Err - no.
Law 14.1 says he can't make a tackle. It says he has to release the ball to the player on their feet. It says the Player on their feet has more rights to teh ball than the player on the ground. BUT it also says that if the player on the ground may immediately play the ball etc.
As for the possession bit (and I got accussed of the "legal arguement"
). Ball rolls towards player on ground, they pick it up and then pass/place etc. Are you saying they never have posession? No different to a player going to ground to claim a ball.
Perhaps I can phrase my arguement slightly differently.
Law 14.
Definitions:
Paragraph 1 says the situation (ball on ground - no tackle) occurs when a ball is available on the ground (except immediately after scrum or ruck), and a player goes to ground to gather it.
I think we are all happy about that. Covers most scenarios.
But it then goes on. Paragraph 2
It also covers when a player is on the ground in possession of the ball.
So Para 2 is saying that Law 14 covers situation when a player is on the ground with the ball, but who hasn't gone to ground to claim it (as this is covered in Para 1). So this gives us 2 scenarios. The player is already on the ground when they got posession OR the player had possession when they went to ground. It doesn't specify which - so I'll allow both.
I believe that Paragraph 2 would read: "It also occurs when a player
GOES TO ground in possession of the ball and has not been tackled." if your opinion is meant. It does not it just refers to players on the ground.
I believe that "Game is to be played by players who are on their feet" means that those off their feet cannot prevent those on their feet playing, nor can they impact those players directly (tackle). I do not believe it means they cannot play the ball - provided they comply with Law 14.1. If the "Game is to be played by players who are on their feet" was truely meant to be such a profound overriding statement, it would be in Law 7, not Law 14. It also would be the first paragraph in Law 14 Definitions as an overridding concept, not halfway down.
(And for clarification on this arguement: The argument is only over if a player on the ground can play the ball the same as a player going to ground to claim the ball can - i.e. in accordance with 14.1)
