Australia's performance in knocking hosts England out of the Rugby World Cup was an abject lesson in how to play rugby at its most skillful. England may have more players and more money than any other rugby playing nation in the world, but that matters little if the fundamental joy of how to play the game is missing.
Australasian kids grow up with a mindset to attack. The sleight of hand and creation of space at full speed that led to Bernard Foley's second try, with key roles played by Will Genia and Kurtley Beale, was something the English backline could only dream of doing.
The virtuoso 20-point win is World Cup-winning form and the All Blacks will have watched and worried. It was athleticism over brawn, fast-paced skill v robotic logic, natural ball-runners looking to score tries v forwards and penalty goals.
The Wallabies used to have a weak scrum, but no longer. They humiliated England in the final few scrums.
David Pocock's performance in winning so many turnovers at the breakdown was a master class reminiscent of a younger Richie McCaw. But England played into his hands with how slowly they moved from phase to phase, and their strange commitment to playing the pedestrian Rob Bradshaw at openside flanker. Also watch how slowly England halfback Ben Youngs clears the ball - it is almost playing by numbers and to order.
Sure the game got tight at the end, after the great Genia was replaced by the inept Nick Phipps, who nearly cost Australia dearly, but they were good value for their victory.
Their slick precision contrasted with the dross served up against Georgia by a completely underwhelming All Blacks side. There just does not seem the same fleetness of foot and sharp tactical nous.
Coach Steve Hansen and captain McCaw may have something up their collective sleeves to dazzle us in the quarter-finals, but if the finals become reliant on goalkicking we will come second, after Carter and Beauden Barrett's inept displays so far.
Saturday morning's match against Tonga is now much more important for the All Blacks than a warm-up for the quarter-final. We have to get our sharpness back and particularly the mistake-free, fast game that set the All Blacks apart.
