As Pollard stated, "this is going to take time, and we need patients", its as simple as that. If anyone thinks that something on expansion is going to happen quickly they are only fooling themselves. Until the Pac 12 and Big 10 redo their media contracts nothing is going to happen. Why would they expand now without know if it is worth them to do so, because it helps teams from the Big 12? Not going to happen that way.
The remaining 8 schools right now are fine, and will stay that way for at least 2 more seasons, and most likely four more. If OUT leave after the 2022/23 season then they will both have to buy out the media rights for the last 2 years at $75 million for each school. I really cannot see them leaving them, because ESPN does not control the rights until 2024, why help out the ratings for CBS? If they leave before the 2024 season, then they will have to pay only $75 million between the two schools.
ISU and OSU are too valuable not be picked up by another conference and maybe others but those two schools will be fine. WV and Baylor are the schools that could be on the outside looking in when this is all said and done.
