Aside from one break against Biarritz and another against Scotland, I don't think Peter Stringer ever ran with the ball in his long, long career. And what were the incredible tackles? A tap tackle against Lomu, another against Jason Robinson...anything else? And yeah, a scrumhalf that passes well - that's not exactly a rarity. Just because I don't have a professional career doesn't mean he's a great defender or attacker.
Some will say that it's ridiculous that he was suspended for something so unimportant. I'd be more inclined to say that it's ridiculous how stupid the guy must be to get himself suspended for something so unimportant.
Sorry, but no. If someone pointlessly clotheslines you when you're going in for a try you have a right to complain. In fact, you shouldn't even need to complain, because the referee should see it and deal with it himself without needing it to be brought to his attention.
