Steve Hansen's formula has been working for so long it becomes churlish to keep suggesting they are doomed. Men like Hansen work under extreme pressure, and they deserve the plaudits when the scoreboard demands it.
We the sceptics will stay quiet, and settle maybe for a light dance on the grave while accepting it is difficult knowing when to let go of legends such as McCaw, even if those calls come with the territory. In McCaw's case, some of us clearly see what he isn't doing anymore, while others still marvel at what they do see. The debate is definitely on.
But whatever that verdict, it wasn't Hansen who dropped the ball in Dunedin. If a test series win was the main mission, Lancaster made the blunder of blunders shifting Manu Tuilagi to the wing for the second test after he did a reasonable impression of his 2012 demolition job at Twickenham in the first. Much is made of All Black centre Conrad Smith's rugby intelligence and fair enough, but that high IQ has been laid low by Tuilagi twice in three years. Yet Lancaster went out of his way to spare the All Blacks in Dunedin.
No coach hell bent on a series win, and in his right mind, would have come up with that choice. Modern test coaches have a constant sanctuary - World Cup experimentation and preparation. Had Tuilagi been in his rightful place, England would have seriously damaged the All Blacks early in the piece and had a fair old chance of starting to change the world rugby order. Instead, Tuilagi blew a winning position through a lack of pace.
The after-match at the outstanding Forsyth Barr Stadium summed it up. The English captain Chris Robshaw was dragged away from a conversation to take the stage, where McCaw was presented with the Hillary Shield.
Sir Ed had gone to tremendous lengths, or heights, to give them something meaningful to play for, but the shield doesn't get close to the Webb Ellis Cup mountain top. Even on stage, Robshaw looked mildly distracted, his attempt at feigning despair being the depressing description - for any sporting romantic - of working in a results-based industry. What he really meant was for this English side, some results are far more important than others.
