According to reports, the Boston Celtics have some interest, and it makes plenty of sense. Whether they view him as a star instantly when he returns from his injury, or someone they can pair with Jayson Tatum and Jaylen Brown in certain sets, there's reason to believe that Lillard would be a great fit.
