Wallabies "Steady Eddie" Falls on his Sword

Bringing in so many new young players, and discarding the experienced ones proved to be a disaster. 

The new players will probably not even be test starters in 4 years, so it is hardly a rebuilding phase to replace the most experienced players just before a World Cup. 

Australia should have started a quarter-final finish, or even a semi due to the unbalanced quarter-finals. 
Then after the World Cup, the old players could be retired- and the rebuilding phase could begin- (assuming new young players are test standard potential)
