USC pounces on first Stanford mistake

LOS ANGELES -- Not to repeat myself but mistakes will kill you.

Stanford's first of the game -- a Toby Gerhart fumble forced by USC linebacker Chris Galippo -- set up 36-yard TD pass from Matt Barkley to Brice Butler and now the score is 21-14.

USC is within range.

The Cardinal's nose has now been bloodied. Will they respond?

The screws are tightening.
