In terms of attractiveness in the Pac12 USC, Oregon, Stanford, and UCLA
Are the most in demand.
ASU, Arizona and Washington are at the next level and then you have the Utah's and Wazzou's.
Utah looks a bit better right now because of its record/ranking, but generally speaking, if bowls have choices of Pac12 teams, USC generally doesn't drop out of the top 4 when they are ranked.
