"We talked a lot earlier in the year that when you cut down the big trees, the little trees tend to get the sunlight and grow. That's what's happened. The guys have been prepared to step up. Our great players cast a big shadow. Once they go, then everyone else says, 'well, it's my turn'."
There are few cliques, but there are groups based on positions: front rowers, loose forwards, inside backs, midfielders, outside backs, and so on.
Flanker Jerome Kaino spoke the day after the World Cup final at Twickenham in November about the loose forwards challenging themselves to reach new heights in the playoff matches. Significantly, the first tackle made against the Wallabies in the final was a huge hit on dangerman Israel Folau by Kaino which set the tone.
The midfielders - Ryan Crotty is back in the No 12 jersey following his return from concussion, and will partner Malakai Fekitoa - have seen more change that most, but Anton Lienert-Brown's test debut against the Wallabies in Wellington was one of the more assured in recent memory. That was helped by the support he received during the week from the collective but most particularly his midfield teammates and rivals.
"The awesome thing about this environment is that everyone really helps each other," Crotty said. "I remember when I first came into the group and the senior players helped me out a heck of a lot."
One of the traditions Crotty, Fekitoa and company have is a cup of green tea during the week.
"Actually, it might be a coffee before training. We'll catch up and go over what we think is really important for training this afternoon and then leading into the game."
The performances during the All Blacks' five victories this year - three against Wales and two against Australia - have also been primed by good performances on the training pitch. And it's here where standards are just as high as on match day.
Hansen said: "On the training park, we've been training particularly well. We've been setting our week up well and there's no complacency, or there doesn't appear to be, and the guys are living and driving the standards that we aspire to.
"We're not the finished product. The more experience we get, this group, the better they will be."
