Whats the Deal with Boston Celtics fans?

So everyone knows the Boston Celtics won yet another NBA Championship this season and this of course solidified them as one of the most recognizable "famous" sports organizations in the world. However, does anybody realize that this so called "blue collar sports town" doesn't really give a damn about their beloved Boston Celtics? Sure this season they were 12th in the NBA in attendance, but lets take a look back a few years. In 06-07, Boston was ranked 20th in the league behind New Jersey and Orlando and in 05-06, they were 18th in the league. Now tell me how this is a world famous organization that still sells many tickets by riding the coat-tails of the legendary Larry, Robert, and Kevin teams of the 80's and 90's.

My question to everybody is, why doesn't anyone realize how fair weathered these Boston Celtic fans are? They start winning a few games in 07-08 and then all of a sudden, thousands of these "die hard" Celtic fans start coming out of the parquet woodwork, and into the Garden?

Wait, there's more! In 04-05, they ranked 24th and in 03-04, they were 18th. Of course the old cliche is that if the team starts winning, the people will come. Yet how come the fans of Chicago, Cleveland, and L.A. have been pouring in the last 5 years and show their allegiance to their respected clubs. I am sick of hearing how the Boston Celtics and the L.A. Lakers are the most historic franchises in Basketball. Boston is nowhere near the level of L.A. Sure the Lakers and the Celtics have the most Championships by a long shot, but honestly the Boston Celtics fans don't give a damn about their Boston Celtics so long as the Boston Red Sox are in town (and the Patriots keep on winning). As much as I dislike the Lakers, I have to respect their fan base and the city of Los Angeles for actually showing up to see their team play whether they have a strong season, or it is a rebuilding year. Dedication and persistence people, that's all I ask.
