BYU upset No. 13 Kansas State 38-9 late Saturday night by blowing up the Wildcats in the middle of the game. The Cougars stunned the Big 12 co-favorite with a barrage of huge plays that created a freight train of momentum K-State could not answer.

K-State (3-1, 0-1 Big 12) suffered its first loss of the season and watched in disbelief as BYU (4-0, 1-0 Big 12) ran away with things for a lopsided win that was played late at night in the mountains of Utah.

The return gave BYU a four-score lead and sent LaVell Edwards Stadium into collective chaos. The Cougars went on to rout No. 13 Kansas State 38-9 in their Big 12 opener. The Cougars got there thanks to a most unlikely sequence of events.
