Taj Gibson dunked over Dwyane Wade early in the first half of Chicago's game one 103-82 win over the Miami Heat.
The emphatic dunk set the tone for a second half rout by the Bulls, who used a combination of stifling defense, a deep bench and high percentage scoring to snuff the Heat's big three.
LeBron James went 5 for 15 from the field, Wade went 7-17. Chris Bosh scored 30, but wasn't a factor late, as the Bulls held the Heat to 34 second half points.
The Bulls hit on all cylinders. Luol Deng had 21 and Derrick Rose had 28 to lead the bulls.
For all the leadership of the Bulls first team, the much vaunted bench also played up to its name. The combination of C.J. Watson, Omer Asik and Ronnie Brewer helped pull the out of reach of the Heat late in the fourth quarter. And Taj Gibson played like a man possessed, blocking shots, dunking on Wade and contributing a nifty put back dunk after he came flying in from the baseline.
The Bulls now take a 1-0 lead on the Heat. They'll play next Wednesday at the United Center.
