Probably about 5 teams who could take it out over the next few years.
Jazz are a few savvy trades away from a championship; kirelinko and okur for tayshaun? add a diop type and a breakout year from almond or brewer and they'd be legit contenders.
New Orleans trade peja for an all round 2 gaurd - maybe a poor mans Roy plus a bell, battier, posey type and a bit more of a bench.
San Antoinio's big 3 + Bowen still have 2/3 good years. Thier role players didn't hit treys, if they did they could've easily went back to back. Expect some quality free agent signings with more athleticism.
With Bynum, Farmer, Vujacic, Ariza, Turiaf and Walton another year under thier belt they will be deadly for years to come. With Bynum around Gasol will slide into his role as a finesse player and not be relied on to bang. Bynum will able to get a seal at the block as opposed to a foot out which totally distorts the triangle and ruins the angles and spacing. Possibly trade Odom for Tayshaun? If not Odom will be far mor comfortable as the 4th option/X-factor, the 'if he's playing we'll they're unbeatble' type. If they can add defensive small forward or if Vujacic or Ariza learn how to deal with a pick that'll help.
There are several teams who could concievably contend based on offseason moves.
Philly could be up there if they get Brand and Posey/Battier/Bowen clone (every team needs one). Could compete with lakers with one of the best benches aswell Williams, Green and Young all possible future all stars with hopefully something from Carney.
Miami? Wade, Rose, Brand, Haslem + breakout year from Banks, Cook, Wright or Brown.
Portland? Depending on if whether or not Oden is good as advertised.
