There were bound to be some repeats and the SEC front office warned of such.
Outside of the 3 perma-rivals, for Texas, the 2025-2026 repeats are Florida and Miss State. But they did manage to keep up with the home/away so nobody has to play an away game twice in a row.
The same can't be said for the perma-rivals. Since for some idiotic reason they already had Texas A&M and Arkansas either both away, or both home, in 2024/2025, it was inevitable they were going to have to switch one in 2026. Arkansas is the lucky winner who will have to play in Austin two years in a row.
TX-OU is of course a neutral site game so no issues there.
