At the end of the day Lawrence ruined any chance of the game being a decent game of rugby, one team had the ball and tried to play, but were prevented from doing so due to the laws not being applied, not at all. Boks had their chances (however would have much more) to win the game in spite of the poor reffing display, and a cock-up from Danie Russouw gave away the last penalty to Aus to win.
Bryce Lawrence should not be reffing at even an amateur level, any non-harmful critisicm (sp) of him is fine by me. The one thing that ****** me off the most, is that Pocock got man of the match because he was allowed to operate outside the laws of the game. Some fair play to him, he played the ref, but in my books its far from ideal when professional sportsmen try to do things they no are against the laws, simply because they think they won't get caught. Its not at the same level, but deliberately taking advatange of a situation such as in this game with the rucks, is principly the same as taking a new performance enhancing drug that the authorities can't pick up.
As for your point about the 6/7 doing the same, its a different thing when you are the attacking team trying to get ball than a defending team trying to spoil it.
