The first domino was just pushed, too early to tell but big changes are coming.
The most likley scenario, IMO, is B1G grabs Oregon, UW, Stanford and Cal to make a west coast sweep.
Then the Big12 takes the best of the rest. Likely Utah, Colorado, and the Arizona schools.
In the unlikely scenario that UW and Oregon don’t leave, my guess is P12 raids B12. BYU might even be in the mix as the political ideologies of the west schools will take a back seat in order to survive.
Crazy times.
