Latest NBA trade buzz: What we've been hearing

The Philadelphia 76ers have been one of the most proactive teams in trade talks over the last two weeks, but indications around the league are that the struggling Sixers may be pulling back before the deadline.

Sources say Philadelphia -- which has dangled Samuel Dalembert, AndreIguodala and Elton Brand in various deals -- has been less involved in trade discussions over the last 48 hours. According to one source, Philadelphia¹s chances of making a deal before Thursday's deadline are "50-50" and that the team will not hold a fire sale for its available talent.

The New York Knicks are finalizing a deal to acquire Houston Rockets forward Tracy McGrady, an NBA source told SI.com.

The framework of the deal involves sending McGrady to New York for forward Jared Jeffries, guard Larry Hughes and forward Jordan Hill. The Knicks and Rockets have agreed to swap 2011 first round picks and the Knicks will send the Rockets their first round pick in 2012.

The only outstanding issues involve protection for the draft picks, meaning Houston would be given the picks only if they fell within a certain range in the draft. If the picks are taken in the protected range, the Rockets would not get them until a year after they were drafted.

The deal could be completed as early as tomorrow.

League sources told SI.com on Tuesday that newly acquired forward Drew Gooden is in the process of negotiating a buyout with the Wizards.

Gooden, who was part of the seven-player deal that sent Caron Butler and Brendan Haywood to Dallas, is not interested in playing for the Wizards, sources say.

An NBA source says that if Gooden is bought out, he will wait the league-mandated 30 days and return to the Mavericks.

The Milwaukee Bucks have been active in their pursuit of a power forward to pair next to center Andrew Bogut, multiple league sources told SI.com on Tuesday. Because the Bucks do not project to be under the cap this summer -- as opposed to 2011, when the contracts of Michael Redd ($18.3 million) and Dan Gadzuric ($7.2 million) come off the books -- Milwaukee has expressed willingness to take on players with contracts that run through next season.

One option for the Bucks, sources say, is Indiana forward Troy Murphy, who has been made available by the cost-cutting Pacers. Murphy is due $12 million next season and has been linked to the Cleveland Cavaliers. In 42 games this season Murphy is averaging 14.0 points and 9.9 rebounds while connecting on 48.7 percent of his field goals, including 38.6 percent of his three point attempts.
