It was judgement day in the Pac-12 on Saturday, with five of the conference's six teams squaring off in league games that would end up having a major impact on this week's Bleacher Report Top 25. And they did, though the results were quite surprising.
And they weren't the only shocking outcomes from Week 4, and thus we've again got a lot of movement in our rankings.
Nineteen of our college football staff voted on Bleacher Report's Top 25: writers Ben Axelrod, Greg Couch, Justin Ferguson, Bryan Fischer, David Kenyon, Ben Kercheval, Adam Kramer, Brian Leigh, Mike Monaco, Brian Pedersen, David Regimbal, Barrett Sallee, Brad Shepard, Greg Wallace and Christopher Walsh; video experts Michael Felder and Sean McManus; and editors Eric Bowman and Hunter Mandel.
