According to Adrian Wojnarowski of Yahoo! Sports, it appears the Celtics (along with the Warriors and Clippers) were strongly engaged in trade talks for Chris Paul. He later tweeted that Paul has let it be know to the Warriors and Clippers that their chances of retaining him long term would increase if they could sign Tyson Chandler. Stay tuned for more details.
UPDATE: In the full column, the deal would include Rajon Rondo and Jeff Green, but would also require a third team to sweeten the deal.
