New Zealand have revealed extensive plans to rotate their squad throughout the November Internationals, starting against Scotland.
Fielding relatively unchanged line-ups has become a hallmark of the All Blacks in recent years but the world champions are set to make a significant shift in policy and give their whole 32-man squad game time.
Uncapped Dane Coles and Tawera Kerr-Barlow are both likely to feature in the first two weeks - against Scotland and Italy - while Kieran Read is expected to take over as skipper in at least one of those games.
Neither the Scots nor the Azzurri have ever tasted victory against the All Blacks, who have acknowledged their plans to test their depth do not come without the risk of disrupting their cohesion.
"That's a definite danger," Read told Fairfax NZ News.
"We might not have the combinations right. It can be tough to get out on the field under pressure and get them right.
"The first few weeks create different challenges for different people. It's about adapting to that quickly."
"The squad throughout the year has been well drilled and guys have slotted in to do the job so I expect everyone to jump in and do what is expected," added Read.
Competition for places in the starting XV will be red hot for the games against Wales and England.
"There's another scrum-half around so there's a chance you may not be in the team," said Aaron Smith.
"They [coaches] are going to try some new combinations.
"When you're in the All Blacks environment it's about putting the team first. If I'm not selected, I'll be doing my best to help out Tawera or Piri [Weepu]."
