Well, let's see. During football season, nothing short of a fire will get me out of my apartment. People who know me know not to bother me unless it's literally a life or death situation. I will also watch the occasional CFL or Arena League game. My teams are the Saints, and of course my alma mater, the UL Lafayette Ragin' Cajuns.
I follow hockey throughout the season, but I primarily watch it during the playoffs. Television, by the way, does not do hockey justice. Anyone who tells me that they don't like hockey but have never been to an NHL game has a worthless opinion as far as I'm concerned. My team is the San Jose Sharks.
Baseball is my favorite sport to just watch and relax. In fact, I'm watching the Royals and the Mariners as I'm writing this. Baseball is also a great sport to see in person. If I had to pick a team, it would be the Minnesota Twins. I also love to listen to my alma mater's baseball games on the radio.
I can take or leave basketball. I follow the NBA mainly to keep up with the Hornets, but I don't really watch it. I do, however, like college basketball, especially the NCAA tournament.
As for NASCAR, I kind of follow what's going on, but I don't really get into it. I really don't know if Bodell Jenks, Bodell Jenks Jr., or Bodell Jenks III (see The Simpsons) punched out his teammate in an argument over who gets to have a Powerade sticker on their car. I did have a chance to go to a NASCAR race once. Boy, those people REALLY get into it.
Beyond those sports, I'm a Tiger Woods fan, but not really a golf fan per se, so as far as I'm concerned, every tournament from now until he gets back doesn't really count. I will also watch tennis near the end of a major, World Cup soccer, the Olympics, the Tour de France, the occasional IRL race, and horse racing during the triple crown races.
I also take most of my vacations to see sporting events. In my life, I have been to 5 NHL arenas, 5 MLB stadiums, 3 NBA arenas, 2 NFL stadiums, and 1 NASCAR track.
In summary, there is not a day in my life that goes by without exposure to sports in some way, shape, or form.
Oh, and no, I don't play any sports.
