I am gobsmacked about the number of people who say rucking is banned, I really wonder where their heads are. We all talk who is off side etc at ruck all the time so it obviously isn't banned. The thing that is barred is rucking the body, or actually I think even that still legal if you doing it in backwards motion. I will also say whatever rule is made good players/team/coaches will find way to stretch them.
As a case in point look what Wallabies have been doing with Fatcat and substituting him on and off, they seem to be breaking the rules but hey noone is stopping them, so they carry on.
I will continue to say what I said when way back we used to here the old secondary runners arguments that Brumbies and Wallabies used to use, they did it all the time, if the refs considered it illegal they would have penalised them, they didn't , and what all the fools that continue to moan and groan should realise , the Referee is supposed to be the sole arbitrator of the rules in any game of rugby, I said it then and I say it now when I hear the continual whinges about Richie or whoever. I would also add there is no opinion in here that I have ever read that has lead me to believe the poster knows more about the laws of rugby than the refs. And bollocks to saying look at this frame by frame, the bloody game isn't played frame by bloody frame, it's played at a reasonably quick tempo which is why so many rules HAVE to be discretionary, or up to the ref to arbitrate!!
