I like that McKenzie keeps this threesome: 9-Genia, 10-Cooper and 12-Matt Toomua. As Stirling Morlock said, Wallabies have to keep a backline, is the only way to gain confidence and play safely, is what ABs make: 9 Aaron Smith,10 Dan Carter ,12 Ma'a Nonu and 13 Conrad Smith. They play with confidence.
I also like the inclusion of Timani, he's the strongest aussie player, he can push back any rugby player elite around the world. I want to see Lee Dickson facing a big opponent.
If Wallabies keep the level they had in Rosario and Dunedin, they should win this game by +10. They will have to counter the English scrum, that will be the hardest for them, if they can contain that, then they will win the game.
Cheers
