Three-point stance: Inside look at USC

Posted by ESPN.com's Ivan Maisel

1. Aaron Corp is out for up to two weeks with a knee injury, which will hamper his ability to bootleg, something no USC quarterback has had under Pete Carroll. Freshman Matt Barkley, as impressive as he looked in the spring, made a couple of huge unforced errors facing live bullets in the spring game. If Barkley must play the opener, how tight will his leash be? And for heaven's sake, whatever happened to Mitch Mustain?

2. In the new book "Always Compete," Steve Bisheff gets both Carroll and UCLA offensive coordinator Norm Chow to confirm that Chow left USC in 2005 because Carroll took away Chow's play-calling duties to keep Lane Kiffin and newly rehired Steve Sarkisian happy. "Because of job opportunities some of our young guys had elsewhere, we had to do something to keep them," Carroll said. USC hasn't finished No. 1 since Chow left.

3. Bisheff also writes that Carroll knew there might be a problem at Oregon State last season when he stood up on the pregame bus ride and saw his team asleep. The Beavers raced to a 21-0 lead and upset No. 1 USC, 27-21. After the Trojans followed with a 44-10 rout of Oregon, Carroll couldn't stifle his anger at himself for the poor job he had done in the previous game. Bisheff takes advantage of special access to Carroll and the Trojans to explain what makes the game's best coach tick.
