"I'm blessed to be here for one," Butler said after Tuesday's practice. "I just got through talking to (Bulls GM) Gar (Forman) and thanking him for the opportunity to be here and be around these guys, great players, great basketball people, and an amazing organization."
Butler, who was the Bulls' first-round pick in 2011 out of Marquette, is expected to be a significant contributor off the bench this season. He spent the summer working on his game so he would be ready for the opportunity.
Butler is expected to fill the role Ronnie Brewer played for the Bulls last season as a defensive swingman off the bench.
"I think they just see how hard I work and how much I want to stay here," Butler said. "Day in and day out I'm here early, and I leave late but I learn a lot, too. I thank my teammates every day for giving me another opportunity because they show me how hard you have to work in order to stay here so I'm just following in (Luol Deng) and Rip (Hamilton) and Kirk's footsteps."
Butler averaged 2.6 points and 1.3 rebounds last season.
