Firstly, Phoenix, which could be done on Dec. 15th:
Sarver is one cheap owner, and the Suns are looking to the future, as the present is somewhat bleak.
Sarver will want two of Bradley/Sully/Melo, as they are all cheap (on rookie deals) and will probably want an expiring and picks.
Since this has to be done sooner, rather than later, Courtney Lee will be the sacrificial lamb as his contract is the first of Green/Bass/Lee that can be traded.
Lee's 4 year $5mil may be palatable to Sarver, but I can see him demanding a third team be involved to get him an expiring.
Also, everyone assumes that it is Bradley who will be demanded by Sarver. I'm not so sure that Bradley's trade value due to the question marks about his health is as high around the league as it is on this blog.
I can see Sarver taking Sully/Melo plus Lee/expiring from 3rd team and picks.
Now Atlanta:
Aside from Josh Smith and Horford, Atlanta is pretty weak as far as starting "talent" goes, especially at the 3/4. Enter Jeff Green and Brandon Bass. Both have been starters for talented teams and both are definitely an upgrade over what Atlanta has (or doesn't have) right now, aside from Josh Smith.
Smith will most likely be leaving at year's end, and they could lose him for nothing.
If Atlanta is building around Horford, they need to surround him with some talent. Both Green and Bass are close to Horford's age and fill a need. So:
On January 15th, Green and Bass for Josh Smith.
Add Kmart and Pietrus, and we are good to go.
Gortat/Wilcox/Collins
KG/JSmith/Kmart
Paul Pierce/Pietrus/Joseph
Bradley/Jet
Rondo/Barbosa
