Smith, who has been mired in a prolonged shooting slump, sulked on the sideline Saturday night, when he played a season-low 12 minutes and scored just three points in a win over New Orleans.
On Monday night, Smith scored 12 points in nearly 28 minutes of play and helped the Nuggets beat the Charlotte Bobcats 104-93.
Denver coach George Karl was generally pleased with Smith's performance and his demeanor on Monday night.
"I still wish he'd shoot the ball better, but in general he played with a focus and an intensity," Karl said. "I think he knew it had to be a serious game and he gave us a serious game."
Smith, who was 5 of 14 shooting from the field, left the locker room without speaking to reporters. However, he spoke with the team's Web site.
"I don't worry about that stuff no more. They're out there just trying to sell newspapers, so they can say what they want," Smith told the site.
