Atlanta would almost certainly want a young, talented true center or a young, talented point guard who can run their offense. Those are their two major needs if they are parting with Josh Smith.
So unless you want to give up Rondo, I don't see how we could acquire Josh Smith.
Just for kicks, suppose we do this and resign our guys. Entire FA / amnesty focus goes toward center spot, which isn't much of a change unless you think we're getting much our of O'Neal.
Kevin Garnett, Jermaine O'Neal
for
Joe Johnson, Josh Smith
Lineup:
Rondo / West
Johnson / Allen
Pierce / Green
Smith / Baby
?? / Baby
Why for BOS: Start a new era overnight with Rondo, Johnson, Smith, Green. Ray Allen becomes our 6th man, Johnson & Green allow for Pierce & Allen to take nights off and limit their minutes this year. Josh Smith reasonable replacement for Garnett considering age and health. Lots of scorers around Rondo. Smith clearly wants to play here, and Johnson would be a homecoming story.
Why for ATL: They would kill to unload the Johnson contract entirely and could be a major FA player with only Horford on a long term deal.
