I believe the BIGXII made $38 Mil per team while the PAC was making $32 Mil per team. So money would improve, especially since the BIGXII would capture a big media market in the west. And it's also not too much west where it would be a travel hindrance for teams already in the BIGXII and the Arizona schools.
The B1G made $55 mil per team and the SEC made $45 mil per team and the ACC made $34 mil per team.
I really do think that getting rid of West Virginia, adding Arizona schools, BYU and if they can rope Nebraska back to the conference would boost the profits per team close to what the SEC makes now, in the BIGXII.
