I can already tell that the answer to this question is going to be overwhelmingly with soccer but what is your favorite sport and why? My favorite sport is American football. Despite having to watch and root for one of the most consistantly worst teams in the league, it is still a very fun game to watch. It takes a lot of athleticism and practice to pinpoint a pass, run for a first down, make a game-saving tackle, etc. Not to mention the fact that parity in the league allows any team to go from a losing record to the playoffs.
I watch nearly everything really. Tennis, sailing, soccer, rugby, formula 1, motogp. But out of the list i say Soccer.
American Football and Tennis! Everything else (especially baseball!) puts me to sleep. Unless I'm actually at the game of course.
Tennis Love playing it and love watching it, though these days dont compare to the good old days of the Sampras/Agassi and Graf/Seles rivalries.
