The Tanner Mangum show continued Saturday with another barely believable, come-from-behind victory for the freshman.

He threw a 35-yard touchdown pass to Mitchell Juergens with 45 seconds left to give BYU its second last-minute victory in as many weeks. The Cougars defeated No.20 Boise State 35-24 as the Mangum magic continued.

"We like to have big explosive plays like that," Mangum said. " … Sometimes it's a little bit improvised on a scramble. Sometimes it's designed. More than anything, I just do my best to make the right decision."

Mangum was far from perfect, completing 17 of 28 passes for 309 yards and throwing two interceptions. But the deep ball worked, and he came through when it mattered most. Jeurgens caught the game-winner in the middle of three defenders after Mangum scrambled out the pocket.

Mangum was making the first start of his career after another shocking victory last week. He introduced himself to the college football world after senior Taysom Hill was lost for the season with a lisfranc sprain in his foot.

Mangum snatched a place in BYU lore with a 42-yard Hail Mary touchdown pass to Mitch Mathews with no time left to beat traditional power Nebraska on the road.
