The Celtics, Bulls and Clippers are expected to aggressively pursue Dwight Howard, who has requested a trade from the Magic.

Orlando has given Howard's agent Dan Fegan permission to speak to the Nets, Mavericks and Lakers about Howard.

Howard is eligible to become a free agent in 2012 and while the Magic haven't given up on retaining him, they do not want to lose him without compensation in return.

According to Brian Schmitz of the Orlando Sentinel, the Magic are in trade talks with teams beyond his primary choices as one would expect.
