Joe Johnson scored 30 points while Josh Smith had 19 points and 12 rebounds for the Hawks, who are in line to be the No. 4 seed in the Eastern Conference, with Celtics No. 5.
This game, however, looked nothing like a playoff game early. Both teams shot over 50 percent and Atlanta took a 58-49 halftime lead while Boston guard Avery Bradley scored 17 of his career-high 28 points.
Boston left Rajon Rondo, Ray Allen and Mickael Pietrus at home with injuries, and perennial All-Stars Kevin Garnett and Paul Pierce were rested, having played 11 games in 15 days.
