I don't think this BYU squad wins in a track meet. We haven't played a ton of teams with the ability to go up and down the field and/or score with quick strikes. Colorado can do that. Our D isn't bad. But Saunders will be the best QB we've faced with the best arsenal of weapons.
I'd like to believe that Jay Hill and his D will have some tricks up their sleeve which can frustrate the Colorado O, and we make them pay for a some big mistakes. In that scenario, maybe the O performs well enough to keep up, and perhaps we pull it out.
But I see it more likely that a Colorado squad with superior scoring ability brings the fire from the outset, and we never seriously threaten them.
