The All Blacks have rarely tasted defeat over the past four years but can't get too comfortable, writes Scott Stevenson.
The All Blacks talk a lot about learning from success, not that they have much of a choice. Over the last four years, they have built a winning record that is scarcely believable in the age of professional sport - 47 tests, just three defeats. That's a lot of success to learn from.
The standard line, however, is that you learn from your losses; that you remember the uncomfortable moments, and the searing pain of finishing second, and then you use that to motivate you in ways victory never can.
Pain has been in short supply for this team over the last four years but, in the history of World Cups, the All Blacks have a reservoir of residual discomfort to call upon. They will know this - none more so than their head coach and captain, for whom 2007 remains a wound still not completely healed by the home victory in 2011.
In 2011, the All Blacks had the chance to repeat history. In 2015 they have an opportunity to create it, by becoming the first team to win consecutive Rugby World Cups. "That's the mountain we want to climb," said Richie McCaw in a recent interview.
