The Nets moved into a tie for sixth place in the Eastern Conference despite missing a staggering 21 free throws to give the Hawks a chance at the end. After Joe Harris hit one of two foul shots with 16.3 seconds remaining, Trae Young dribbled down the clock and passed to 42-year-old Vince Carter, who missed a 3-point attempt at the buzzer.
John Collins finished with 33 points and a career-high 20 rebounds for Atlanta, and Young had a triple-double with 23 points, 11 assists and 10 rebounds.
Young and Collins combined to score 27 points in the fourth to keep Atlanta close. Young hit a pair of free throws with 5:11 left gave Atlanta its first lead since the first quarter, but Brooklyn never trailed again after D'Angelo Russell's 3 made it 111-109 with 1:41 remaining.
The Nets improved to 17-5 since Dec. 7 in games in which the margin has been five points or fewer in the final five minutes.
Atlanta, still in rebuilding mode under first-year coach Lloyd Pierce, has lost three straight.
Brooklyn took its first lead at 13-12 on Russell's straightaway 3, and their second when Dinwiddie's bank shot made it 22-21. With the score tied at 41-all in the second, the Nets closed the quarter on a 15-6 run.
They aggressively went to the rim in the first half, resulting in 23 free throws, but Brooklyn missed eight times from the foul line to set the tone for an even worse second half.
