The Celtics made very few external additions this offseason. First-round rookie Baylor Scheierman, the 30th overall pick, was the most significant.

He might struggle to crack the regular rotation as an NBA freshman, but that has more to do with this roster’s quality than it does his skillset and readiness.

He’ll get some run, though, and when he does he should be a hand-in-glove fit with this group. His perimeter shot is potent, but he could function as more than a three-point specialist. He keeps active on the glass and has enough handles and vision to grab rebounds and get out in the open court. This machine wouldn’t have to slow down to accommodate him, in other words.
