I want a backup PG and a starting C.
Gortat has been mentioned but I am not wild about about giving him a big contract. I think he has started to decline already and I am worried how well he'll hold up through a 4 year deal. Not much quality beyond Gortat though. Okafor looks the next best option. Missed last season with injury but he was pretty good the year before. Okafor could be a good option on a one year deal. Help Boston get to next summer when more talented centers are available. Only a limited pool of centers available this summer. Next best options - Chris Andersen, Spencer Hawes, Jason Smith.
The backup PG. I want an actual PG. Farmar. Ridnour. Sessions. Udrih. Nate Robinson might be worth a 2nd chance. Nate might fare better with Coach Stevens than he did with Doc. Yeah I could sell myself on Nate being 1st option here. His scoring ability, shooting ability and can drive to the basket. I would love to have a backup PG who can get into the paint off the dribble and make jump-shots (like JJ Barea).

No interest in keeping Babbs or Chris Johnson. Waive them.
Bradley depends on the price tag. If Bradley walks, then the team would need a SG as well. A minimum contract SG. Probably a shooter. Like Morrow or Meeks or someone like that.
----------------------------------------------------
PG - Rajon Rondo, (free agent), Pressey
SG - Marcus Smart, Avery Bradley or (free agent), James Young
SF - Jeff Green, Gerald Wallace
PF - Jared Sullinger, Kelly Olynyk, Brandon Bass
C - (free agent), Victor Faverani, Joel Anthony
One roster spot left over. Depends on whether Ainge can trade Bass or not. If Ainge can trade Bass, then a combo forward type who can defend both SF + PF and bring speed to the table would be preferable. If Bass stays, maybe another shooter (SG/SF) should be priority. Even a small one (SG/PG) like Fredette since James Young is big enough to play some SF minutes if necessary.
