Just two weeks remain in the Pac-12 regular season, which means that the conference race has heated to its boiling point.  Oregon has regained control of the North after Stanford’s one-week interregnum at the top, but their positions could change again—and decisively—if the Ducks stumble this week.  In the South, Arizona State can clinch with a pivotal road victory in Pasadena, but otherwise three teams will remain in the hunt for that division as the final week approaches.
