Utah is a good team this year. Not great, but good. Their only screw up was letting Washington State overtake them for a 1-point loss. Their other 3 losses were to very strong teams: Oregon, Arizona and Arizona State, all in the Top 15.
Colorado is a bad team. They lost to Colorado State and are 0-8 in the PAC-12. Their only wins are UMass, a team getting kicked out of the MAC, and at home against Hawaii (they might have lost in Hawaii). If Utah loses that game, they don't deserve a bowl game.
