hahaha .. he is AMERICAN!
so, 23 yo american kid takes up "rugby" and 12 weeks later makes one of the toughest teams looks stooped hahaha
I guess this settles the rugby vs football argument

NFL is a WHOLE diff ball game when it comes to athleticism
US could ask the top NFL guys to train for a a few weeks to learn the rules and would win the 13 cup nation easily

on a side note, he is very fast even by NFL standards .. what's scarier is that he has good hands so he could play more than just corner..
