What if the rule changed to make this much easier to officiate? Suppose 2-19-2-b read as follows:
"When a Team A player is holding the ball to pass it forward toward the neutral zone, any intentional forward movement of his hand or arm starts a forward pass. If a Team B player contacts the passer player or ball after forward movement begins and the ball leaves the passer’s player's hand, a forward or backward pass is ruled regardless of depending on where the ball strikes the ground or a player."
Would this change the game for the worse? I doubt it. Instead I think it would change the game for the better. It would simply remove an occasional lucky break that the offense currently gets - a lucky break that basically depends on which way the R rules on a 50/50 call. Changing the criterion, so it's only a forward pass if the ball goes forward, isn't just visibly clearer, it's also arguably more fair. If Team A loses the ball, having failed to throw it in a forward direction, why shouldn't it be a free ball?
