With signing day in the books, here's an updated look at how the Pac-12 power rankings will look in 2017:
1. USC: USC already sat atop these rankings the last time we did them and proceeded to bring in the Pac-12's top-ranked class. There is early-impact talent, but it will be tough for any true freshmen to earn early playing time.
2. Washington: The Huskies remain the favorite in the Pac-12 North after signing the nation's No. 23-ranked class.
3. Stanford: This class was rare for Stanford in that it brought in several players who could help right away.
