LOS ANGELES -- After a sloppy first quarter, USC exploded for 28 points in the second quarter, ending just about all the mystery in this one.
Turning point: San Jose State went up 3-0 late in the first quarter. The Trojans then scored on their next four possessions, while their defense took over the line of scrimmage.
Stat of the half : USC had two first downs and 77 yards in the first quarter. They had nine first downs and 207 yards in the second quarter.
Best player in the half: When USC quarterback Matt Barkley found receiver Damian Williams, good things happened. Williams caught two passes for 50 yards -- the second a 33 yarder that was mostly him slicing through the San Jose State secondary -- on the Trojans second touchdown drive. That seemed to be the moment when the Trojans asserted themselves. Williams finished with three receptions for 67 yards and should be the first guy Barkley looks for.
