Free agents the Celtics might target
Caron Butler, SF
Caron Butler's name is always floated around when the Celtics are looking to add a player, and for good reason: the Mavericks forward is good. The eight-year pro ruptured his right patellar tendon Jan. 1 and has been out since. His $10 million comes off the books after this season. That's too high a price, but Butler's tenacious defense and scoring ability would fit well in Doc Rivers's system.
