and B12 champ (whether it's Colorado, ASU, or BYU) will have to host a 1st-round game in the CFP.

Although I think it would be a great game, I'd hate a B12 CCG with Colorado and ASU for 2 reasons:

1. Because it wouldn't include BYU.
2. Because Utah fans would come out of the woodwork to sing the praises of the former P12 and use that as an indication that the B12 really is beneath them.
