Garnett has promised the Celtics a decision by Saturday. Then Ainge can start the process of reconfiguring the team and allotting the vast millions that could be at his disposal. Will Allen stay? What about Brandon Bass and Mickael Pietrus? And then there's Jeff Green, who pretty much has to be signed lest the Perkins trade go down as Ainge's worst decision ever (some would say it already is regardless of what happens to Green).
