Rajon Rondo was there in the flesh, and his teammates showed up in force.
Behind contributions from all over, from their captain to a forward that joined the team midseason from China, the Celtics shot the lights out at TD Garden and thoroughly routed Atlanta, 118-107, on Friday night.
Boston won its second straight game overall as Rondo, its All-Star point guard, returned to the bench for the first time since his season ended with a knee injury.
The 118 points tied the Celtics’ season high; they scored that many in a triple-overtime win against Denver on Feb. 10.
Overall, the Celtics shot 53 percent (45 of 83) and made 11 of 23 shots from beyond the arc.
The Celtics received a huge boost from Jeff Green, who scored a game-high 27 points two days after making a game-winning layup in Cleveland.
Green made 11 of 20 shots and buried a dagger 3-pointer with 1:56 left in the fourth.
Paul Pierce recorded his third triple-double of the season, with 20 points, 10 assists, and 10 rebounds, and then the bench came up huge, namely Shavlik Randolph and Jason Terry.
Terry (24 points) hit five 3-pointers, including a key trey with 5:49 left in the fourth quarter that put the Celtics up by 11.
Randolph, meanwhile, provided a huge spark, scoring 9 points and grabbing a career-high-tying 13 rebounds in 22 minutes.
The Celtics used a 27-10 run in the second quarter to turn the game around. It was in that frame that Terry scored 14 points and hit four 3-pointers.
Mike Scott led Atlanta with 19 points. Josh Smith added 18 points and Jeff Teague had 17 and seven assists.
