Being home would be the only thing. Otherwise, if you want to be in the east, you go to Miami.
I thought Boston would be the ideal East target for them, but one thing I'll say about Boston, as much as I agree with their strategy and I think they did an excellent job of stockpiling assets (mostly picks) while rebuilding and clearing cap and only missing the playoffs one year during that stretch, I think they have completely whiffled on their draft picks.
They took Olenyk high, last year got the guard from Louisville who's name is escaping me. Marcus Smart is a nice but not a game changing player. This year they reached for Brown and didn't take much else of note. They should be in a much better position considering where they drafted.
Compare that to the Lakers who didn't really do anything special in the draft, and they have a 4 man young core of Clarkson, Randle, Russell, and Ingram, (also Larry Nance) while also having more cap space than Boston.
