ZERO downside with this worst case scenario:
Pie in the sky, best case scenario: Time goes by, the Big 10 expands, and they take Utah from the P10/P12/P14/B12.
Most realistic scenario: The P10/12/14 signs a deal with someone for around 30 million a year, give or take. The GOR expires in 2029/2030 so all teams can pitch themselves to whatever conference comes calling.
Worst case scenario: Utah goes to the B12 and is instantly the best football program there.
