Some shakeup from the preseason power rankings as we end week one of college football. We learned that the Pac-12 North is absolutely terrible, and the Arizona schools definitely showed their weaknesses this weekend. Here's the power rankings from last week if you wish to look back and compare.

The Trojans ran like a well-oiled machine this weekend and played exactly how you would expect them to vs. Arkansas State. A consistent run game and a lot of options at receiver give their offense balance. Their defense has quite a few freshmen playing and they performed well, including corner Iman Marshall.
