The Richie McCaw theory of captaincy is to aim to be the best player and go from there, something that Kieran Read should be able to emulate this week.
Read, who will take the captaincy now - probably through to the end of the Rugby Championship - needn't get caught up trying to make rousing speeches or influencing referees.
He'll be inspirational and hugely effective by playing as well as he did in Hamilton where he was thunderous in the physical business of carrying the ball and knocking people down.
There are a few good No8s in world rugby at the moment - Jamie Heaslip, Toby Faletau and Louis Picamoles - but none quite in Read's league. He's like Dan Carter in that he has the complete portfolio: that rare ability to do everything - ball carrying, tackling, winning lineout and kick-off ball and scavenging.
He can be dominant in tight encounters as he was against Argentina and world class when the tempo is high and he's roaming wide as he did in the first two Bledisloe encounters.
