has shown they're very vulnerable to giving up big runs up the gut. It's how Houston beat them. It's how ASU beat them. Even TCU. They're also vulnerable to a methodical passing attack. I don't know if they've been tested by a team like BYU is starting to show yet.
On the flip side, their O-line has been a disappointment for them this year. That's been another factor in their bad offense. They've haven't been able to buy their QB time, giving up lots of pressure and sacks. That's another thing BYU should be able to exploit well.
That all said, Utah also presents BYU with the toughest defense they have faced yet. That's why I think Utah will hold BYU to about 31, a bit under BYU's average score. I also think Utah forces a turnover or two, perhaps giving Utah a short field to score some points with.
But on the flip side, I think BYU also forces a couple turnovers, and maybe more.
The biggest matchup though will be Utah's red zone defense, which has been elite, vs BYU's "blue zone" offense, which has also been very efficient and productive.
Utah certainly has the better D-line. Seems like BYU is better & deeper in all other position groups though, from linebackers to the receivers, from QB to kicker, from O-line to secondary.
