Every other NBA team has had dancers for awhile with the Celtics as the lone exception. There are even NBA All-Star Dancers now from each team, there is a bit of pressure from Wyc from the NBA Entertainment machine as there had been before the C's finally relented. It might be a quaint notion that the C's are "different" from every other NBA franchise, but one year contending after 20 years since #16 doesn't put them in some elite status. The NBA orchestrates most of what goes on for entertainment for the league as a whole, the C's didn't simply add them because they were an awful team and only until they were in contention again, that simply made the timing easier. Fans who want to complain about the practice are years behind in their efforts as if you were an NBA fan in any one of the other 29 cities you would have been dealing with this for years at games.
If one wants to moralize over the whole issue of dancers at NBA games, not simply dancers at Celtics games, than his or her issue is with the league, and it is a legitimate opinion to wish the NBA's teams did not have dancers. But it is naive to think the Celts can just decide unilaterally based on moral objections to drop them now, when every other team has had them for years and the C's were the last team to add them. Every point made here about the distraction, interruption of the flow, etc. exists in every single NBA arena, and in many cases, to a much greater extreme in Boston. As much as Celts fans like to hold themselves above all other fans, the Celtics are an NBA franchise that operates under the umbrella of the league as a whole, just like every other team. Start a campaign at the league office to rid the NBA of dancers (or T-shirt guns, or mascots, or loud music) if you want, but to single out Boston on this issue is missing the point.
