The Boston Celtics have been attempting to trade away David Lee and his $15.5 million expiring contract.

Lee, however, has not been generating any interest on the trade market. The Celtics are only likely to trade Lee as salary cap filler in a blockbuster deal.

Lee fell out of Brad Stevens' rotation earlier in the season.

“David Lee was tough for Golden State to move all of last year,” said a source. “And it finally came down to him being moved for Gerald Wallace. David Lee has no value. It’s his contract. David Lee’s value comes in if they get one of these big name players.”
