BOISE, Idaho (AP) - Jon Helmandollar rushed for a school-record five touchdowns, and No. 13 Boise State clinched at least a share of its third straight Western Athletic Conference title with a 55-14 win over Louisiana Tech Saturday.<br>
<br>
Boise State (10-0, 7-0) extended the nation's longest win streak to 21 games and tied BYU's record for the most consecutive conference wins at 25. The Broncos last WAC loss was Nov. 3, 2001, a 48-42 setback at Louisiana Tech.<br>
<br>
The Broncos can claim the WAC title outright beating Nevada next week. They are the first WAC team to start 10-0 since Wyoming in 1996.<br>
<br>
Louisiana Tech (5-6 overall, 4-3) lost for the fifth time this season to a team ranked in the top 25. The Bulldogs previously fell to Miami, Auburn, Tennessee and Texas-El Paso, and are now 2-26 all-time against ranked opponents. <br>
<br>
Louisiana Tech needed wins in its final two games to become bowl eligible.<br>
<br>
Jared Zabransky threw for 317 yards and a touchdown for Boise State, who racked up 629 total yards and scored 38 second half points.<br>
<br>
Last year, Ryan Dinwiddie threw for 569 yards and Boise State had 732 yards of offense in a 43-37 win over the Bulldogs.<br>
<br>
Louisiana Tech running back Ryan Moats - No. 2 in the country, averaging 164.2 yards - was held to 60 yards on 19 carries and was mostly ineffective in the second half as the Bulldogs were forced to throw the ball.<br>
<br>
Helmandollar scored twice in the first half from the 1, twice in the third quarter on runs of 4 and 12 yards and again in the fourth from 3 yards out. He has 10 touchdowns in Boise State's last three games and his 91 yards was a career-high.<br>
<br>
Ahead 17-14 at halftime, the Broncos pulled away in the second half, scoring 28 points in a 5:23 span of the third and fourth quarters.<br>
<br>
Helmandollar scored from 4 yards with 2:16 left in the third, and his fourth TD from the 12 put the Broncos ahead 34-14 with 32 seconds left in the quarter.<br>
<br>
Louisiana Tech's Erick Franklin fumbled the ensuing kickoff, recovered by kicker Tyler Jones. Three plays later, Lee Marks scored on a 19-yard run to put the Broncos up 41-14 just 13 seconds into the fourth.<br>
<br>
On the next drive, Zabransky hit Jeff Carpenter on a screen pass and Carpenter ran 31 yards for the TD. It was Boise State's first passing touchdown since the fourth quarter against Fresno State on Oct. 23.<br>
<br>
Boise State had scored 21 straight offensive touchdowns rushing.<br>
<br>
Louisiana Tech led only once in the game. Trailing 10-7 in the second quarter, the Bulldogs silenced Bronco Stadium as Matt Kubik found Moats on an 18-yard TD pass to make it 14-10. It came following a Boise State fumble at its own 25.<br>
<br>
Jones kicked field goals of 39 and 33 yards for the Broncos.
