It's rivalry week in Provo as BYU and Utah face off for the last time until 2016. Chuckie Keeton and Utah State have a second chance to beat a Pac-12 team on the road against USC on Saturday. Stanford and Arizona State face off for national recognition and credibility.

Just another great week of college football as many of week four's best games happen in the West.

So, what games do you need to watch this week?
