I can't imagine the 4 corners all going to the Big12 and UO and UW standing pat.While money and stability almost certainly drove this, I do think that distribution uncertainty was a factor. When you're an Athletic Department which has to recruit nationally, it's vital that your games are accessible for HS players, potential college transfers and parents / influencers across the country. The Big 12 could promise that and verify it while the Pac-12 was still saying to be patient and hope / trust.
That same dynamic applies to Oregon, so the Ducks being on the move is something I'm expecting.
The ducks are either going to beg the B1G and go with a reduced payout or they are going to jump the line for the Big12
