I don't really understand the problem? are these small market teams? I mean, clevland is, but they have lebron, so everyone watches them. T.O. is a big market when you consider they rep all of Canada, not just the ~5 million people in the city. Charlotte and milwaukee are small market, but are Miami, Atlanta and Orlando "small market teams" now?
I agree that the NBA would greatly benefit from a NY team in the playoffs, but these match ups don't seem all that small/boring to me. (aisde from boston and milwaukee)
