Jim Boylen has plenty of pet phrases. Role acceptance is one of them.

And if you want to get the Bulls coach rolling, ask him about Kris Dunn’s performance in that department.

“Big time. Big time,” Boylen repeated, for good measure. “He just wants to win. He’s the first guy in the breakfast room. You have to be in the building 45 minutes before [practice]. He’s in 1 hour, 45 minutes before. He does his workout 45 minutes before everybody else with Coach [Nate] Loenser. He is locked in. He cares. He always cared. And he’s playing winning basketball. I’m really happy for him.”

There may be no greater compliment from a coach to a player than to say one is playing winning basketball. Relayed Boylen’s comment, Dunn didn’t take it lightly.

“That means a lot. That’s what I try to do,” Dunn said in an interview with NBC Sports Chicago. “I come from a winning program at Providence. I know what winning looks like. And I know what it takes to win.”

Right now, that involves Dunn accepting his role as a reserve aimed at wreaking defensive havoc on opponents. When Dunn scores 13 points, as he did in Tuesday’s victory over the Knicks, it’s a bonus.
