well,I guess the only good thing to say in all of this is that a Heat "dynasty" isn't really a given even if they win the finals this year...The East(and the west) are in transition this year..
The bulls are a another shotmaker away from being championship level, you have another 2 superstars in NYC who with the right roleplayers(and coach) can challenge Miami. and Boston is still around...and in the west, you have teams like the Thunder, and lakers who will still be competitive
