Being a Mavs fan, I've always said who ever knocks us of deserves to win it all, in saying that, the Spurs are far from done! They still have that veteran leadership, and can still win. It's a tough tough ask, but not impossible.
OKC have definitely matured alot, and I dare say last year's playoffs has something to do with that. I honestly can't see MIA or BOS beating the Thunder in a 7-game series. I still believe the Spurs can, but I don't see the Eastern Conf winning it against them. MIA would probably knock off the Spurs, but that would depend on who's playing.
