“We had something in our hands that we lost,” Pacers coach Rick Carlisle said. “It’s disappointing. We did a lot of good things and we have to continue to clean up the things that we need to clean up.”

Offensively, Tyrese Haliburton’s pick-and-roll schemes and Pascal Siakam’s low-post spin cycles haven’t matched last year’s scoring, but their connection is still a dangerous threat inside and out.

At the other end of the court, the Pacers — who had the seventh-worst defensive rating last year — haven’t figured it out in their 1-3 start, with glaring perimeter and rebounding issues that have gone unresolved.

On the Celtics’ side, their title defense (while dealing with Kristaps Porzingis’ absence) has been nearly perfect. Payton Pritchard went off on the Bucks at TD Garden on Monday, capping a memorable night with 28 points in 28 minutes — including eight 3-pointers — in a 119-108 victory.

“Payton is a killer,” Jaylen Brown said. “He’s always looking to put pressure on a defense. If you don’t put pressure on him and you don’t protect him, he’ll turn you on.”

As the Celtics land in Indianapolis to begin a four-game road trip, they hope Pritchard’s hot shooting and energy remain.

Sam Houser has been upgraded to probable to play Wednesday after being sidelined with lower back pain.

I thought we did a good job of that .”
