I reckon they're a bunch of sooks Copago. You never see too much bad sportsmanship from the Aussie team......unless they're getting beaten or under pressure. They then start acting poor little rich kids that had their Mercedes keys confiscated by dad.
In cricket, like all sport, winning is an extreme attitude. Sledging is a part of the cricket psych and Australia take full advantage of it. It should never cross certain boundaries but it does at times, when the pressure is up. It needs to be erradicated and disgracing Lehmann might not be a terrible thing for the game. I'd hate to see sledging go completely.
Here's some excellant sledges from days gone by. I put it in Jokes and Humour
