Unless you are specifically challenging someone who says Utah is going to blow you out.

I think there’s a 15% chance Utah blows you out by more than 15
30% chance it’s a 5-14 point game for Utah
30% chance Utah wins by 4 or less
25% chance BYU wins

That’s my prediction. BTW, that prediction slightly favors BYU in terms of covering the spread so that wouldn’t be a great bet.
