Is it time for the former Pac-8, then the Pac-10, to become a superconference and be the Pac-12? This model would be like the 12 member SEC, Big XII, and ACC.
The two universities to add would be Utah and BYU. I suggest these two as they are the only 2 universities in the west to not only have big time football, but also strong traditions in basketball, volleyball, gymnastics, etc.
I think adding these 2 universities would solidify the new Pac-12 as the premier western conference to equal the abovementioned superconferences.
