Halftime: USC 42, California 0

Wow. That looked like old school USC. You know: 2002-2008. Not 2009-2010.

And California looked like it did during the Tom Holmoe era.

The Trojans are just whipping Cal, 42-0 at the half. Absolute dominance on both sides of the ball, and it's more about how well the Trojans are playing than how poorly Cal is.

Though, to be clear, the Bears look terrible.

If this sticks there is a HUGE sidebar: USC is off until Oregon visits on Oct. 30. Though you might think the Trojans would want to suit up again as soon as possible after this one, it also means they should have a renewed verve as they use the extra week to get ready for the Ducks spread-option.

And that game suddenly feels like it will be competitive instead of a Ducks coronation.

USC has 372 yards and 20 first downs. Cal has 65 yards and three first downs.

And I picked Cal to win. Yeesh.

Matt Barkley has completed 20 of 29 for 257 yards with five touchdowns and no interceptions. He's now got 20 TD passes this year.

Cal's Kevin Riley? He's 3 of 12 for 51 yards with two interceptions.

Will he start the second half, or will coach Jeff Tedford give backup Beau Sweeney a shot? Maybe he should, and I never anticipated typing that at the beginning of the season.

It can't get any worse for Cal. Or any better for USC.
