The big decision comes down to who you start, because Barrett will be in the squad somewhere. You don't need two first-fives if he is covering on the bench, but has he done enough now to earn a starting spot?
Potentially Damian McKenzie could get a debut as cover at fullback and first-five but realistically, who would you leave out?
It's less complicated at second-five. Charlie Ngatai and Ryan Crotty are the key challengers to replace Nonu. They will combine with Malakai Fekitoa, the logical contender at centre.
Sam Cane has been groomed as the No.7-in-waiting to replace McCaw - but Matt Todd hasn't been bad either. Nor have Ardie Savea and Blake Gibson, although the Olympic sevens and injury could rule them out respectively.
At No.6 Jerome Kaino is likely to remain the incumbent but Brad Shields and Elliot Dixon loom as contenders. As with any loose forward trio, it will depend on how they complement each other. Do they want blindside/No.8 or blindside/lock cover?
Elsewhere, the tight five should largely pick themselves based on last year.
The only debate at halfback is who backs up Aaron Smith from TJ Perenara, Tawera Kerr-Barlow or Brad Weber. Weber is a livewire, and similar to Smith in many ways, so could be ideal to bring on to up the tempo.
Out wide there are few problems. Ben Smith plays fullback and, while there were concerns over Julian Savea's fitness, The Bus seems to have got that right in the past fortnight. He just has to keep working on it.
At 21, Tevita Li might be worth a go on the other wing. He would probably go up against Patrick Osborne whose age of 28, might present a barrier. Alternatively, wing might be another way to bring McKenzie into the mix if Smith or Barrett shift accordingly.
