The niggle continues even as the All Blacks continue their marvellous unbeaten stretch.
It's not a complaint, more of a misgiving, a twinge about their ability to go the distance. Not the immediate target of equalling the world record for 17 consecutive victories this week in Hamilton, rather the last lap of the quadrennial race to the next World Cup.
Delivering such an observation suggests carping for the sake of it.
However, the All Blacks are always about improvement, their mantra is always to go to the next level, to work on the pieces of minutiae which go into the grand puzzle of international rugby. They will have rewarded themselves with a good night in Dunedin and celebrations about repelling a strong England side and, once they settled, delivering plenty of strong quality rugby.
