Oklahoma likely hosts Iowa State, West Virginia, and TCU...because those three hosted Oklahoma in '22 and the leaked TCU schedule has all legacy Big 12 opponents on the '23 schedule at the opposite venue as last year.
So, this means that Oklahoma will only host ONE of BYU, Houston, and UCF. So - assuming the leaked Oklahoma schedule is accurate - we have a 67% chance that we get the Sooners in Provo!
