Simmons, the No. 1 pick in the 2016 draft who sat out all of a year ago with an injury, was heckled by the Boston crowd with chants of "Not a rookie!"
With much of the attention focused on Philadelphia young guns Simmons and Joel Embiid, Boston's youth movement of Tatum and Rozier led the way.
The trio of Terry Rozier, Jayson Tatum and Al Horford combined for 83 points as the host Boston Celtics beat the Philadelphia 76ers 117-101 in Game 1 of their Eastern Conference semifinal series Monday night. He, JJ Redick (20 points) and Ben Simmons (18 points) were the only 76ers to score more than 12, but Simmons had seven of the team's 12 turnovers and struggled to find a rhythm as a facilitator and creator.
After a six-day layoff, the Sixers were back in action for Game 1 of their Eastern Conference Semifinals series against the Celtics.
It was the Terry Rozier game for the Celtics as the guard did everything right in all the right ways for Boston. He had 10 points and six assists in the first quarter and was 7 for 9 from 3-point range overall, overshadowing the lottery picks accumulated by Philadelphia during The Process.

He added that Kim had promised to invite United States and South Korean experts and journalists to watch the closure, in the interests of transparency.
Coach Steve Kerr listed the two-time MVP as probable Monday with the idea that he's a go to play as long as no issues arise with Curry's sprained left knee. Boston led 87-70 in the final minute of the third quarter when Philadelphia scored nine straight points to make it a nine-point game.
Philadelphia coach Brett Brown added, "I thought this was one of our poorer defensive games".
"I'm not the decision-maker on that", Stevens said.
The first half of the contest showed just how rusty the Sixers were with six days off from Game 5 last Tuesday. Whiteside, who missed extended periods of time with knee and hip injuries this season, publicly complained about his role after a loss in Game 3, a similar reaction to his expletive-filled rant at the end of March that earned him a fine from the team. Legendary Celtics center Bill Russell attended the game and sat courtside. Smart missed his first five shots. The "L-A" were in bold, a nod to the longtime rivalry with the Lakers.
