It is thrown from in or beyond the neutral zone after a ball carrier's entire body and the ball have been beyond the neutral zone.
-------------------------------------------------------------
A lot of unnecessary words in that statement. "from in or behind the neutral zone" is superfluous. The rest of the sentence is all that is needed, because, once the ball is in possession (by anybody) beyond the NZ, then a forward pass may not be made, by anybody, anywhere, anytime, thereafter.
And, "ball carrier's" should be replaced with "passer." By definition, the person who makes a forward pass is the passer, regardless if the pass is legal or illegal.
"It is thrown after a passer's entire body and the ball have been beyond the neutral zone."
But, even that leaves a gap in the rule. By strict reading, the passer may have been beyond the neutral zone, and the ball may have been beyond the neutral zone, but the passer may not have been in possession of the ball beyond the neutral zone. "How?", you ask? The ball is loose from a fumble, and the Team A player who eventually throws the pass is beyond the neutral zone, then the ball gets muffed back behind the neutral zone, where that same Team A player moves back being the neutral and recovers the ball, then throws this forward pass in question. Technically, the ball was not in possession beyond the NZ, so this pass would be legal. And that may be what is intended. But the rule could be better written to be 100% clear:
"It is thrown after the ball has been in player possession beyond the neutral zone."
I they don't want a forward pass to be legal if the loose ball has been beyond the neutral zone, period (in player possession or loose), then travels back behind the neutral zone, then the rule should read:
"It is thrown after the ball has been beyond the neutral zone (loose or in player possession)."
