BOISE, Idaho (AP) -- After an anemic offensive showing in its season opener, Boise State proved Saturday its offense is plenty potent as the Broncos exploded for 676 yards in a 37-24 victory over Colorado State in the Mountain West Conference opener for both teams.
Boise State running back Jay Ajayi provided most of the spark for the Broncos, finishing with 219 yards rushing, 61 yards receiving and three touchdowns. The team's 676 yards was the fifth most in school history.
"It's been great getting a lot of opportunities to touch the ball and make big plays for the team," Ajayi said. "It's been really fun seeing how my role has developed from last year to this year with the different style that we're doing."
It's a style that worked against Colorado State in every facet of the Broncos offense.
Grant Hedrick was 22-of-33 passing for 352 yards with two touchdowns and an interception. He also ran for 80 yards and a touchdown.
"Things went our way and the fact that we were able to do it at home on The Blue with that type of fan base was exciting," said Boise State coach Bryan Harson, who notched his first win with the Broncos and avoided the school's first 0-2 start since 2005. "It was a good start for us in our conference as well."
Colorado State (1-1), which saw Dee Hart and Treyous Jarrells each gain over 100 yards in its season-opening win over in-state rivals Colorado, gained 28 yards rushing on 23 carries.
Instead, the Rams were forced to rely on Garrett Grayson, who was 31-of-58 passing for 434 yards with three touchdowns and two interceptions. Joe Hansley led the team in receiving with seven catches for 149 yards and a touchdown, while Rashard Higgins had 11 receptions for 143 yards.
Colorado State, which has dropped all four meetings with Boise State since the Broncos joined the Mountain West Conference in 2011, moved the ball effectively in the game's opening possession before stalling at the Boise State 20 and settling for a 39-yard field goal by Jared Roberts.
That was the only lead the Rams would hold.
Hedrick responded with his first opening touchdown drive in his career, leading Boise State 75 yards in nine plays, which ended on an 8-yard touchdown run by Ajayi. Colorado State blocked the extra point, leaving the Broncos with a 6-3 lead.
On the Broncos' next possession, Hedrick rushed for 30 yards on three carries in moving Boise State 70 yards on 12 plays. His 1-yard sneak capped the drive and gave the Broncos a 13-3 lead. Colorado State would never get any closer than that.
Trailing 37-10 in the fourth quarter, Colorado State attempted to get back in the game with a pair of late touchdowns and a goal line stand. Boise State sealed the victory, however, when Jeremy Ioane intercepted an errant Grayson pass with 1:28 remaining.
Matt Miller caught eight passes for 151 yards and a touchdown and overtook Austin Pettis for the most career receptions at Boise State.
