And it's that last point which is the most salient as the All Blacks prepare to touch down in New Zealand.
They know who they are.
There is nothing contrived about the All Blacks. No one has to wonder what it means to wear the jersey or try hard to find the pride in it all.
Much of that is down to the power of the legacy. More than 100 years of sustained excellence will do that - give the nation a good feel for what it's all about and what's expected.
New players arrive and they don't really need to be told, in the broader sense at least, the history of the brand. They don't need to sit down and have it explained that it is quite a big deal to have a test jersey in their kit bag and how they should feel about that.
If England's troubles could be summed up quickly and neatly, their lack of understanding as to who and what they are is perhaps at the core.
National identity can't be contrived. A wall with so-called inspirational quotes on it feels superficial and forced. How does that even work? Are players expected to sit and look at it and then feel more English?
This isn't about being unduly unkind, it's to illustrate the natural advantage the All Blacks have.
Perhaps New Zealanders don't often realise how other nations struggle to foster the same sense of understanding and connection.
Nor is it often fully appreciated how important that knowledge and understanding is.
Maybe before they leave, the All Blacks could write on the wall of inspiration: "Be yourselves".
It's worked magnificently for the New Zealand team.
