To Jimmy Butler, it's simple.

Whether he's averaging 45.2 minutes in the five games he started for Luol Deng or playing 31 minutes, 14 seconds in reserve of Deng and others, as he did during Monday's 93-85 victory over the Bobcats, his role remains the same.

"Rebound, guard and make some open shots," Butler said. "Starting gave me a lot more confidence. But I'm still able to do those things (off the bench)."

Indeed, Butler stole the show, backing up his promise with a career-high 19 points and six rebounds, playing at shooting guard alongside Deng for a long second-quarter stretch and most of the final 5:28.

"Jimmy's a big part of the team," coach Tom Thibodeau said. "Lu has been huge for us. We know we have flexibility. You do what's best for the team."
