We could sign Donte Greene and Chris Andersen
I think Danny Ainge should sign those two players anyway.
Use Darko's vacated spot for Chris Andersen and waive Kris Joseph to sign Donte Greene. The team needs another big wing with legitimate size who can defend his position. Greene offers that. A good third string combo forward who can also play some two if necessary. Nice utility player. Chris Andersen would become the team's main backup center. Jason Collins would remain as third string for when playing against a more physically imposing opponent. Wilcox and Sully would duke it out for the power forward minutes behind Bass.
