There are some rumors that the Celtics are frontruners for Darko Milicic. We all remember this guy as 2nd draft pick behind LeBron James, and in front of some players like D-Wade, Melo and Bosh. He is not a bust, if you ask me. He's 7'0", can defend (really well), in season 2010-2011 he had 2 blocks per game in just 24 minutes played. He can rebound, and that is probably the only thing we need from him. Only problem with Darko is his temper and work ethic, but with KG around him, that wouldn't be a problem.
I would still prefer Greg Stiemsma, but there aren't alot of elite defenders left on free agency, so please Danny Ainge - React now! Sign him, he would do great job for us.
