Pretty good document, except for the part that says to bag fumbles by A behind the LOS. Personally, I don't care if that gets a bag or not, but there are supervisors that will downgrade for that.
The thing that does bother me is an official that thinks he needs to throw the bag at the SPOT of the fumble. You need the YARD LINE of the fumble. When you throw the bag at the SPOT, we now have a loose ball, players reaching for it, and a bean bag flying at them. Not only could it be dangerous, it could get in a player's way, and the chance of you reaching the spot through all of those bodies becomes a problem. Get the yard line, away from the pile.
