If they were that good they wouldn't bottle it when it counts. Every. Single. Time.
This free flowing, broken style of play may be superb to watch when in it works, but a the disorganised mess needs a huge element of luck when the pack donesn't front up or the back three choke underneath high balls;
The ABs vs Boks in the 3 Nations this year wasn't taken seriously by SA, so it was a pretty miserable, near 2nd string, side vs a bunch of 15 (highly talented) individuals wearing the same black shirts. Yes, the AB's won that. Hurrah for then.
Come World Cup time, the ABs get one difficult opponant the whole tournament and went into the game with a level of arrogance that they'd simply waltz through the French. The French however regrouped, played as a team and low and behold, the World ranked no. 1 side who everyone expected to win the whole thing didn't even reach the Semi finals. The big upset occoured, that is a great thing for a tournament.
The same with England v Convicts; Wallabies pride themselves on this "fast flowing, free rugby" and seem to think they don't need a pack (being a they're all part time league converts (insert NRL jibe here) therefore don't understand the basics of contesting a ball). What happens? The Formula 1 cars of Australian Rugby find themselves in a tug of war contest against English bulldozers and wrecking balls. England, ranked eight in the world knock out Aus, ranked 2. Another big upset, another win for world rugby.
(By the way, what do you call the 7th vs 8th place playoff in the Rugby World Cup? The Bledistloe Cup!)
Argentina, everybodys hero in this tournament did the same against France and Ireland. Fiji did it against Wales. Japan attempted it against Fiji. Portugal did it against The ABs (and scored a try) and Romania.
The only side to combine the pack and the backs is South Africa, who only can claim so because Habana runs away from everyone except rookie Yanks to score. Otherwise, they're a side with a devistating bunch of fatties, a little gobshite scrum half in the shape of Du Prez, and finally Percy and James banging the ball downfield for the teratory.
It may not have the "style" of the ABs, Aussies or Wales, but the forwards game which has dominated this World Cup has been a hark back to the golden days of real men playing rugby. Forwards win a rugby. Backs only decide by how much.
