The most spectacular part of the All Blacks' undefeated run in the Rugby Championship have been their tries - more than six per game - plus the offloads and all their other attacking instincts with which they have wrought havoc against Australia, Argentina and South Africa.
But just as important has been their defence. They have conceded only three tries in four tests, and it comes as a genuine surprise when a team manages to get across the line.
For that they have their general hard-working attitude to thank, but also the defensive nous of assistant coach Wayne Smith, who was brought back into the fold before the World Cup and whose work is really now starting to reap benefits.
Their tackle success rate is in the region of 90 per cent - better than any other of their Southern Hemisphere rivals - although it remains to be seen how the absence of enforcer Jerome Kaino against the Pumas in Buenos Aires will affect them a week on Sunday.
For skipper Kieran Read, the attention to detail that Smith brings to his defensive role is crucial.
