"Guys like that, you've got to guard them with your whole team, and they still have the ability to make," Thibodeau said. "You have to stay the course against them."
Harden's 27 led the Rockets to a 101-90 victory over the Bulls on Wednesday night. Fifteen came in a pivotal second quarter that helped the Rockets build a lead that they never relinquished.
The Bulls lost their third straight game for the first time all season and have now lost four of five. The Rockets have won five of six.
Harden overwhelmed the Bulls in the second, menacing small forward Jimmy Butler in multiple one-on-one battles to score 13 consecutive points in the fading minutes of the first half.
He was more excited about the Rockets' defense that held a versatile Bulls offense to just 90 points.
"Every night, that's our motto is to be aggressive," Harden said. "We have so many guys that can come in and play that we don't worry about getting tired."
Fatigue and a lack of consistent effort seemed to be a common theme in the Chicago locker room following the loss.
"We can't afford to have those lulls," Thibodeau said.
Jimmy Butler led Chicago with 27 points, and Derrick Rose scored 23, playing in his 12th consecutive game for the first time since the 2010-11 season.
"It shouldn't be anywhere near this, knowing how talented we are and knowing how much guys really want to win," Rose said. "We've got time, but we've got to figure out a way out."
Despite the win, the Rockets missed Dwight Howard's boards. The center was out for a fifth straight game with a right knee injury and Chicago's big men dominated the glass, 60-47.
Joakim Noah pulled down a season-high 19 rebounds in 32 minutes. However, he had just one point, finishing 0 for 8 shooting.
"We're playing hard in spurts, but we just can't do it for 48 minutes right now," Noah said. "We've got to figure it out or it's going to be a long year."
In all other categories, however, the Rockets owned Chicago's big men, outscoring the Bulls 50-28 in the paint and notching eight blocks to just five from Chicago, who entered the game as the league's leaders in blocks at 6.7 per game.
"I thought we tried to attack the basket well, especially early," Rockets coach Kevin McHale said. "We weren't getting to the line very much, but we just kept attacking."
