One of the more needy and self-aggrandising posts I've seen for a while. Although I do like the way your on a first name basis with so many of the boys, it's nice to see that personal touch.
Inman, Kerevi, Rasolea, Godwin, Kuridrani, AAC (Adam Ashley-Cooper), To'omua, Lilo, Horne, and Fainga'a are all - without wanting to get all homoerotic and excite the reactionaries on here - plenty hard.
I guess it all comes down to how you feel like defining hard, or centre, I suppose. If you think Robbie is hard because he hangs out on the wing and makes one run every 15 minutes because that's all his heart can take then fair enough. As for Charlie hasn't he played one game at 13 this season? He's a good ball carrier, and a good fullback/wing but hardly a legendary hardman in the middle of the park.
If you're trying to say New Zealand pretty generally produces better players than Australia then, well, you're right. I'm sure they're eternally grateful for your thoughts that got them there.
