The Celtics Get:
Joe Johnson, SG, Atlanta Hawks
Josh Smith, PF, Atlanta Hawks,
Andre Iguodala, SF, Philadelphia 76ers
Why Would Boston Do This?
Boston starts the rebuilding process by acquiring three All-Stars. Not Bad. They would like to allow Paul Pierce to finish his career in Boston, but its a sacrifice that may need to happen to acquire Andre Iguodala, an elite defender who is seven years younger than Pierce. They also get an incredible athlete and human highlight machine in Josh Smith who would excel with Rajon Rondo. Joe Johnson would also do well surrounded by a cast like this. Financially, Boston would be taking on a lot of money, but they would actually be paying less for Johnson, Smith and Iguodala then they did Garnett, Pierce and Allen this year.
The Hawks Get:
Kevin Garnett, PF, Boston Celtics
Evan Turner, SG, Philadelphia 76ers
First-Round Pick from Boston (Originally Clippers 1st Round Pick)
Why Would Atlanta Do This?
Atlanta would probably would like to get out of Joe Johnson's contract. The chances of him keeping his level of play where it is currently over the next five years (and $90 million dollars) seems slim. They believe they have a shot to land Dwight Howard, should he hit free agency, and shedding both Joe Johnson and Josh Smith's contracts would give them bountiful cap space.
In addition, Kevin Garnett's $21.2 million comes off the books at the end of this year. They would also acquire young and talented SG Evan Turner to replace Joe Johnson. The first-round pick they received certainly won't be lottery pick, but it would replace the first rounder that Atlanta does not have in 2012.
Paul Pierce, SF, Boston Celtics
Ray Allen, SG, Boston Celtics
Why Would Philadelphia Do This?
Philadelphia has played well this year by all accounts, but they are a young team that lacks a true "superstar." Paul Pierce is an upgrade offensively over Andre Iguodala and almost as good defensively. He, along with Ray Allen, would provide a veteran presence on a very talented 76er's team. Considering how badly the Philadelphia 76ers were recently beaten by the Miami Heat, it wouldn't be surprising to see a change coming.
