If you want to see an all encompassing video of the sport, watch this: http://www.youtube.com/watch?v=kRpPf6rCyW4
Rugby, 80 minutes of prowess and determination. The camaraderie is unparalleled in any other team sport I have played, that includes soccer, hockey and baseball. The game is definitely underrated in North America.
I don't really like any footy and i'm not from NZ but just about any All Blacks game is worth a watch.
Teams to watch out for who tend to play a very entertaining game is the Geelong Cats (last years AFL Grand Final winners). They are going through a golden era at the moment.
That said i'm always up for a kick in the park :D
(And lest that be interpreted as me being facetious - that's a core rugby union slogan http://www.google.com.au/search?hl=en&q=the+game+they+pl... )
