Illegal Forward Pass?

[BktBallRef]

This question was posted on another forum where I'm the moderator. The forum is a HS football forum in a state where NFHS rules are used.

"Can a QB run past the LOS and then go back behind the LOS and legally throw a pass?"

My reply was "Yes, he certainly can."

A second poster questioned my reply. I explained that the play is not addressed as illegal in the NFHS rule book and is legal. His reply?

"That has to be the WORST interpretation of that rule I have ever seen/read.

To the original poster...

I wouldn't even consider for one minute to send your QB beyond the LOS then back up to throw a pass. I can guarantee that 99.9% of refs are going to throw the laundry out every time. Again, this is a HORRIBLE interpretation of this rule."

Would any of you be interested in helping this gentleman better udnerstand the rule? He just doesn't believe me.
