Tanner Mangum's brother makes incredible TD catch for Idaho State

BYU's Tanner Mangum made a throw that will wind up on the 2015 highlight reel. On the same day, the quarterback's brother made a pretty great grab, himself, in Idaho State's season opener, too.

Tanner Mangum's throw to Mitch Mathews gave the Cougars a 33-28 victory over Nebraska in Lincoln on Saturday.

On the same day, the stakes were lower as Idaho State opened against Black Hills State. The game was a rout, with the Bengals rolling 55-0 over their RMAC opponent.

Madison Mangum is a redshirt senior receiver for Idaho State. He grabbed five pass for 78 yards and three touchdowns.
