Jaylen Brown led Boston with 21 points and seven rebounds, but was 9 of 20 from the field and missed each of his five 3-point shots. Sam Hauser, Payton Pritchard and Anfernee Simons each tossed in 12 for the Celtics, who never led after Atlanta went in front 7-5 with 9:37 remaining in the opening quarter.
