There are few, if any, better impact players in the world than Beauden Barrett but loose forward Ardie Savea showed in the first test against Wales that he could soon be considered near the same level.
In the 20 minutes he played off the bench in his debut test, Savea proved he is comfortable on this stage, that he can play with the same power and explosiveness he does for the Hurricanes, and that he and Sam Cane could prove a formidable partnership in the years ahead.
The world champions don't consider rugby a 15-man game; it's a 23-man game now and, as coach Steve Hansen said afterwards, the challenge for every other nation is to show they have the same depth in their squad as the All Blacks.
As an impact player, the 22-year-old Savea has the ability to replace Cane, or perhaps Jerome Kaino, or even a lock, with Kieran Read moving from No8 to the second row. It all depends on how the All Blacks want to play their hand and in Savea - who has the strength of a forward and pace of a back - they have an ace up their sleeve.
Afterwards, Wales coach Warren Gatland said: "They just keep coming at you. I've experienced that as a player in the past. You're playing against a team that are used to playing at a higher level and they can continue to put you under pressure for longer spells.
