They passed it only 13 times and made it nearly impossible for Utah to make game-changing plays on defense. Yes the personnel is different and they only scored 17 but the point is that the only way Utah wins this is if BYU turns it over a bunch and allows Utah’s defense to score.
Play the field position game, force Utah to sustain drives and then make the most of opportunities in the ground with the occasional shot down the field. Unless somehow Utah does a total 180 with the bye week they won’t put up more than 14 - 17 on this D regardless of QB.
