Nanai-Williams is the same. A couple of the breaks he made against the Force on Friday were from first or second receiver, where he made his way off his wing and made some scintillating runs, and then a couple of others saw him hold his position and skin a couple of players outwide.
I think it's a real bonus if a winger can play that way. Savea is without question the best winger in the country but, when you watch the way the likes of Lowe play, I wonder whether that's the next point of development for him.
Savea already has the skills and the ability - he's got good vision, he knows when to pass, he certainly has a kicking game - but we don't see him stepping in as a first receiver.
He's there gravitating towards the ruck and getting the ball but is doing that feeding off other players. I'm sure he could start to bring first receiver into his game and increase his already impressive skillset, which would make him even more devastating.
Encouraging Savea to play that way with the All Blacks, alongside Ben Smith, Corey Jane and Israel Dagg doing the same, would completely change the dynamic of the backline, giving you first receivers with all sorts of different numbers on their backs.
I also think it's the way rugby is going. You want your game-breakers with their hands on the ball as much as they possibly can. The game has evolved so much now that everybody creates for everybody else.
If you look at the world's best, they can slot in anywhere during the course of an attacking sequence, be a first receiver or second receiver or be on the end of the chain.
Kieran Read's a classic example of that, comfortable at playing on the wing or one in from the wing, and someone like Sean Fitzpatrick modernised the hooker position to play not so tight.
We as New Zealanders lead the way in terms of the skill level of players 1-15. And I think that's something now that will nearly be a requirement for a winger.
