When the squad will be announced?
I think an extended squad could be like thiks
Props: Alexander, Kepu, Robinson, Slipper, Palmer
Hookers: Moore, TPN, Charles, Fainga'a
Second rows: Horwill, Simmons, Jones, Pyle
Backrows: Higginbotham, Pocock, Gill, Palu, Elsom, Samo, Dennis, McCalman
SHs: Genia, White, McKibbin
Inside backs: Barnes, Ashley-Cooper, McCabe, Horne, Cooper, O'Connor
Outside backs: Beale, Ioane, Morahan, Kingston, Gerrard, Cummins Mitchell
IMO
Alexander should be on the bench as he can cover both loose and tighthead, but he's not a pure tighthead, much better Kepu there.
We're gonna see Charles against Scotland I think, he's performing very well for all SR, deserves to be called
Troubles in locks: retiring Sharpe and Vickerman's injury have left a big hole in lineout and much more in tight play as Vickerman is vital for his hard hitting game. Hugh Pyle should be there, he manage lineouts very well, and Luke Jones too I liked him for all SR season, great talent, someone says that he's better at 6, but IMO Wallabies need his game as 4.
Dave Dennis should be 6 with Higginbotham 8 and Palu on the bench. Elsom is nowhere near to a match-22 jersey.
Big dilemma with Gill away with U.20, hope Deans won't forget him for Rugby Championship! He's better than Pocock at the moment, and now Wallabies need more a Gill than a Hooper.
Genia is back in form, Nic White played so good for all SR, McKibbin is the 3d option, still better than Phipps.
Barnes is not playing good, well... he's playing very bad, but he was doing so exactly a year ago, but when Deans trusted him (too late IMO) at RWC he was outstanding. Cooper is on his way back, but 10 jersey now belongs to KB!
Looking forward for the centre pairing: I love AAC at 13, but as I said milions of times before he can't play alongside McCabe (or A Fainga'a), too similar, if Beale will be 10, I'd go with Barnes 12 (waiting for JOC) and AAC 13.
Otherwise I'd try the current 'tahs pairing, with AAC 12 and Horne 13.
For the back 3, AAC is still primary option at 15 if Beale would be at flyhalf spot; Ioane raised up his level in these last few games, Mitchell still recovering and looks it's gonna be better than expected, Kingston and Cummins deserve a call, and, IMO, Morahan.
He's a better option than Shipperley, he can cover 11-14 and mostly 15, his kicking game is better than anyone bar... Mark Gerrard. He's been outstanding in this SR, who knows if he's gonna be selected, he was doing good also in 2011 SR, got his chance against Samoa but didn't do well. Hope to see him tested again!
