If you're the head of umpiring at the AFL, and you have a small pool of talent to draw from, and sections of the public are baying for one of the umpire's blood, do you throw that umpire out to be sacrificed to appease the masses, or protect him or her for a week or so until the heat comes off, have a quiet word about what they did wrong and give them time in the seconds to work on it?
We would expect an AFL coach to protect their players, for the benefit of that player and to send a signal to the others in the squad. Why should an umpires coach be any different?
