It was in Paris last year, in their final game of the 2016 season, that the All Blacks hit the wall. They looked drained almost from as early as the second quarter of the first half and it was only one magical, opportunistic play by Beauden Barrett that enabled them to hang on to victory.
With the French almost certain to score two minutes after the break to go three points ahead, Barrett shot out of the line and intercepted Camille Lopez's pass and charged 80 metres to score at the other end. It was a huge moment and had Barrett not got his timing right, the All Blacks may well never have won that test.
The All Blacks coaching staff could see their players were flat, devoid of energy and a shadow of the team they could be in that test at Stade de France. Steve Hansen came home and told the New Zealand Rugby board that his team "crawled over the line" and that there would have to be a major rethink about how they handled workloads in 2017.
They could not risk reaching November so short of gas in the tank again. They rode their luck in 2016 but might not get away with it again and one of the key goals for this year has been to end with three memorable performances in November against France, Scotland and Wales.
