Some years ago I was on a Buenos Aires layover (Luiz, did I come close to spelling that right?) and the South African Springbok rugby team was staying at the same hotel. I stood next to a few of them in the lobby while we waited for our room assignments. They were big guys no doubt, but not as big as most of the NFL guys I've seen up close.

Of course, being only 5'9" myself, they all look pretty big to me!
