The Clippers will have interest in Paul Pierce as a free agent if he's bought out by the Celtics, a source told the Los Angeles Times.
That seems rather obvious. If Pierce is bought out, he'll draw a ton of interest in free agency. However, the Celtics would prefer to trade Pierce if they're going to move on, and they'll exhaust every avenue to get a return for Pierce. We can't imagine a scenario where the Celtics simply let him walk and pay him to do so knowing there's interest in his services around the league.

Marcus Landry will play for the Lakers in summer league, according to his agent.
