BOISE — Boise State’s first play of the scrimmage Saturday was a handoff to the Heisman Trophy contender — soon-to-be Heisman favorite? – Ashton Jeanty. You guessed it: the Aggies couldn’t tackle him and 63 yards later he was in the end zone.

That big play foretold the kind of Saturday night it would be for the Broncos offense in their home game at Albertsons Stadium.

Jeanty primarily played with Utah State’s overwhelmed defense, and his dynamic ability to draw attention opened up the field for the rest of the offense. The Broncos (4-1, 1-0 Mountain West) led 49-17 at the half after amassing 439 total yards, allowing Jeanty to take the seat for the second half, and finished with a 62-30 victory .

The offense finished the night with spectacular numbers: 599 total yards, including 303 passing and 296 rushing; 27 first downs; an average of 8 yards per play; nine scoring drives with only two punts; and TD drives that covered 75, 75, 85 and 86 yards.

In addition to his first carry, Jeanty was responsible for another one-play scoring drive after the Aggies got a long touchdown pass to make it 14-10. He took a handoff from QB Maddux Madsen, shrugged off defensive end Gabe Peterson’s half-hearted tackle attempt and raced 75 yards for his second TD to make it 21-10 with 14:12 to go in the second quarter.

That was Boise State’s sixth one-play scoring drive of the season, which leads all of college football. Jeanty rushed for 186 yards and three touchdowns on just 13 carries in the half. Then he was done for the night. And when the junior superstar didn’t deliver highlights — he now has 1,031 yards on the season and 16 touchdowns — other Broncos stepped up.

Madsen completed 21 of 25 passes for 266 yards, including three short touchdown throws in the first half. He connected with tight end Matt Lauter and receiver Prince Strachan on big completions of 22 yards, and hit Chase Pendry with a 42-yard strike that set up Jeanty’s third score, this one from 6 yards out, ending the fifth TD drive from the Broncos.

Madsen took the spot in the third quarter with Boise State comfortably in front, and freshman Malachi Nelson took the snaps afterward. Backup running back Jambres “Breezy” Dubar had a 22-yard run and also caught a pass that set up a first-and-goal while pinning Jeanty in the first half.

Dubar was one of nine different Broncos with a reception, while Madsen and Nelson spread the ball effectively. Dubar finished with 65 yards rushing and a touchdown in the second half, wide receiver Cam Camper caught five passes for 59 yards and a TD, and Austin Bolt had a pair of receiving scores, from 3 and 4 yards out.

Boise State also got a huge play from its special teams, with running back Dylan Riley taking a kickoff back 96 yards for a touchdown in the second quarter. Bolt also had a long kickoff return in the second half that set up a score.

The Broncos were a bit inconsistent defensively and also fell victim to big plays, with Utah State senior receiver Jalen Royals doing his best to match Jeanty’s explosiveness. Royals had eight catches for 200 yards in the first half, with touchdown receptions of 59 and 75 yards, and finished with nine catches for 211 yards.

The Aggies’ senior quarterback, 6-foot-4 Spencer Petras, completed 27 of 41 passes for 372 yards and three touchdowns, and Utah State totaled 507 yards. But it wasn’t nearly enough.

The Aggies (1-4, 0-1) trailed 55-17 before a pair of late touchdowns made the score a little more respectable.

The Broncos, likely to rise slightly from their No. 21 ranking in the AP Top 25 poll, once again played without starting linemen Mason Randolph and Roger Carreon. Head coach Spencer Danielson even confirmed this week that Randolph, the team’s center, is out for the season.

Freshman running back Sire Gaines, junior receiver Chris Marshall, redshirt freshman tight end Matt Wagner and sixth-year cornerback Markel Reed were also out. Redshirt senior wide receiver Latrell Caples, who missed last week’s win over Washington State, was listed as a game-time decision, and he did make a few plays, catching one pass for 14 yards in the half.

The three-game homestand now over, Boise State is back on the road – well, back in the air – to play Hawaii next week. Kickoff is Saturday at 9 p.m., mountain time.

The Broncos’ next home game isn’t until next month when they host San Diego State on Friday, November 1 at 6 p.m. This is the result of the fact that their second bye week this season is sandwiched by a few away games.
