Taking OU and Texas by the SEC is the first step in one gigantic league, run by the SEC / ESPN. It may not be soon but they'll next try to grab the top ACC teams such as Florida State, Clemson, North Carolina, Miami, Virginia, and Syracuse. Having the ACC under ESPN will help this grab. And maybe before that, they will work on taking the top teams from the Pac-12. Finally, there is one conference left - the Big 10. At this point, the SEC / ESPN has the entire nation blanketed except the Midwest. The SEC will have their own college football playoff. The Big 10 will be shut out and the top powers (Michigan, Ohio State, Wisconsin, Penn State) will be forced to join this super league - with ESPN owning all the inventory and Fox shut out.
This ploy is similar to what happened in Europe a couple months ago where all the top teams from different leagues banded together to try to form a super league. Luckily, the players and the fans were were against this and it didn't happen. Well, I don't see the players caring and they don't have the power. The fans are too sensitive about being left out that they will go along with it.
ESPN might want that, but there are two issues. One is that the have to compete against Fox or any other network. Fox isn't going to just roll over. Two, The B1G isn't going to just roll over either. The last thing they would want would be to negotiate from a position of weakness. They want and need competition for bidding rights otherwise ESPN won't have to offer as much. I would expect them to side with the PAC12 or whoever is left to build their own coalition.
The desire to ditch the NCAA should begin to wane with NIL. But if the majority still want to bail, they don't need to merge into one or two large super groups to do so.
