If you saw any of the Baby Blacks vs Ireland U20 last week, you will know that New Zealand rugby players tend to be bigger than just about everybody else. This tackle came from a schools game down there but could probably have be heard anywhere on earth.

In fairness to the outhalf he picks himself up pretty much immediately but you would think he would have felt the effects of the hit for a while afterwards.
