Utah would not have started 5-0. That stretch is too much.
There's a reason Utah has scheduled easy wins the week before and the week after the BYU game. If you look back a few years, Utah lost games they shouldn't have lost because the BYU game was too much emotionally and physically. Utah's schedule this year is perfectly suited to exert all energy in their few difficult games. And even then they lost to ab average USC team. No question the BYU schedule is much more of a grind than Utah's. Question is would Utah be at one loss or two. Chances are they're at two.
