Right now I see Rondo,Bass,MP3,JGreen, and the rookies as worthwhile assets. Signing Bass,MP3 and JG to reasonable 2/3 year contracts would be a good thing and not totally destroy our cap space and flexibility.
All others, including the Big 3 I would move at the trade deadline for any young players with potential or picks I could get. They are either too old, or minimum vets not worth keeping long term.
Get what you can at the deadline, see what happens in the draft and go from there!
