How it happened: Brandon Bass led the Celtics with 14 points and nine rebounds, while Kevin Garnett added 12 points and 11 rebounds in a game that had plenty of poor offensive execution to go around. Jimmy Butler had a solid night with 11 points and six rebounds, but it wasn't enough, as the Bulls couldn't take care of the ball and struggled to find an offensive rhythm all night. The Bulls have now lost four of their past five.
What it means: Tom Thibodeau is never happy when his team loses, but he will be especially disgusted after this game. That's because the Bulls turned the ball over 22 times and looked terrible offensively. Nate Robinson struggled getting the Bulls into an offense, and the Bulls couldn't figure out how to break Boston's defensive pressure. This game was ugly and will leave a sour taste in Thibodeau's mouth as his beleaguered team heads into the All-Star break. For all of his flaws -- and there are many -- the Bulls are missing Kirk Hinrich and the stabilizing presence he provided on the offensive end.
Hits: Marquis Teague gave Thibodeau some solid minutes in the first half in place of Robinson. He finished the game with five points and three assists in 20 minutes.
Stat of the night: According to Bulls Radio statistician Jeff Mangurten, the Bulls' 22 turnovers are the most in any game of the Thibodeau era.
What's next: The Bulls head into the All-Star break with a 30-22 record. They face the New Orleans Hornets next Tuesday night.
