Kris Shannon looks at four areas All Blacks coach Steve Hansen will need to address following his side's shock defeat to Ireland.
1) Discipline
The most glaring area of deficiency to emerge from the defeat. While Ireland certainly deserved their victory, they received a huge helping hand from an opponent eager to afford them as many extra opportunities as possible. It wasn't just the potentially pivotal yellow card shown to Joe Moody in the early stages - the All Blacks heard the referee's whistle throughout the game and the lopsided final penalty count of 12-4 was a match-winning margin.
