In my opinion, the following players are definitely going to New Zealand:
Hookers: TPN, Moore, Fainga'a
Props: Alexander, Kepu
Locks: Horwill, Simmons, Sharpe, Vickerman
Flankers: Elsom, Higginbotham, Pocock, Hodgson
Eights: McCalman
Scrumhalves: Genia, Burgess
Flyhalves: Cooper, Giteau
Centres: AAC (Adam Ashley-Cooper), McCabe, Fainga'a
Wingers: O'Connor, Ioane
Fullbacks: Beale
With those 24 locked in, there's 6 spots up for grabs, most of which will come down to injuries. If Deans goes for the traditional split of players per position, then there's still room for the following:
1. Props x 2
2. Number Eight x 1
3. Flyhalf/Inside Centre x 1
4. Outside backs x 2
So who are the candidates? Well, as I said, those final few unconfirmed positions in the 30-man squad will largely be determined by injury. Currently, a large proportion of what would ideally be our match-day 22 is out and will see very limited game time until the World Cup actually begins (TPN falls into this group, but I think that Deans is going to take him over, regardless of whether he's at 100%, 80% or 60%). If all of our injured players miraculously come through before September, then I expect the following players to round out the squad:
Props: Robinson, Slipper
Number Eight: Palu
Flyhalf/Inside Centre: Barnes
Outside Backs: Mitchell and Horne
Within the group of named 'shadow players', I expect Lachie Turner to be next in line if any backs don't come through, Phipps to come in if Burgess goes down, Samo to cover the loose forwards, Timani to cover the locks, Ma'afu to cover the props and Hanson to get the call up if any of our rakes go down.
