It is perhaps appropriate that the All Blacks will face France in their first test back in Wellington after their loss here to the British & Irish Lions nearly 12 months ago, their first at home since 2009.
No team have the capacity to surprise the All Blacks like the French, and it was that (for the All Blacks) devastating 2007 quarter-final loss in Cardiff (which came following the 1999 semifinal horror at Twickenham) which forced Steve Hansen and company to re-evaluate their approach to the game and in particular their ability to react to the unexpected.
A major one is the loss of personnel, but it's not confined to that. The All Blacks specifically prepare for losing players to yellow and red cards – and many around the world would say that was a good thing given they were the equal worst offenders last year, with eight yellows and one red.
In 2017 that tally included two yellows in two separate tests but the All Blacks scramble to make up for the numerical disadvantage as well as any team in the game. They had prepared to lose a player during the World Cup final against Australia in 2015, but the fact that it was fullback Ben Smith who received it did catch them a little by surprise, and they conceded two tries before storming back again.
The point here is that the All Blacks take nothing for granted; flanker Sam Cane, for instance, studies his loose forward opposites for trends but not too much least he assume anything during the match. Expect anything, assume nothing, is their mantra.
