Now that every school is finished with spring practice, here's an updated look at how the Pac-12 power rankings will look in 2017:
1. USC: The Trojans will enter the 2017 with the nation’s second-longest winning streak (nine) and the Heisman Trophy favorite at quarterback in Sam Darnold. The spring saw the emergence of several talented young receivers, but injury problems on the offensive line are a concern.
2. Washington: After winning the Pac-12 and advancing to the College Football Playoff, the Huskies appear on track to be a national power for years under coach Chris Petersen.
