Doug Martin ran for 121 yards and four touchdowns as Boise State remained unbeaten and in college football title contention with a 52-21 victory over Utah State Friday. Jeremy Avery added 116 yards rushing and two touchdowns for the Broncos, who gained 243 yards and scored four TDs in the second quarter – two 43 seconds apart to break a 14-14 tie. Boise State added another touchdown barely 2 minutes into the third quarter and what was a close game for about 25 minutes turned into the rout it was expected to be. Utah State fell to 1-51 against ranked teams. Boise State quarterback Kellen Moore was a modest 15 for 29 for 233 yards with a touchdown, breaking a streak of six straight games with three of more touchdown passes. But he had enough help in the backfield to offset his lull. The Broncos rushed for a season-high 323 yards and outgained the Aggies 572-363. Utah quarterback Diondre Borel was 18 for 30 for 201 yards and kept the Aggies alive by avoiding several sacks with his speed, but the Broncos eventually started catching him and Utah State didn't have enough other weapons to keep up after matching Boise State's first two touchdowns. After Robert Turbin tied it at 14-14 on a 24-yard run for the Aggies with 6:28 left in the second, the Broncos drove 73 yards in four plays to retake the lead for good. Titus Young made a diving grab with a defender all over him for a 56-yard catch at the 2, where Martin easily ran it in for a 21-14 lead. Then Utah State fumbled a handoff and Ryan Winterswyk recovered at the 9 for the Broncos and Avery scored on first down, putting the Broncos up 28-14 with 4:04 left in the quarter. Being down two touchdowns at halftime would have been tolerable for the Aggies, but another defensive lapse late in the period allowed the Broncos to drive for a 1-yard touchdown by Martin with five seconds left in the half. The Aggies almost had Boise State stopped on third-and-10 with about a minute left, but Martin broke through for a 17-yard run to keep the drive going. The Broncos opened the third quarter with a 71-yard drive, needing only four plays to score again on a 32
