The top four of the Power Rankings stays exactly the same as Virginia, Cal Poly, Oregon State and Louisiana all kept up their end of the bargain. But beyond that, TCU's stunning sweep at Texas and UCF's 2-1 series over Louisville shook up the remainder of the top 10.

The one thing that jumps off the page is the performance of the Pacific Northwest. Three teams from Bigfoot Country grace the top seven, with Pac-12 leader Washington at No. 7 and the Civil War rivals Oregon State and Oregon both sitting in the top five heading into their showdown this weekend.

With the Ducks and Beavers facing off along with top-ranked Virginia heading down to No. 6 Florida State, expect even more shake-ups after this weekend.
