So there are two more rounds until the initial squad of 25 is announced. The only thing the initial squad means on an absolute level is that those 25 players won't be allowed to play in round 17 (Brumbies vs Rebels, Force vs Tahs, Reds vs B&I Lions). After the 25 man squad is announced on the 19th/20th of May, those players will still have two more Super Rugby games before camp begins properly. Presumably there will be another logistics camp or just talking with the players about what is expected in the interim.
You would figure that players returning from injury will be left for the final 6 places (if they are selected at all). I'd include at least Barnes and McMeniman in this and possibly McCabe as well. Presumably players like Cummins will be trying to nab one of these spots and maybe also Cooper (he could be given a chance to play against the B&I Lions for the Reds to see how he goes if Deans is holding out on picking him).
For the intial 25 man squad, I think we'll see:
Robbo, Alexander, Slipper, (Palmer or Kepu)
Moore, TPN
Horwill, Douglas, Simmons, Timani
Palu, Hooper, Smith, Higginbotham, (Mowen or Dennis)
Genia, White
JOC (James O'Connor), Beale
Lealiifano, AAC (Adam Ashley-Cooper), Tapuai
Folau, Ioane, Tomane
So that's 25 players.
I think Barnes, McMeniman, Cummins, McCabe will be given more game time to try and prove their fitness and/or gain some more match practice.
Players like Sio (and whichever out of Palmer and Kepu get left out), Mowen or Dennis (whichever one gets left out), Mogg and Cooper will be fighting it out for the last couple of spots in the 6 that are added to the initial squad.If some of the players returning from injury don't make it, it will give a chance for more of the bolters to get selected. You could potentially add To'omua, Foley, Pyle and Godwin to that list.
Potentially Beale could be left out of the initial squad so he has an extra game to get his match fitness up but I'm guessing Deans will be happy to name him in two weeks time given how his fitness looked against the Chiefs.
I'm unsure whether the final squad will have three hookers and three halfbacks in it. If it does, you'd assume that Hanson or Fainga'a and Phipps might get added in that final 6 players. You'd think that the initial squad of 25 won't have three hookers and three halfbacks in it.
