leaves only MSU. Then also it makes sense to give us UK, as that game has been played almost every year in the modern SEC, and those are similar stature programs. Same w/ OM and Vandy.
If your matchup doesn't have a trophy or a recognizable nickname, it shouldn't be protected.
