Doc Rivers saluted the impact and influence of Joel Embiid after his stellar showing drove the Philadelphia 76ers to a 122-110 win over the Boston Celtics.

Two days on from scoring 42 points in seeing off the Celtics, Embiid was on it once more against the same opposition, plundering 38 points and grabbing 11 rebounds.

With Tobias Harris weighing in with 23 points from 10-of-12 shooting, and Ben Simmons coming on strong with 11 of his 15 points in the fourth quarter, Philadelphia had an irresistible combination.

"We're just growing, you can see it," coach Rivers told a post-game news conference.

"When you look at Joel's numbers - 11 from 15 - he didn't force it a lot, made some great plays out. 

"He let it comes to him. Down the stretch when they were starting to trap him, instead of winning the ball he actually was trying to get the ball to move the ball.

"It says so many things to your teammates. Then when Ben got it going it was Joel who was wanting to call the pick and rolls to get him going more.

"I like how the chemistry of this team grows each night. During COVID it's hard to try to get chemistry and you can see it growing."

Rivers applauded the "quick decisions" that Harris made in the game, declaring that on his best form he is an "unbelievable" talent.

"He's a train going downhill," Rivers said. "He's got a beautiful shot. I love how he's playing. I love what confidence he's playing with."

Even when Harris takes to showboating, Rivers is prepared to stomach it.

"It's going to happen and that's fine. He is talented enough to do it, I just don't think he's efficient when he does it."

Rivers said Simmons' impact in the closing quarter was "awesome". As well as his priceless points, Simmons also had 11 assists.

"He's doing so many things for this team. His winning formula is amazing," Rivers said. "Ben does a lot. He can't focus on one thing like focusing on just scoring, he's too good for that for me.

"It would be a waste if that's all we focused on with him.

"What I did like is he went downhill more tonight and finished at the basket. That's what he has to do and that's what we're working on."
