I wish there was some way the Celtics could acquire restricted free agent Jawad Williams from Cleveland. He fits what I think the Celtics need: a back-up small forward who can also play some minutes at power forward (perhaps as a stretch four in a small lineup). He's an athletic defender (but not a lockdown defender) whose offense isn't great but is good enough that he can't be left completely unguarded. On the other hand, he's a 27-year-old who has played only 64 regular season NBA games over two seasons, who was undrafted and spent time playing overseas, and who has been previously released by the Cavs.
It's unlikely because he's a hometown boy that Cleveland likes and because he is a restricted free agent. On the other hand, a willingness to try Williams as a starter might make Moon more expendable.
