LOGAN, Utah — Kellen Moore didn't need to throw his usual three touchdown passes.

All the Boise State quarterback had to do was hand it off and watch Doug Martin and Jeremy Avery go.

Martin ran for four touchdowns, Avery ran for two more and both topped 100 yards rushing to help the sixth-ranked Broncos remained unbeaten and in BCS contention with a 52-21 win over Utah State last night.

"It makes life a little easier," said Moore, who passed for a modest 233 yards and one touchdown.

Moore had thrown for at least three TDs in six straight games, but the streak ended last night as the Broncos (11-0, 6-0 Western Athletic Conference) rushed for a season-high 323 yards.

Boise State broke a 14-all tie with four touchdowns in the second quarter, two just 43 seconds apart to break down the Aggies (3-8, 2-5).

"We just came out with an intensity and didn't back down. We just kept pounding and pounding and pounding," said Martin, who had 13 carries for 121 yards. "It's nice. I've just got to give out props to my O-linemen."

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.

The Broncos try to keep the streak alive next week at home against Nevada, which has won seven straight.

Utah State fell to 1-51 against ranked teams, getting outgained 572 yards to 363 in the latest loss.

"They are very good and they did exactly what they have done in every game all year long," Utah State coach Gary Andersen said. "I though they controlled the line of scrimmage on both sides of the football. When that happens, it puts you in a position where you have to take a lot of chances."

After Robert Turbin tied it at 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.

Another defensive lapse later in the period allowed the Broncos to drive for a 1-yard touchdown run by Martin with 5 seconds left in the half.
