someone needs to catch up on their sports history... The title of "Greatest Sports Franchise" ever belongs to the Yankees. 26 World Titles.. which is 10 more then the Celtics. The Celitcs aren't even 2nd in the list of greatest sports franchises ever. The Montreal Canadians are second with 24 Stanley Cups. Please... the celtics are "have beens." There record is about to be smashed by the Lakers.
