Let's start with a couple of facts and then a couple of questions as the dust continues to settle around Chicago's Soldier Field on this day of all days.
Ireland clearly deserved to beat the All Blacks. In their first test since the death of former international and Munster coach Anthony Foley, they tapped into something special in the late afternoon sunshine, forming a special "No8 tribute" for him when fronting the haka and then playing like men possessed, but crucially with heads screwed on.
They played with heart - and there's plenty to like about that - but they also played intelligently, and, crucially, with ambition. That always makes a loss slightly easier to take. They didn't kick the All Blacks into submission, they scored five tries against one of the best defences in the world.
The result proved that there isn't that big a difference between nations in international rugby after all, and the All Blacks' run of victories, described by some as "boring", has come to an end.
The men in green have beaten the world champions. And the reaction in New Zealand was... joy? Respect? Relief for the Irish? Certainly, it appeared to be more good-humoured than the plain grief which often follows an All Black loss. Have we as Kiwis matured a little? Are we more united around our team after their efforts in winning back-to-back World Cups? Or is it the fact that this wasn't a test with the William Webb Ellis Trophy on the line? One can only imagine the difference in reaction had Ireland beaten the All Blacks in a World Cup knockout match.
