Theis wasn’t a huge factor in the Celtics rotation this year, but he was effective. He was a hybrid of the two other centers Boston has on the roster, Aron Baynes and Greg Monroe. Theis wasn’t as good defensively as Baynes, but he did the stretch the floor and grab offensive rebounds. He didn’t have a dominant post-game like Monroe, but he could block shots and play good position defense.
Even more, he was a young player getting ready for his first appearance in the playoffs. If Theis is a part of this current team’s plan, the experience would have been more helpful than anything else. Now, the Boston Celtics are locked in to the centers they have now. Unless, of course, the injury bug runs its course again.
