England reckoned that had Manu Tuilagi been fit to play the All Blacks, the outcome at Twickenham may have been different.
The 22-year-old centre was the architect of England's 38-21 victory a year ago and is an undisputed, powerful ball-carrying and line-breaking presence.
But just as Billy Vunipola is no Kieran Read, Tuilagi is only half the player Ma'a Nonu is. Maybe not even that and it's by making these deep individual, analytical comparisons that the current superiority of the All Blacks can be best explained.
Just as he's hugely misunderstood as a person, so too is the essence of Nonu as a player not fully grasped. His core role with the All Blacks is to smash his side over the gainline - smash the other blokes behind it. The heavy focus on collision work creates an impression - that he's a battering ram, a player without a wider skill-set or much in the way of subtlety.
The All Blacks will gladly let the world think that, for it couldn't be more wrong. Ask any of the All Black backs who has the best hands in the side and most would say Nonu. His basic handling is better than Daniel Carter's and only Aaron Smith throws a better long pass.
