According to Chris Broussard, Williams would like to be traded from ATL:
Marvin Williams continues to be an ancillary part of Atlanta's offense and sources say he would like a trade.
Williams is averaging just 9.6 points per game this season and would like to find a situation where his usage increases.

What are the thoughts on this deal?
ATL Receives: Ray Allen $10,000,000
BOS Receives: Marvin Williams: $7,500,000
Eric Dampier: $713,666
I'd prefer to get Jason Collins in this deal but he's not available in the trade machine for ESPN. I'm sure someone can figure out how this works.
Why Boston Does it: I think Marvin Williams is a suitable Jeff Green Replacement on a reasonable contract. We can mitigate Ray's exit by moving Pietrus into the starting 2 role. I also believe he still has some untapped potential.
Jason Collins or Dampier would give us some valuable interior depth. Collins is an excellent interior defender and would be key if we saw ORL in the playoffs.
Dampier would be a throw in if they wouldn't offer Collins for interior deth without the same returns.
Why ATL does it: I think Allen would be great for them. He would provide some much needed veteran leadership and his production could steal them a playoff series. Hinrich could spell him off the bench to compensate for his defense.
ATL also gets out of the Williams contact for the following two seasons.
I think Marvin Williams is a nice risk for the Celtics and is still only 24 years old.
