Many head coaches have a police escort off the field after the game. There are plenty of good reasons for this and we see virtually no downside to this when travelling.
After BYU's loss Saturday night to Utah (which came down to the last second, a couple of times), Bronco Mendenhall was leaving the field (along with his escorts) when some Utah fan starts verbally taunting him and approaches him. In the video below you'll see Mendenhall actually took a few steps towards the ____ before properly deciding to continue on into the locker room.
Quick note to all coaches and game day operations folks...instruct your police escorts that if any fans of the other team approach you and the coach that it is their job as escorts to immediately defuse the situation. Don't allow the coach to get caught up in something this stupid.
