Jimmy Butler admitted Chicago and Miami have a dislike for each other, and he believes that intensifies the Bulls' hopes not to let the Heat three-peat.

"That rivalry, it's crazy," Butler said. "They're the back-to-back champions and when you think three-peat, you think Chicago so we can't let that happen."

Butler said the Bulls are not looking forward to watching the Heat receive their championship rings on Oct. 29, when the two teams are expected to open the season in Miami.

"I don't think anybody wants to watch that on our team so we won't pay too much attention to it," Butler said. "They deserved it. They won a championship, definitely, but they got to deal with the Chicago Bulls for 48 minutes coming out right after that, they get their rings."
