Soccer = slow Hockey minus the fist fights (Soccer is hard to watch when you were brought up playing American Football).
Australian Rules = Awesome to watch.
Rugby = Also pretty good but the Australians got it really right.
American Rules Football = Awesome (but I've seen so much that I gave up caring fifteen years ago).
Cricket = A bug.
At this point, I get bored watching most team sports (Football, Soccer, Hockey, Baseball, Basketball).
I can still watch the Tour de France and enjoy it, I can watch some mixed martial arts fights, surfing contests, some motor racing sports, motorcycle stunts.
These days, my viewing of sports on video seems to more geared toward "people are amazing" videos on YouTube, where you get to see the crazy things that are going on out there with people who are finding cool stuff to do that is a bit more on the fringe.
I've played the three codes, soccer, rugby and aussie rules. By far the most fun is aussie rules. Also watching live it can't be beaten. It is a 3 dimensional game, with the height factor used more than the other codes, it's fast, it continually moves and there is no offside or forward passes.
Although the game is looking more and more like basketball and soccer combined strategically. And the rules regarding contact are getting more and more 'softer'. Hence you are seeing more and more people taking dives, or pretending to be hit in the head...I suppose it was gonna happen.
American football is unbelievabley complex, used to enjoy watching it with my Yankee mates over a number of beers...great game if you understand it!
My second fav though is ice hockey, now that's a game of speed and big ass balls.
On the Brazilian front, yeh man billions poured in from the cup but I bet you only a very small percentage got any benefit from it.
