The logical trade to me, for both teams, is:
Celtics trade Pierce, Chris Wilcox and Keyon Dooling
Clippers trade: Butler, Mo Willimas, Bledsoe & Trey Thompkins
* Butler and Williams make the numbers work.
* Bledsoe and Thompkins make it work for us, the future.
Caron is good but he is no Paul Pierce in crunch time and Mo Williams is a rental for the Clippers, he's gone in another year.
** And yes, Pierce is worth all that to the right team, because a lineup of:
DAndre Jordan / Wilcox
Blake Griffin / Reggie Williams
Pierce / Gomes
Billups / Foye
Chris Paul / Dooling
Will win an NBA championship this year if healthy.
This being said, I would only trade Pierce if he was ok with it and if he wanted to try and win a few more titles before he was done, otherwise I'd honor the deal I made with him and use the cap space once his contract expired.
Pierce gets some home cooking and another ring or two...it;s not a bad ending...
