It depends on the conference. With the B1G and the SEC estimated at $110 million plus starting at 2027 after the CFP is redone, not really. ND would. Oregon, Clemson, UNC, and FSU might but probably not.
As for the B12 and PAC, totally different scenarios. The B12 is supposed to be around $50 million after OU and TX leave. Easier to get to $50 million if you have a shot at the CFP. BYU, Cincy, and others brought that to the table. Oregon, and Washington definitely would bring enough to the B12. Not sure about Utah and Colo and the Arizona schools, but thinking that would destroy the PAC and that would be good for the B12.
