I don't know, will it really?
The Big ten was already making a lot more than Big 12. Their basketball totally sucks compared to the Big 12 (as does everybody else except for Big East). Ohio State has been the best program in either conference in football but Baylor, OK St and TCU have all done just as much as Michigan and Penn State, actually more. Then after those top teams the Big 12 is kind of objectively deeper in the middle and bottom.
No amount of money is going to make Minnesota, Rutgers, Purdue, Illinois, Maryland, NW and Indiana into Texas-based or Florida-based football teams.
SEC is a different animal, they have a path to utterly crush all other leagues in football including Big Ten.
