AIR FORCE ACADEMY, Colo. (AP) — Calvin Tyler Jr. raced 61 yards for the go-ahead touchdown with just under four minutes to play to lift Utah State to a 49-45 win over Air Force in the Mountain West Conference opener Saturday night. The Aggies, who had just one win a year ago, won their third straight game to open the season for the first time since 1978. Tyler carried 19 times for 132 yards and two touchdowns to lead Utah State while Logan Bonner completed 21 of 34 passes for 253 yards and two touchdowns. Andrew Peasley threw three second-half touchdown passes, including a 72-yard bomb to Deven Thompkins with 9:51 to go to pull the Aggies within a touchdown of the Falcons, 45-40. Air Force took a 10-0 lead in the first quarter, but Bonner engineered a 13-play, 71-yard drive capped by Tyler’s first touchdown, then drove the Aggies 92 yards in 11 plays on their next series, giving them a 13-10 lead after hitting Brandon Bowling from six-yards out. Haaziq Daniels connected with Micah Davis on a 56-yard touchdown pass in the second quarter to put Air Force back in front and Dane Kinamon scored just before intermission
