Like many of you, I am not a fan of the Pac 12.
However, there is one scenario that could potentially get BYU into a major conference.

I assume the big 12 will cease to exist.

Could the Pac 12 take the 10 teams in Oregon, Washington, California, and Arizona and form the pack 12 West.

Then the Pac 12 could pick up seven of the remaining big 12 teams, add those teams to Utah Colorado and have BYU join the conference. This assumes that West Virginia with leave for the ACC or another conference.

This would be a 20 team Pac 12/Pac 20.

However, I am afraid BYU will be left out because of politics/religion.
