that would have the best chance to beat them, which IMO starts with the O line. Utah prides itself on its D line's (as well as D as a whole) but it starts on the D line and then the corners so they can play man and bring extra pressure on the QB. IMO you combat that by building a fantastic O line and being able to run the ball and protect the QB when he needs to pass. Strong TE play also makes it hard on the D Utah runs because they then have to focus on stopping the TE which limits their ability to bring extra pressure.

BYU's O line and ability to run and pass to the TE last year I think was key in finally beating them. The coaches also need to get the players to match Utah's intensity. Utah forces teams to be ready to fight and to do it the whole game. When opposing teams are not ready or prepared to do that, Utah ends up gaining the momentum. (Thats another thing Utah is very good at. fighting to keep momentum on their side) You see them really step up and try and pull out everything they have to regain momentum when they lose it or to respond when the other team scores.
