Evidence about the layers of All Black quality came through the performances during this month's series with France.
It was most noticeable in the loose-forwards where the challenge is to find the best combinations to take over from that peerless group of Kieran Read, Richie McCaw and Jerome Kaino who led the All Blacks through the 2011 and 2015 World Cup triumphs.
New Zealand is blessed with ample choices who compete strongly on the international stage but the trick has been finding the most complete blend of talents and getting them all on to the park at the same time.
Captain Kieran Read was out of the reckoning because of injury and the experienced Sam Cane was underdone after a lengthy layoff while Liam Squire had not played a great deal after breaking his thumb.
Cane got past some blood-bin damage then being subbed in the opening test but struggled to back up at the Cake Tin where Squire damaged his shoulder. That toll exposed the backup which was a level down on quality.
