I'll have a turn at this.........
Last RWC Cheika went with 2 XV's (plus one) due to the tight turnaround between the Uruguay and England matches.
I'm not sure if we'll go with the same strategy again - it will depend on the draw.
PROPS: Sio, Kepu, Tupou, Robertson, Ala'alatoa - this is pretty much a lock, barring injury.
HOOKERS: TPN, Uelese, Fainga'a - Fainga'a is obviously rated by the Wobs' coaching staff, and I feel like his form trajectory will see him overtake BPA (whose lineout throwing has been gash), and Latu, who would be next cab off the rank and a strong possibility depending on Uelese's return to form
LOCKS: Coleman, Arnold, Rodda, Simmons
BACKROW: Pocock Hooper, Tui, Samu, Naisarani - I wouldn't be surprised to see Hanigan there, but I don't rate him as he lacks effectiveness. If Dempsey returns to form could take the place of Samu or Timu. And I've left out McMahon as Reg seems to believe he's unlikely to return.
SCRUMHALVES: Genia, Phipps, Powell - Just like our props this is pretty much locked in. But we might only opt for 2 scrumhalves and take an extra outside back.
FLYHALVES: Foley, To'omua - granted the rumours about To'omua are true. There's really no one else.
CENTRES: Beale, Kuridrani, Kerevi, Rona
WINGS/FULLBACKS: Folau, DHP, Korobeite, Hodge, Banks - That last spot will come down to Banks or Maddocks, but I think Banks is ahead of him at this stage.
