With the Pacers' self-destruction, I can really only see Miami coming out of the East. I really doubt any eastern team will be able to beat them in a seven game series.
On the flip side, I could see at least five teams from the West making it to the finals. The Spurs and Thunder are givens. Clippers are also really good and will be a nightmare for the Spurs if they end up playing in the WCF. The Warriors and Rockets could also be trouble if they get hot. And Portland is there, too. I dunno.
I'll say Heat/Clippers in the finals with the Heat winning in six.
