The point is, PAC 12 comes up first on the TV rights deal. Big 12 is making more, and with Tier 3, a lot more. If that is still the case in 2023, then why not look at making a lot more money?
The Big 12 rights deal probably still has the increase in pay for adding schools, and Fox/ESPN, would know who the big boys are. Why not try to get the big players all together?
