As if Jimmy Butler didn't have enough to process this summer as he prepared to start at shooting guard for his first time, a friend had to open his big mouth.

"I never thought about this until he mentioned it to me, but Derrick (Rose), Lu (Deng), Jo (Noah) and Booz (Carlos Boozer) had started together for so long," Butler said. "Sometimes, I'm thinking I don't want to step on anybody's toes. But then they tell me to be aggressive, so that's how I have to approach it."

Indeed, the surest way for Butler to draw coach Tom Thibodeau's ire is to pass up open shots. With Rose demanding so much attention, Butler must keep defenses honest.

"If they do sag off, I'm going to shoot it," Butler said. "Thibs is going to have something to say if I don't. It's all about getting comfortable, getting my legs up under me and making shots."

After Friday night's 97-73 victory over the Jazz, Butler is 4 of 16 on 3-point attempts.

"He's got to take the shots that are open and, if not, make the right play," Thibodeau said.
