Philly (currently - who's winning or losing can make a big difference in the rankings):
1) Eagles - probably because they've done great the last 3-4 years. Not being a fan of the team, it gets on your nerves during the season
2) Phillies - addition of Thome & Wagner, resurgence of Burrell, high expectations for the team, new ballpark.
3) Flyers - made a run in the playoffs
4) 76ers - they were big when they made the finals in 2001, but it's been downhill since then. If you did this list in 2001, the 76ers would be #2.
