@pakman Good analysis. I have 32 guys in the current squad plus Cane and Cruden minus Todd (he seems no certainty, so I have minused him initially). So there are 33 players locked in and three to be added.
I think they will take six props, and the sixth will be Hames, a LH, as they clearly prefer Tu'ungafasi as a TH currently. Crockett is the oldest All Black in the current squad and is potentially doubtful for RWC 2019 (though he mused recently that he currently felt fit enough to get there. Also, he and Moody share gametime all season long so he is not heavily raced during the season).
Ditto they need to find Kaino's successor, as a few have stated above. It seems Dixon, Squire, Luatua and maybe A. Ioane are still the candidates (also as 8 cover). It would be very tough on Dixon to axe him given he's played five minutes of test rugby in the RC. I think they'll take Matt Todd on the EOYT, and he'll start against Italy and France (Ardie on the bench for all four games) and keep Cane's workload down. That means no room for another 6/8 after Dixon and Squire. There's a huge logjam of talent there which is bad luck for some.
I don't think they will take any extra midfielders, given that SBW and (hopefully) Ngatai are back next year.
My 36th guy will be an outside back (even though NMS will be back next year), probably R. Ioane with Melani Nanai an outside chance.
