"Mike Dunleavy really had a heck of a second half," Budenholzer said. "Some of them were really well-contested, tough, difficult shots, and give him credit for making them."
Carlos Boozer missed his first Bulls game of the season due to a sore right knee. MRI results on the knee were negative and the Bulls are hoping the injury isn't serious. Gibson started in his place.
"The big thing is getting everyone back and healthy," Thibodeau said. "Hopefully, Carlos will be short term, which I believe he will be. This is the first time we've had the group relatively whole."
Butler and D.J. Augustin each had 11 points, and Gibson and Noah had 10 points and 12 rebounds apiece.
Scott scored 12 and Carroll had 10 for Atlanta.
The Hawks pulled within one twice late in the third quarter but were unable to pull ahead. The Bulls led 67-64 after three quarters.
"It was a close game and we just couldn't find a way," Budenholzer said. "I think we have to be a little smarter down the stretch. We have to compete every possession, every rebound."
Deng made a half-court shot at the second-quarter buzzer to give the Bulls a 50-45 lead at the break. Korver had made a 3-pointer with 2.9 seconds left to cut the Bulls' lead to 47-45 after they were ahead by as many as 10.
The Bulls led 26-18 after the first quarter.
