This is another reason I love football, there's no other sport like it.
American Football, Australian Football, Rugby League and Rugby Union are all too similar, and Baseball, Cricket and Rounders are all too similar.

And that brings me too Basketball, it's the only Americanised team sport I have any time for, I don't know any of the players or anything, but watching Basketball at the Olympics was great (But football is still a million times better ).
