Clayton Powell sealed Idaho Falls' 40-35 non-conference victory over Blackfoot when he intercepted Taylor Pearson's pass with 10 seconds remaining on Friday night.
Down 40-14 entering the fourth quarter, the Broncos finally got their offense untracked and scored three times to make things interesting.
With the Tigers (1-0) trying to play conservatively to protect their big lead, the Broncos (0-1) got an 11-yard touchdown run from Austin Capson, a 10-yard run from Kylar Haddon and an 11-yard pass from Pearson to Matt Peterson and three points-after-touchdowns from Gabe Botello.
That drew them within five points with 1:50 remaining in the game. Botello's onside-kick attempt failed, but the Bronco defense stopped the Tigers on fourth down to get one last chance with 25 seconds to go.
Blackfoot got past midfield with 13 seconds left, but Powell spoiled the Broncos' comeback bid when he picked Pearson off about the Tiger 10-yard-line.
"Our execution is going to get better with experience," said Broncos' coach Stan Buck as he reviewed his team's early woes. Idaho Falls had 306 yards of total offense in the first half en route to a 34-14 edge. The Tigers pushed their advantage to 40-14 before Blackfoot got things working.
"How many mistakes did Idaho Falls make?" Buck asked. "Not many. How many did we make? Tons."
Buck noted that Pearson, a sophomore who was too big to play quarterback in Grid Kid competiton, will get better as the season progresses.
Jake Thornberry led the Tigers with three touchdowns on runs of 1, 3 and 18 yards. Powell had a 15-yard TD catch from AJ Martin while Bryaden Andrus and Terrell Payne each had short scoring runs.
Haddon finished with two scores and 150 yards rushing.
Blackfoot will be at Skyline next Friday.
