The All Blacks are promising to pick their best available team for this weekend's Bledisloe Cup test in Perth and the biggest point of interest is whether it will include two openside flankers.
Sam Cane and Ardie Savea both started against Argentina in their opening match of the Rugby Championship but if it's to happen again, it will almost certainly force a change in position for captain Kieran Read.
The selection could also reveal a big part of their plans for the Rugby World Cup.
In June, Steve Hansen ruled out starting Sam Cane and Ardie Savea as dual opensides. There's no chance of Sam and Ardie playing six and seven but there is at seven and eight.

Using Savea off the back of the scrum worked when Kieran Read was rested against Argentina so to do it against Australia, Read would have to move to six.
There's a good chance he could be considering Hansen has said he wants to select his best available team.
Sam Cane has enjoyed his rare chances to run on with Savea.
"We chatted after that it was cool playing together," said Cane. "Because usually it's running on and swapping for each other."
If it happens, there could be four opensides starting the first Bledisloe if Wallabies skipper Michael Hooper is joined by David Pocock.
It means both teams will sacrifice lineout height and that's a major reason why the All Blacks have traditionally favoured a bigger blindside flanker.
It can be done, but will Steve Hansen do it for as big a game as the Bledisloe Cup?
