For me..... A team that triumphed over France on their home turf, Beat England and The All Blacks certainly stands out as the BEST in the world. The World rankings also suggest that they Best in the world. The loss to Ireland was down to wayward kicking from the Flyhalf Libbok.None at all. Just an opinion. Well done SA for winning it. Why would there be sour grapes? I'm not from NZ and didn't think England were anywhere near good enough.
Who else would you want them to beat to be considered the best.
