On Lote Tuqiri's tackle, I will make only one point, which is that the player getting tackled needs to take some responsibility for the part they play in getting themselves in as safe a position as humanly possible when lifted off the ground.
Richie McCaw was lifted by Lote (not a lot I should add) but, instead of crunching his stomach and twisting his body, which is what you are taught to do when lifted off the ground; he stayed pencilled straight so that his head, instead of his shoulder blades, made contact with the ground. I am not condoning spear tackles but I will stand by Lote and say this was not a spear tackle but an aggressive, dominant tackle, which we are normally praised for doing. Granted it looked ugly but I would be really disappointed with the way our game is heading if Lote got suspended for that tackle.
