It seems - amazingly - that World Rugby's conclusions - referring to Laws 14 and 15 - we what I've been droning on about here and elsewhere for ages
recommending a strict reinforcement of existing law
If the Laws around what the tackler must do and what happens when a ruck of formed are applied - then the breakdown mainly works a lot more often than not
The guff about "on feet" or "good competition for ball" were both irrelevant if its a ruck. Only first person to the tackled player had ball handling rights and only before its a ruck, i.e. "unless they were able to get their hands on the ball before the ruck formed and stay on their feet"
Too many times in the Prem, a continued competition for the ball with hands was allowed, even when it was a ruck and when no one had hands on ball (not just pinning the player down). This then provided a clear incentive for the "clear out" - as it was virtually the only way of removing a player going for the ball in a ruck....using their hands. Either they had handling rights and had the ball or its a ruck and no hands allowed.
So - adherence to Laws and you get faster ball, lower risk to players and frankly, easier reffing
And as I've said far too often, this was the how the game was more often played and reffed in NZ Provincial games (Mitre 10) or at least the ones I watched last year.
