On field crew communication

[Rick KY]

I am not sure that any communications would work very well at the time the play is happening. There are too many sounds and sights to make signals or words effective while the play is live. I do think that covering these things that go wrong in your pre-game is necessary. Perhaps someone can devise a signal such as the one used to signal a tipped kick or pass to alert officials. Although, if no player attempts to recover the loose ball the whistle is not really inadvertant. In that case you simply kill the play and enforce the foul as B chooses.
