Scrapper,
Just listen to JR on this. He is correct. I know that it is annoying, but he usually is.
He is an assignor and can speak from experience that when the NFHS books instruct you as the official to do something or not to do something, then that is exactly what you should do because if you are ever questioned on your actions by the governing body/league/supervisor/etc. you can point directly to the page in the book and say it says so right here. Basically, it's a CYA thing.
