After the disaster against Ireland in Chicago, and a tough return match in Dublin, the All Blacks hardly need to be warned about the threat their old nemesis France possess.
Another potential red flag for Steve Hansen's men is that it's their last test of the year - a traditionally tough one for the men who normally wear black, but on Sunday will be attired in a curious alternate strip - all black and white and zany angles.
They will almost certainly be on high alert already. They know France can be an unpredictable beast, but after the twists and turns of recent weeks, the All Blacks at least have some comfort in also knowing they are welcoming back Jerome Kaino to the No6 jersey.
Kaino's last outing was as a lock at Soldier Field, a match in which he picked up a calf injury and turned in a disappointing performance in what is an unfamiliar position. One of his main issues wasn't the set piece, however, it was in open play, and in particular being held up by the Irish pack who seemed to know exactly what he was doing and how to neutralise it.
For a 76-test All Black who prides himself on his power, that would have hurt. But the lessons will have been learned as far as Kaino is concerned, and in the wake of the citings of Sam Cane and Malakai Fekitoa for alleged high tackles, the 33-year-old is the man who can ensure the All Blacks aren't gun shy as far as their defence is concerned.
