If you want to boost your perception in the minds of the voters, you gotta blow out supposedly inferior teams aka cover the spread, or at least come close.
Not that I have any delusions about making the CFP, but a NY6 bowl berth is very much in play IF BYU can play a complete game on both sides of the ball. Fortunately we haven’t needed to do so to get to 4-0, but if we want to get to 12-0 or at least 11-1, we’ll need to improve.
