Disclaimer - I have no clue what will happen on Saturday. Not predicting any outcome.
While losing this game would be disappointing, though not catastrophic, the opposite could be galvanizing. If BYU were to come out and have a KSU-like game, they could shut up all the naysayers and people who still think that BYU is a fraud. I'm not exactly sure why, but I feel like there's more eyes on BYU this week. This could be a great opportunity to curb stop the opponent and position themselves for a more favorable view in the eyes of the media.
