I say keep KG and Pierce if you can swing a deal to get a big and a guy that can create his own offense. Make Green, Bradley, Sullinger, Crawford, Bass, Lee and our draft pick available. We probably won't be able to get anything for KG and PP that is worth it, so keep them. They are still good players and I believe that they would be better suited as role players.
Nope.
KG is retiring, and they should make a trade&retire with Detroit for Charlie V+Singler+ a future first rounder (or to Orlando for Turkoglu+pick). KG files retirement papers and the Pistons save some money
Green, Bradley and Sully's trade value is only going to rise. The Celtics won't need to tank because without KG they're bad, and they could keep Rondo and Sully off the court until they're 100% healthy, maybe after ASG.
The Captain... I don't know. They could trade him for something valuable and sign him as a FA next summer, or they could retool his contract. Even with him on the team, they can be a bad team, as he's old and needs lots of rest.
Trade Terry if you can, trade Lee/Bass if you're getting good offers. Be a terrible team next season and try to get back for the 2014-2015 with Rondo/Bradley/Green/Sully, the draft picks and maybe Fab Melo, T-Will and whoever Danny can get.
Don't trade Rondo, he'll come back better than ever.
