I do admit that I respect his status as the smallest guy ever (in tests) to employ the Maori sidestep as his number one attacking weapon. As the vid shows, if you can survive doing that every week for a decade, sooner or later guys will miss a tackle and you'll be in!
Also winning a world cup probably does mean you're not completely terrible, but it dosen't necassarily mean you're awsome either - remember Butch James is in the same catagory. He was an OK player, ran straight and hard and usually kicked his goals, improving under pressure as he got older. Defensive liability though, and makes my top ten because he's been represented as god's gift to rugby in some quaters, which he clearly was not.
