Who on the Celts isn't a playmaker if KO is?
Not playmakers:
Avery Bradley
Brandon Bass
Tyler Zeller
Jae Crowder
Jonas Jerebko
Gigi Datome
Sullinger has shown playmaking ability, but Olynyk is a better ball-handler and passer than he is.
Smart's a playmaker, but he has room to grow in that area.
IT, Turner, and Pressey are probably the best playmakers on the team.
Gerald Wallace is a good passer and has good court vision, but of course he rarely plays anymore and doesn't have the offensive ability to pressure the defense at all.
Brad Stevens's system requires having multiple playmakers on the floor at all times, which is why Evan Turner got so much playing time despite being a mediocre defender and a very inefficient scorer.
