Robert Williams III might be within the Boston Celtics' price range as a free agent option next summer.
Change has been plentiful in Boston this summer. The Celtics saw several key contributors leave town one way or another. They specifically lost much of their depth at the center spot, with Kristaps Porzingis being traded to the Atlanta Hawks, then Luke Kornet and Al Horford leaving in free agency.
This season serves as an audition for players like Neemias Queta, Luka Garza, and Chris Boucher.
