But that's the one
An ordinary pass at speed the arms go forward relative to the ground, but it's not a throw forward because they go backwards relative to the player
Why is this so hard that understand?
Rich explains it
That concept is easy to understand, but it's not what the laws or definitions say. The definition says "if the arms of the player passing the ball move forward" and defines forward as "towards the opposition’s dead-ball line."
And, again, "backwards relative to the player" does not work if the player is running towards their own DBL, there it can't be a robust and correct definition!
"Relative to the player" is not a phrase used anywhere in the laws or definitions, no matter how many times you say it.

This is not necessarily correct, because it depends on the direction of travel, the running speed of the player, angle of pass and speed of arm movement... Needless to say, it is ridiculous too think WR expects a referee to accurately process all these parameter at once, or wrote the law/definition with all these factors within consideration.
Maybe we should admit that in reality, and quite reasonably, the law makers did not consider net velocity of the arms (ie considering both forward travel of the player and the movement of the hands simultaneously) and wrote the current definition to be read on face value... Simply, do the arms move forward, towards the opposition's DBL (per the definition of forward), during the pass?
