Kieran Read, who emerged in the McCaw era, has been a disciple of the performance-first philosophy and last year produced a number of stunning solo moments in times of need for the All Blacks.
But with Read — recovering from back surgery — not likely to return until July, the All Blacks must take on France next month with a stand-in captain who will be named tomorrow.
The short list comprises three names: Ben Smith, Sam Cane and Sam Whitelock. All three meet the quality player criteria.
Smith has been spell-binding for the All Blacks since 2013; the sort of player who has gathered admirers around the world for the way he finds a way to be influential.
He'll be 32 when the series kicks off, hardly ancient but old enough to believe his playing days won't extend much past Read's and hence he's not an investment in the future.
Besides, modern coaches are resistant to the idea a fullback or wing can captain a test team and Smith's value seems to be as an able and willing deputy.
Which leaves the two Sams, both of whom have captained the All Blacks, both of whom are in great form and both of whom are likely to be playing test football long after Read has said farewell.
All Blacks coach Steve Hansen could justify picking either as captain.
Cane, 26, has the potential to establish himself as a great All Black. He's grown immeasurably in the past 18 months and has convinced a once sceptical public he's a world class openside.
No one in New Zealand tackles harder than Cane. No other No7 is as combative and imposing and he has shown himself to be a mature and assured captain of the Chiefs this year.
He's led the side mostly on the strength of his work rate, discipline and defence but there have also been times when his decision-making has been excellent and tactical awareness obvious.
Cane has made a strong case, shown he's ready and yet for all the boxes he can tick, Whitelock can tick more.
Whitelock has been playing with such authority and presence for the past two years that he carries himself with the mana of an All Blacks captain.
He is the world's best lineout and aerial lock. He is, best anyone can tell, an engine with big horse power in the scrum and he clatters bodies in the contact zone.
He's also become more of an impact player away from the set-piece, regularly winning turnovers, making dainty offloads and carrying the ball harder.
Whitelock was rightly named New Zealand Player of the Year in 2017 and is playing every bit as well this year.
He is, without question, a player who can lead by performance. But he's also developed that invaluable art of staying calm under the most intense pressure and explaining to those around him exactly what he wants them to do.
There was no better example of that than last week's miraculous 31-29 comeback win by the Crusaders against the Waratahs.
At 29-0 down, as they were after 30 minutes, they could have imploded and yet Whitelock had the confidence to gather his team around him and demand that they retain faith in the game plan, but just tone down the risky offloads and 50:50 passes to build some continuity.
He put the emphasis a little harder on retaining possession but not at the expense of playing their natural game and three tries came in eight minutes.
It wasn't just what he said that changed the game, it was the way his body language oozed calm even when it felt like the game was just about over for them.
There was not a hint Whitelock was worried by the situation and seeing their skipper so composed and untroubled had an enormous impact on the young Crusaders around him.
It was strong and inspiring captaincy that was bolstered by the role he played in winning lineout ball and through a combination of his age, his form, his experience and his ability, Whitelock stacks as the right man to lead the All Blacks against France.
