I think Utah goes 7-5, with losses to BYU, USC, UCLA, Washington, and Oregon.
I think BYU goes 10-3, with losses to LSU, Wisconsin, and Mississippi State.
I think the Utah/BYU game is 50/50, but I'm leaning BYU since it's at home so that's my pick. Whether we win that game or not this year is the success of the season or not, as 10-3 with that win is a successful season.
