The side effect of being consistently good is that it creates a burden of expectations. Or maybe the cause of being consistently excellent is having to always carry this burden of expectations.
Whatever the cause and the symptom, the All Blacks tread, again, a fine line in Paris.
They have had, so far, an incredible season winning as they have 12 of their 13 tests.
There has been plenty of good rugby - great rugby- along the way, as well as the Bledisloe Cup, Rugby Championship and world record of consecutive wins.
And yet, for all that, if they lose tomorrow morning against France, their season will carry the worrying sense of things not being quite right. Thoughts about this side will change quickly and almost ridiculously, from some people bemoaning the All Blacks' dominance in September, there will be others fearing for their future by December.
