I'm really loathe to have a pop at anyone on here - its a great vehicle for discussion and debate; but this is just daft.
NKW - Have you ever played the game? In playing terms, the difference between Lawes' fantastic tackle on Jackson (thanks for the vid - superb technique and great defence) is EXACTLY the same as the tackle on Plisson. Lawes commits, head down, as both players have the ball in their hands. He smashes both. In one, the ball is just about leaving the hands, in the other, its just about left. Both are example of great committed defence.
And I play as a fly half!
Those tackles for me show everything about the game we all love. Don't get me wrong, I don't want to play (or referee) RL where high shots, shoulder charges and really dangerous play, deliberately and intentionally designed to take the opponent off the park, go unpunished. Those tackles are not that. They are examples of good technique (unlike Leigh Halfpenny with his head the wrong side - far more dangerous) and good defence. In both cases, the BC got smashed, and stopped running down that channel for the rest of the game. It's up to a good fly half to avoid defenders like that, OR draw defenders like that to create space outwide. End. Of. Story.
