NORMAN, Okla. -- Since Sam Bradford took over as quarterback, winning sure seems simple for No. 3 Oklahoma.
Bradford threw for 255 yards and three touchdowns in another efficient performance, and the Sooners notched their third blowout of the season with a 54-3 win against Utah State on Saturday.
"Nothing's easy at all, but I got in that rhythm early and I did feel I got a lot of confidence that way and saw things very clearly," said Bradford, a redshirt freshman who entered the game as the nation's top-rated passer. "I felt really comfortable today."
Bradford completed his first 11 passes -- including two for scores -- to reach 21 straight passes without an incompletion. He'd already had a school-record run of 22 straight completions that ended in the Sooners' 51-13 rout of Miami last week.
Malcolm Kelly caught his sixth and seventh touchdown passes of the season and Allen Patrick showed his sprained ankle has fully healed with a 69-yard TD sprint as the Sooners (3-0) piled it on again.
Oklahoma has won its first three games by 158 points -- the most dominant start to a season since 1972, when the Sooners outscored their first three opponents 169-6.
"If we get 12 of these wins right here, then that would be just fine with me," Bradford said. "You really can't complain with this stuff."
Kevin Robinson had eight catches but gained only 38 yards for Utah State (0-3), which has been outscored 230-27 in four meetings against Sooners teams that were all ranked in the top 10.
After suspending leading tackler Antonio Taylor earlier in the week, the Aggies lost second-leading tackler Jake Hutton when doctors couldn't get his heart rate to settle down. Leading rusher Curtis Marsh left in the fourth quarter with an ankle injury.
"Obviously we didn't give them any type of game that we wanted to try to play out there," Utah State coach Brent Guy said.
Kelly, who entered the game tied for the NCAA lead with five touchdown catches, scored on throws of 27 and 17 yards from Bradford as Oklahoma built a 38-3 halftime lead. Coach Bob Stoops started pulling his starters midway through the third quarter after DeMarco Murray's 92-yard touchdown run -- the third longest in school history -- made it 45-3.
Stoops credited his team for having a "methodical" approach to games that prevents a let down.
"We don't want to hit that plateau, and that's what kind of gets good teams to just kind of be average or just be good, not great," center Jon Cooper said. "We just keep striving to get better every day in practice and every week."
The Sooners opened up their bag of tricks on their first possession, with Juaquin Iglesias taking a double reverse 35 yards down the left sideline for a quick 7-0 lead. Bradford faked a handoff to Patrick and gave the ball to Kelly, who flipped it to Iglesias as he curled around from the right flank.
Oklahoma also scored on its next two possessions, with Bradford's 8-yard pass to tight end Joe Jon Finley giving the Sooners a 21-0 lead.
Bradford completed 19 of 26 passes. In his first three starts, he is 59-for-74 for 823 yards and 11 touchdowns.
Bradford's first incompletion came when he overshot Kelly on a post pattern deep downfield, and his first career interception came on the next play. He was hit as he threw, and the ball sailed high and tipped off Iglesias' hand before Roy Hurst dove to intercept it.
The Aggies converted it into a 30-yard field goal by Peter Caldwell for their only score, but Patrick responded on the very next play from scrimmage and showed no ill effects from the ankle injury that kept him out of the second half of fall practice.
"Now I feel like I'm back," said Patrick, who was held out of Oklahoma's opener and had only seven carries against Miami. "I'm my normal self."
Patrick finished with 113 yards on nine carries as Oklahoma racked up 343 yards rushing and outgained Utah State 617-153.
Guy said Patrick's run was a "back breaker" after the Aggies got their first sniff of momentum.
"I didn't feel like we did the things we came in here and set as goals to do. We just needed to execute, not do silly things," said Guy, who was particularly disappointed in the Aggies turning the ball over and letting the Sooners convert long third downs.
"More than the actual end and the score, those are the things I'm more disappointed in. Those are the situations we have to win to win games in the WAC."
