Yahoo! Sports Adrian Wojnarowski references the Celtics in his trade rumors article:
The Hornets will likely be in pursuit of New Jersey Nets forward Troy Murphy(notes) once the Nets reach a buyout agreement with him after the trade deadline. Nets coach Avery Johnson made clear he didn’t want Murphy after the three-team trade that brought him from the Indiana Pacers. Trade talks have gone nowhere for Murphy, who has an expiring contract. Nets GM Billy King will ultimately work a buyout to free Murphy to sign elsewhere.
Richard Hamilton(notes) will have to be willing to give back a significant portion of the two years, $25 million owed him to get a buyout on his contract. Sources said the Celtics still remain intrigued with Hamilton as a scorer off the bench.
While we've heard the speculation regarding Rip Hamilton before, this is the first time I've read Troy Murphy and the Celtics in the same paragraph.
Murphy is a big body who can rebound (8.5 career average) and shoot from the perimeter. I can't imagine the Celtics bring him in, unless Jermaine O'Neal and/or Shaq couldn't go the rest of the season.
