07:15 AM ET 06.20 | Officially, summer begins this week, which means preseason camps are now in sight. [Let's] take a look at some power rankings. ... 1. Oregon: Mark Helfrich is ready to lead the program, and Nick Aliotti remains one of the more underrated defensive coordinators in the nation. Stanford could have easily had this slot because of the win over the Ducks last year. But Heisman Trophy contender Marcus Mariota could have an even more prolific season than 2012, so I gave the initial nod to the Ducks -- by a hair. 2. Stanford: Head coach David Shaw has this program trending toward BCS national championship game territory. The defense remains stout and could be even better than last year, and quarterback Kevin Hogan is legit. The run game should also be fine without Stepfan Taylor.
