Watching the highlights from last year's game is a whirlwind
There's no doubt that BYU was soundly beating Utah in every aspect (but for an oddball interception). The game seems to turn just before the end of the 3rd when Utah converted a 4th&1 on their way to their first offensive TD.
I don't know how things changed so drastically. But I believe this year's squad should be strengthened by last year's heartbreak. And should they find themselves in a similar position this year, I think they hold on and win resoundingly.
