Troy Williams voluntarily back up to the 1 yardline and was sacked, but the refs spotted Utah at the 5 or 6. Next play they went deep on McChesnee and got a PI to pull them out of the hole. That was the 10 minute drive that ended in a FG. Had the ball been placed correctly at the 1 Utah doesn't dare go deep to pull the PI and BYU gets the ball back, early 4th quarter in great field position.
