Do yourself a favor and check out their main forum and general NBA forum. More than half of their board right now are threads about how KG is a scumbag for those shoes, ESPN's Celtics complex, etc etc. Some of their fans say that they don't care about the Celtics, yet 75% of their General NBA forum is cluttered with posts that link readers to every different Celtics fan blog on the internet with stories about what Kendrick Perkins said, what Doc said, what kind of tissue our strength coach used to blow his nose on, etc etc.
I got no problem to admit I hate the Lakers. Whenever we are on the verge of playing them, I really start reading up on them, reading their forums, etc. I do think that Laker fans hate us more than we hate the Lakers. I think that has to do with the fact that the Celts are kinda the third team here, and the general Boston sports fan saves up most of his hate for the Yankees and Jets/Colts. So the Lakers kind of get put on the backburner. But to the diehards like myself, and the old timers. It's personal. And from what i've been reading on the Lakers forums, I'd love to stick it to those jesters on Sunday. Maybe some of them when they go to sleep that night will have fear of leprachauns crawling from under their bed and attacking them.
