The fact that Utah had Wilson chucking it 5 out of the first 7 plays (Granted on one play Wilson turned the wrong way for the hand off and got lit up) shows the game plan Utah had. They wanted Wilson to have his day.
Heck, Utah's best player, Micah Bernard didn't touch the ball once after the 13:34 mark in the 4th.
I get the situation, but Utah still had the ball 3 more times. Not once did they give it to him after Arizona went up 23-10, they had a 3 and out. There was still a lot of game left (8 minutes) at that time.
