The Celtics acquired Jeff Green because of his youth, versatility, and the ability to re-sign him this summer. Green will give the Celtics every chance to bring him back, according to his agent, David Falk. Green is a restricted free agent next season, meaning, under the current collective bargaining agreement, the Celtics can match any offer made to the fourth-year swingman. They didn't have such rights with Kendrick Perkins, who was an unrestricted free agent. After a month in Boston, Green is getting accustomed to the atmosphere and appears comfortable enough to make a long-term commitment.
