The Celtics’ role players stepped up in their 121-108 victory over the Heat. After Tyler Herro came off the bench and dominated Game 4 for Miami, it was Boston’s role players who got the job done in Game 5.

Despite being an undersized center, Daniel Theis was dominant in the paint. He finished with a game-high 13 rebounds and three blocks. He also had 15 points.

Marcus Smart also played well and did a bit of everything for the Celtics. He finished with 12 points, eight assists, eight rebounds and four steals.

Gordon Hayward added 10 points off the bench as he looks to get into rhythm after returning from an ankle injury, and Enes Kanter had eight points off the bench as he got some rare playing time.

Boston will need their role players to step up once again in Game 6, which will be Sunday night. The Celtics are looking to accomplish what the Nuggets have already done twice this postseason, and advance after trailing 3-1 in a series.
