SALT LAKE CITY — All-American wide receiver Robert Woods was face down on the giant red “U” in the middle of the field Thursday night, dazed by a wicked shot.

The scene was indicative of the Trojans as a whole after blunders left No. 13 Southern California down two touchdowns early and Utah smelling upset.

Woods righted himself and so did the rest of the USC offense, with quarterback Matt Barkley showing why he was a favorite to win the Heisman Trophy before the season started.

Barkley led the Trojans to 28 straight points, passing for 303 yards and three touchdowns in a 38-28 victory.

“That was a real low point to give the other team 14 points to start the game, but our team bounced back,” said Barkley, who finished 23 of 30. “We didn’t let that ruin our night.”

Instead the Trojans ruined one of the biggest games in Utah history.

“We wanted to come out fast and we did that,” said Utah wide receiver Kenneth Scott, who caught an 11-yard touchdown pass from Jon Hays and had a 44-yarder nullified by penalty in the second quarter. “Now we just have to finish.”

That the Trojans (4-1, 2-1) showed they know how to do, scoring twice in a span of less than 3 minutes in the fourth quarter to turn a 3-point game into another victory.

Leading 24-21, Barkley tossed an 83-yard TD pass to Marqise Lee to bump USC’s lead to 10 points. Less than 3 minutes later, cornerback Nickell Robey intercepted a pass by Jon Hays and returned it 38 yards for a touchdown.
