Irving has been sidelined since mid-November with a shoulder injury.
Despite his lengthy absence, fans have voted him into an Eastern Conference backcourt starting spot in early voting for next month's NBA All-Star Game.
In the 11 games Irving has played this season, he has averaged 28.5 points, 7.2 assists, 5.4 rebounds and 1.1 steals over 33.8 minutes per game while shooting 44.4 percent from the floor, 34.1 percent from three-point range and 93.7 percent from the free-throw line.
Taurean Prince added 14 for the Nets, who shot 53.2% and beat the Hawks for the eighth straight time. Trae Young is out for the Atlanta Hawks.
Brooklyn shot 70% and held a 37-16 lead after one quarter when LeVert hit a 17-footer at the buzzer.
Cam Reddish's 20 points were a team high and it was also the second most points the No. 10 overall pick scored in his rookie season as Reddish scored a career high 25 points against Brooklyn back on December 4.
