I don't think anyone is ******** themselves, just recognising that a win is not the inevitability it used to be. NZ fans also used to have a simple 2 category system to work with: we might lose to the Boks, Aussie, England every so often, and France. Everyone else was in the "we always win" category - we didn't need to worry about the relative strengths of, say, Fiji v Argentina v Italy. There was no "banana-skin" concept. They were all in the same category. Losses to Ireland and especially Argentina have blown that simple world view up. So the All Blacks supporter subconscious says "if the Pumas can beat us, why not Italy - they are the same category of opponent." We are just learning to see in shades of nuanced grey rather than black and white as to who is actually a threat.
I'm glad Jordie is playing. He got 4 tries in his last (only?) test v Italy.
