The Celtics depth chart is a pretty crowded place as training camp begins, especially for big men. With Al Horford projected to start at center and Jayson Tatum playing plenty of some stretch four, it's going to be hard for the likes of Aron Baynes and Daniel Theis to get solid minutes at center on a nightly basis.

That reality means rookie Robert Williams isn't going to see the NBA floor in a meaningful situation anytime soon, in all likelihood. The Celtics simply won't have a need for the athletic 20-year-old, barring injury. A source confirmed to BostonSportsJournal.com that the team plans on keeping Williams for extended stretches with the Maine Red Claws once the season begins, but that plan is on hold for the time being. Instead, the focus on getting Williams healthy after a battle with knee tendinitis that has stretched throughout his college career.
