The Pac 12 expanded to 12 teams in 2011 and the North division has won all four championship games (two by Stanford and two by Oregon). But with USC, UCLA, Arizona, and Arizona State gaining strength, things could be much different in 2015.
Oregon and Standford are projected to once again battle for the North Division crown with Billingsley predicting Oregon to go on and win the conference title, but the Ducks may still miss out on the CFP. Oregon must travel to East Lansing in September and play their toughest conference game of the year against Arizona State in Tempe. Even a predicted revenge win in the Pac 12 championship game might not be enough to land a two loss Duck team in the top 4.
Arizona State may be the best shot the Pac 12 has to send a representative to the CFP this year. If they can get by Texas A&M in Houston opening weekend and beat UCLA on the road, then follow up with a win in the Pac 12 title game, a 13-0 Sun Devil team would be hard pressed to nose out of the playoff. But Billingsley is projecting Arizona State to fall on all 3 counts, leaving the Sun Devils with a very respectable 10-3 record.
