2015 Pac-12 preview: Is this college football's new toughest conference?

Is the Pac-12 the best conference in the country? That’s the question college football observers are asking more and more these days. The default rebuttal from SEC partisans is that the West Coast-based conference has not claimed a national title in the last decade, but Oregon and USC may be the two strongest candidates to put an end to the streak this year. The Pac-12 also features several other teams with the potential to make a run at a College Football Playoff berth. Expect a heated race in both the North and South divisions, with lots of upsets along the way and some thrilling installments of #Pac12AfterDark.
