With the status of Bo Nix uncertain, it's hard to put faith in the Oregon offense with Thompson under center. Oregon will likely lean more on their run game here but there is a reason why UTAH is favored over the Ducks.
Coaching and a better defense!
These teams played twice last year and Utah won them both in convincing fashion. Oregon is coming off a tough loss at home to Washington in what almost certainly eliminated them from any playoff hopes and probably not gonna be hugely motivated in this one.
