BOISE, Idaho (Ticker) -- Jon Helmandollar had a season's worth of touchdowns in just one afternoon for No. 12 Boise State.
Helmandollar scored a school-record five touchdowns as the Broncos won their 21st straight game with a 55-14 victory over Louisiana Tech to clinch at least a tie of the Western Athletic Conference title.
Boise State (10-0, 7-0 WAC), who collected 629 yards of offense, scored the final 45 points after trailing, 14-10, midway through the second quarter.
"We ran some plays that we needed to make and the guys came up and made those plays," Boise State coach Dan Hawkins said. "I am pleased with the overall effort. We just need to continue to do that for the rest of the season."
Helmandollar, who scored on half of his carries, rushed for 91 yards after coming into the game with six TDs and just 119 rushing yards.
In the Broncos' past three games, 21 of their 23 touchdowns have been on the ground.
Jared Zabransky completed 20-of-30 passes for 317 yards, including a 31-yard touchdown to Jeff Carpenter in the fourth quarter.
The Broncos, who own the nation's longest overall and home (25) winning streaks, have won 39 of 40 on the blue turf here and tied BYU's record with 25 consecutive conference victories. They close the regular season at Nevada next Saturday.
"There's one more game and hopefully two more," Hawkins said. "We know the importance of that. When the dust settles, we'll sit back and say, 'Hey, nice season.'"
Ryan Moats, the nation's second-leading rusher, was held to 60 yards on the ground. He also scored on a 20-yard TD pass from Matt Kubik that gave Louisiana Tech (5-6, 4-2) a brief lead.
