Quote: hula89 "They dont play only that type of forward rule though thats the problem. Its also (unofficially) based basically on being behind the passer when you receive it assuming he is still moving forward (aka the momeuntum rule) this is why Charnley's try seemed forward because whoever passed it out to him is tackled after he has passed it (penalty btw for all those moaning about wheeler!) and so doesn't continue to move forward however the ball does and so does charnley.
If they only played to the rule you state for checking then I can guarantee that about 90% of tries sent to VR would need to be chalked off.'"
Exactly. It is the angle that the balls travels relative to the players (who are running forward), not relative to the pitch, that governs whether it is a forward pass or not.
That doesn't preclude the point BackrowSaint was making though. On a VR you can still draw a line from the passer to where the catcher was when the pass was started, and if the angle is forward, it's a forward pass. It wouldn't take any longer to do than making a decision about players being offside at a kick for example.
