“We were getting decent looks, but we just weren’t making them,” Porzingis said. “And when you’re not making them, not that our energy was lacking, but it’s just not the same hype. And honestly, they were taking and making some tough shots, and they were also making the open ones.”

The Celtics also saw their worst shooting percentage (39.2 percent) from the field in a game this season, connecting on 38-of-97 attempts.

Meanwhile, Chicago is coming off one of their best defensive performances thus far. They had 56 rebounds and forward Zach LaVine led the offense with a season-high 36 points.

“They played physical,” Jaylen Brown said. “They hit shots. They guarded well. If a team’s hitting shots and guarding well, anything can happen on any given night.”

Sam Hauser is questionable to play with lower back spasms.
