I wonder how Smith compares with other great Aussie flankers like Col Windon? Surely Smith has to be up there with the best. I don't know whether he was greater than Poidevin. He was more naturally talented than Poidevin - better passing and catching skills. And Smith could put people into space as well. Poidevin was fitter and more fiesty.
I don't know whether he retired too early or not. I agree with Voltman that he is passed his best now. He also had some bad games last year. I remember he should have been yellow carded in the Auckland game for killing the ball when the All Blacks looked certain to score a try. In any event the penalty was awarded and the All Blacks took the lead after that. The next week he actually was yellow carded against South Africa for doing something I can't recall, but I remember it as being diabolical. Against England we went missing and Moody outplayed him - a bit of a shock.
Then again I think the competition he had with Pocock was good for Pocock, in the same way competition with Waugh was good for Smith. And Pocock, while brilliant in the Irish and Welsh games last year (and he should have played against Scotland), hasn't really done it against New Zealand. McCaw was rightly awarded MOTM in the Tokyo Test.
Australia is choc-full of players who are greater against NH teams than tri-nations teams. Latham did some freaky things against teams like Scotland and Wales, but only scored two tries against New Zealand in his career (and look at how many tries he scored). Giteau is the same, he usually plays well in the NH - ignoring the Scotland game last year, he was terrific against Wales. No wonder he's so overrated there. But against New Zealand he stands too deep, runs laterally, and rushes his kicks that go to no where.
Big question mark over how good Pocock will be next year. He needs to step up in the tri nations. If he does Australia will be better off for having Smith retire, because they need to go for the youth right now (Digby over Mortlock, Pocock over Smith, ANYBODY over Sharpe).
