It won’t be difficult for BYU fans to remember the 21st night of September. The Cougars captured a hysterical upset victory Saturday against No. 13 Kansas State, and while the game action was thrilling, many of the contest’s most memorable highlights actually came off the field.

Here are the highlights from BYU's convincing win over Kansas State. The BYU defense was the story of the night. Not only did the Cougars keep the Wildcats out of the endzone (for the second consecutive game against a P4 opponent),

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.
