You gotta think if Chicago signs two max free agents they will move to the top. Lebron with Rose and Noah makes them a contender.
Orlando should have their same team. (Vince for Arenas maybe?)
Boston will have their same team but are getting old (could possibly lose Ray Allen)
Miami has the money to sign three max free agents (Wade, Bosh, and ?) would make them a favorite.
If the Knicks can sign a couple of free agents they'll be in the playoffs. (Johnson, Stoudamire, David Lee would be a good combination to make the playoffs)
The Nets have the money, a decent point guard in Harris (who didn't play much at the beginning of the year) and a good big man in Lopez. If they are able to sign a free agent or two (perhaps Boozer) they'll be in the playoffs as well
Not to mention Milwaukee has a young team that is on the rise (remember Bogut didn't play in the playoffs).
Then theres several other teams who could challenge for the last two or three spots. Washington with Arenas and Wall. Philadelphia with Turner. Atlanta still has a good team but not sure how they'll do if they lose Johnson.
The only teams I don't see making it are Cavs (if they lose Lebron

I don't think you can make the playoffs with a .500 record in the east next year so where do you see the Pacers finishing? Are we looking at a 12th place finish this year. I think it's obvious Bird definitely has to make more moves if we don't want to be in the lottery again next year. We can't go into next year with Ford as our PG which makes acquiring Collison, Flynn, or Lawson that much more important!
