Chicago Bulls shooting guard Jimmy Butler said his team would not allow the Miami Heat to win their third straight championships, claiming they are going to give the defending champs a tough battle when the two Eastern Conference powerhouses opened their regular-season on Oct 29.

Butler, who averaged 13.3 points and 5.2 rebounds last season, believes the Bulls will be a real threat to the Heat's three-peat aspirations, especially when All-Star point guard and former MVP Derrick Rose returns from a year-long knee rehabilitation.

"That rivalry, it's crazy," Butler told Nick Friedell of ESPN via Real GM. "They're the back-to-back champions and when you think three-peat, you think Chicago so we can't let that happen."

The 27-year-old Butler said the Bulls are planning to spoil the Heat's championship celebration right after LeBron James and company receive their second championship ring on opening night.

"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."

Butler is expected to start in his third season with the Bulls, giving the ball club a guard with the ability to create his own shot and knock down baskets from the perimeter consistently.

Moreover, Butler's development will give the Bulls another go-to-guy alongside Rose in the backcourt.
