I'd back all those four to come good for the All Blacks. But their form isn't collectively there.
Sam Whitelock and Brodie Retallick have been playing well, so it would be a case of carrying on with them as they are.
But for that back five to deliver, they need the front row to be setting the platform and who, of the men at the All Black training camp, has been playing well?
The Franks boys have been all right but not much more than that. Neither Tony Woodcock nor Charlie Faumuina have been doing too much certainly they haven't been setting the world on fire - and Wyatt Crockett is perhaps lucky Tim Perry was injured earlier in the year, otherwise he might not have had much of an opportunity.
None of them are in great form or even particularly good form. But again, there is experience and talent there to be confident they will deliver.
The position of hooker, though, is different. Age catches up with everyone and I feel it has with Keven Mealamu.
Lovely man, great All Black ... but I think the time has come for him to hand over the reins to Dane Coles.
The reality might be hitting Mealamu now. Not even his throwing is holding up that well and it might be best for the All Blacks to start developing not just one young hooker but two.
