If Deans has shown anything during his tenure as Wallabies coach, it's that he's extremely loyal and that he's very set in his ways. His 3N squad will be heavy on forwards, and he'll only take 2 hookers and halfbacks and rely on those two not to get injured. He'll probably take a lot of loose forwards, and I think that's a good idea as he has a big, albeit positive, selection dilemma on his hands. With players like Samo, Hodgson, McCalman, Higginbotham et al. pressuring the established trio of Elsom/Pocock/Palu to maintain their spots.
My predicted 3N squad:
Stephen Moore, Saia Fainga'a
Benn Robinson, Ben Alexander, James Slipper, Sekope Kepu
James Horwill, Nathan Sharpe, Rob Simmons, Dan Vickerman
Rocky Elsom, Scott Higginbotham, David Pocock, Matt Hodgson
Wycliff Palu, Ben McCalman, Radike Samo
Will Genia, Luke Burgess
Quade Cooper, Matt Giteau
Berrick Barnes, James O'Connor, Adam Ashley-Cooper, Rob Horne/ Anthony Fainga'a
Digby Ioane, Lachie Turner, Rod Davies
Kurtley Beale, Cameron Shepherd
