CHICAGO -- Luol Deng might lead the NBA in scoring if the Bulls played the Trail Blazers more often.

Deng scored a career-high 40 points to lead the Chicago Bulls to a 110-98 victory over Portland on Monday night. Deng's previous career best of 38 points, on March 26, 2007, also came against the Trail Blazers.

"I think it's just a coincidence," said Deng. "We just shot the ball well. We moved it and shot it well. You're going to get shots in different places [in our offense], so you've go to be ready."

Deng scored 16 points in the first and third quarters and shot 14-of-19 from the floor in the game. He passed his previous career high with a 3-pointer from the corner with 5:48 to play. The shot put the Bulls up 101-84.

"During the first two games, [Deng] didn't shoot the ball well, but I thought he played well," said Chicago coach Tom Thibodeau. "He's moving without the ball, he's cutting hard, he's making the extra pass and he's playing really good defense. Tonight, he was terrific offensively. His body was in [constant] motion and he got out and ran the floor well."

Derrick Rose, who entered the game as the NBA's leading scorer, added 16 points and 13 assists for Chicago (2-1). The assist total matched his previous career high set against Utah last March.

"My whole goal was to see how I could control the game," Rose said. "They were keeping two people on me, so I had to pass the ball. Tonight, we were knocking in shots."

The Trail Blazers entered the game 3-0, with all three of their victories coming as a result of fourth quarter comebacks. Portland outscored opponents 85-49 in the final quarters of its first three games, but were unable to mount a sustained rally against the Bulls.

"We just didn't have it tonight," said Portland center Marcus Camby. "It would have been great to go undefeated but we lost tonight."

Portland climbed out of a nine-point hole with a 17-3 run to finish its game in New York on Friday night. This time, reserves Dante Cunningham and Armon Johnson scored on layups on back-to-back possessions to cut Chicago's lead to nine with 3:51 to play. Was another rally in the offing?

Not this time. Kyle Korver's 3-pointer with 3:01 to play put Chicago up 105-92 and the Blazers weren't able to get closer than 12 points after that.

LaMarcus Aldridge scored a season-high 33 points for Portland, almost single-handedly keeping the Blazers in the game through three quarters. Aldridge was originally drafted by the Bulls in 2006 but was traded the same day in a deal that sent fellow draftee Tyrus Thomas to Chicago.

"They tried to get me off the block," said Aldridge. "But I had a pretty good rhythm going."

Aldridge surpassed his previous season best of 20 points in the first half, during which he scored 22 points.

"His catches were a little too easy," said Thibodeau about Aldridge's big night. "We gambled too much and got caught off to the side."

Brandon Roy added 17 points for the Blazers on 4-of-12 shooting.

Deng scored 16 points in the first quarter, much of it coming in transition, where Bulls outscored the Trail Blazers 12-0 and built a 32-21 lead. The Blazers entered the game as the NBA's top three-point shooting team, but went 0-for-3 from there in the opening period and 0-of-14 in the game.

"We definitely need to play with more energy," said Portland coach Nate McMillan. "Our first unit gave up 32 points in the first and third quarters.

"Defensively, I think we're playing soft."

Chicago's Joakim Noah, who entered the game as the NBA's top rebounder in the season's early going, had 10 points and 10 rebounds in 42 minutes, but this night belonged to Deng.

"[Deng] is probably the X-factor on their team to get them to go where they want," Camby said.
