ability to beat Michigan (in the most watched game played in the state of Utah EVER)...anyone who thinks Utah gets killed isn't looking at it objectively. They could get killed, but going into the game, predicting that doesn't seem very rational.
1) Utah has a solid team this year with decent depth
2) It's at home
3) Utah won't get beat up in the trenches or with speed on the outside like they would against a Michigan State or an Ohio State type of team
4) Special teams and D usually keeps Utah in the game against lesser P5 schools
5) Kyle has done a relatively good job in openers (granted those are usually against FCS foes)
