It is a rivalry game, and things get weird during rivalry games.
New(ish) OC. Not sure what to expect in play calling, and they'll have two weeks to prepare.
Their defense is still good.
Their running back is still one of the best in the conference, and likely second best that BYU will face all year (probably second to Ollie Gordon).
And its in Salt Lake. That will be a tough one. But, not as tough as the UCF game this weekend.
