Personally, in a perfect world, we'd get the two AZ schools, the Pac-12 would up and take Colorado State and BYU, and then we would have an 8 team playoff.
I like a 12 team conference, and I'd love to have Arizona and Arizona State. And BYU and Colorado State would give some natural rivals to CU and Utah.
I also think that the Big 12 and Pac 12 should pool their Tier 1 and Tier 2 media rights and create a lot of cross conference match-ups.
But, hey, what do I know?
