Yes very sad, I think the red card issue has been put to bed by most of us, I made a point earlier in the thread I will reiterate, If you play by the letter of the law for one thing then you must do it for all laws, I quoted the breakdown, when is there a breakdown without players infringing, Hands off, roll away, stay there, ruck is formed, every breakdown you hear this, if the refs played to the letter of the law then it would be a game of penalties, Tipping in the line out, attacking a player while in the air catching a ball, high tackles, all as dangerous, but interpritation is given the benifit and very few red cards are given.
Warbs tackle because there was no intent on harming the tackled player, Interpretation must play a part, he was not driven into the ground but let go, let go because he is an open side flanker and his priority was to claim the ball, you must also remember that warbs head was in his middriff he was probably unaware that he had turned over. In my playing days if I had made a tackle like that it would have been high 5s all round,
What I will say is Warburton is an excelent player, is not a dirty player, one day will be a great player, this would have taught him a great lesson, which he will take on board for sure.
