Quote ="Code13"So are you genuinly saying Carvell did not extend his arm and promote the ball forward?
Are you actually saying that?'"
Was your question so good that you thought you'd ask it twice? Or do you think that being condescending helps you to discuss the point?
What I am saying is pretty simple: that he had not been stopped short of the line.
If he had been stopped short of the line, and then extended his arm to take the ball over the line then that would have been a double movement. But as he wasn't, it wasn't.
Quote ="Code13"So if he had passed the ball, would he have been allowed to play on?'"
I would say not. The ball-carrying arm had contacted the ground, and so the tackle would be complete at the point where his forward motion stopped. He couldn't "untackle" himself.
Quote ="Code13"Or if he had got up would he have been allowed to carry on? '"
I would say not, for the same reason.
Quote ="Code13"He was down, he was in contact with a defender and he had to project his arm to score and its that last part thats the key in all this.'"
No, the fact that his forward motion had not been stopped is the key. You keep overlooking it.
