Sorry if this was covered elsewhere but it looks like the biggest shakeup with regards to Conference realignment (OU and UT to SEC) wont happen until at least 2024.

This will make things somewhat interesting, as Cincy, Houston, UCF and BYU are set to join the Big12 in 2023. So it seems we may be seeing Texas and/or OU take on Fickell, Malzahn, and the fighting mormons.

Based on some of the reports Ive heard about OU and Texas, Texas has the money to pay the conference exit fee (shocker, I know) but Oklahoma currently does not. And Texas isnt exactly in a hurry to play in the SEC just yet.
