I think Marcin Gortat would solve a lot of problems for the Celtics. Can play PF,and C. Good defender,rebounder and decent offensively. Plus, his contract is very reasonable this year and the next.
Would a package of Bass, Melo, Wilcox, and first rounder be enough? I wouldn't part with Bradley or Sullinger. What do you think the Suns would want for him?
