Yes their defense is stout but it is not lights out. Their offense is in fact horrendous starting with the very suspect OLine. Not to mention QB carousel which is in fact bad for a football team.
BYU is a better team.
BYU is not good enough to be -3 in turnovers and win. But it also won’t take a KSU game to beat Utah.
It will take a better effort than OSU.
If BYU plays like they did last week they win by 20.
If Utah plays like they have any of the last four weeks BYU wins by 20.
If BYU plays like they did against OSU and Utah plays better than they have in a month, it will be close.
If BYU is > -3 in turnovers, Utah wins.
