I don't mind the PA guy for the most part. Kinda ticks me off when he yells "KG!" after Garnett scores...I wish he would refer to him by his full name...weird, but we all have little, odd things that tick us off.
The game has evolved both on and off the court, & with that, even changes have to occur with one of the league's most storied and traditional franchises. From the Fab 5 bringing baggy shorts mainstream, to headbands, arm sleeves, wearing sweat bands on legs, forearms rather than elbows, equipment is more about fashion in a sense than actually using it for its purpose (example, a headband absorbing sweat)...it's just always going to be this way. I wouldn't mind if the Celtics stayed totally traditional...no dancers, no light shows or extreme jumbotron presentations...it doesn't affect me one way or the other, but they're trying to appeal to what the league believes the modern fanbase is composed of & you can't fault them for it. They're trying to present a product they believe the majority of basketball fans will go for.
