With news surfacing that Darko Milicic could be on his way out, the Celtics have found themselves in a good position to sign free agent forward Kenyon Martin.
Martin drew interest from the Celtics during the offseason but the Celtics ultimately decided to sign Milicic, Collins and to re-sign Wilcox instead. Now with a potential roster spot opening, Martin would be the best option for Boston.
Marcin Gortat has reportedly been on the Celtics radar but can only be acquired via trade. Although Gortat is a better player than Martin, he's going to cost Boston a lot. The only way I see Phoenix agreeing to a deal is if the Celtics are willing to include Avery Bradley, who is someone the Celtics are going to need this year, especially against Miami.
Martin would have no problems fitting in with Boston. His scrappy play and shot blocking ability are qualities that would only make the Celtics' frontline better defensively.
