Brooklyn lead by as many as 12 points, but once again an offensively stagnant fourth quarter doomed them in the end.
Chicago outscored the Nets 34-18 in the final frame Cam Thomas tallied the first double-double of his career with 24 points and 10 assists, Tyrese Martin added 19 and Nic Claxton chipped in 18.
The Nets likely waived goodbye to their likelihood of putting a scare into the Bulls for the final play-in spot.
The Nets take on Boston Saturday night back at Barclays Center.
