Paul George was expected to elevate the Sixers offense. So far, he’s been a less than sure shot.

BOSTON — Paul George is in quite the shooting slump — especially from long range.

The 76ers’ prized offseason acquisition missed all seven of his three-point attempts in a 118-114 Christmas Day victory over the Boston Celtics at TD Garden. The poor effort stretched his skid to 4 for 25 (16%) from deep over the last four games.

With his 4-of-15 skid from the field Wednesday, George also shot 29.1% in those four games against the Charlotte Hornets (Dec. 20), Cleveland Cavaliers (Saturday), San Antonio Spurs (Monday), and Celtics.

His struggles came on the heels of his best game of the season.

The nine-time All-Star forward had a season-high 33 points on 13-of-20 shooting — including 6 of 9 three-pointers — against the Hornets on Dec. 16. At the time, George talked about finally being comfortable in his role and finding his rhythm.

But he hasn’t come close to duplicating that performance.

Joel Embiid was asked if he has a message for his struggling teammate.

“Nah, I think he knows what it is, but I keep talking to him,” Embiid said. “He’s going to be great. I’m not worried about it. I think as we keep going and we start figuring out the best way to move forward, I think he’ll be way better than he’s been, more efficient, which he’s always been. Especially catch and shoot [and] shot creation.”

In 18 games, George is in the midst of his lowest scoring average (15.9 points) since he played in just eight games during the 2014-15 season. His shooting percentage (.406) and three-point percentage (.310) are the second lowest in his 15 NBA seasons.

Part of that struggle can be attributed to George’s inability to get involved while playing alongside Embiid. His best games have come when Embiid has been sidelined. On those nights, he has served as a primary ball handler, creating his own shot or settling up teammates.

Since Embiid’s return, he has mostly been a third option while the 7-foot-2 center and Tyrese Maxey have thrived in a two-man game. But Embiid didn’t play against the Cavs (26-4), and George still struggled through 4-for-12 shooting to finish with 11 points.

“I think we’ve got to move a little bit more,” George said after that loss. “I’ve got to move a little bit more. I thought tonight was a poor effort on my behalf of just moving. A lot of it was stagnant, and I’m going to see a lot of loaded-up defenses.

“So I’ve got to move a little bit better. I’ve got to run the floor a little harder. Same stuff I’ve been saying, but I’ve got to be consistent on that front to allow myself to get some easier opportunities.”

But George had good shot attempts against the Celtics (22-8). He just missed them.

The nine-time All-Star had eight points on 4-for-8 shooting while missing his three three-point attempts in the first half. He followed that by going 0-for-7 from the floor and scoring four points after intermission.

“Listen, tonight I thought his shots were awesome,” coach Nick Nurse said. “He had really good shots. So I’m encouraged by that. I think the quality of them went way up. Coming off on some of those, he’s getting 14 feet, total space and total clearance with his height, you’re thinking, ‘Those are automatic.’ And they just didn’t go in tonight. I feel good about where he was getting to and how he was getting there. I feel good about that.”

The next step is getting shots to fall.
