"My confidence was real high and the rest of my teammates came out and played wonderful," Rose said on TNT after the game. "Everybody played a good game."
After Joe Johnson scored 34 to lead Atlanta to a Game 1 win, the Bulls held Johnson to 16 in Game 2.
"We made sure we were in front of him," Rose said. "He's a great player, and we had to make sure we contested all his shots, rebound the ball and run."
As far as his ankle, Rose, who was 10-of-27 from the field, said: "I'm good. I just missed some shots I normally make."
The series shifts to Atlanta for the next two games with Game 3 on Friday.
"We have to come out and be aggressive the whole game like we did tonight, make sure we put a lot of pressure on them and play team basketball," Rose said.
