CHICAGO (AP) — Chicago Bulls executive vice president of basketball operations Arturas Karnisovas fell on his sword and vowed to make changes after the team he constructed missed the playoffs for the second straight season.

He said he takes “full responsibility” and promised to get creative in reworking the roster despite having no salary cap space. He’d like to re-sign DeMar DeRozan and plans to bring back coach Billy Donovan. But he struck a far different tone Saturday following a knockout loss to the Miami Heat in the play-in tournament after opting for continuity over change in recent years.

“I’m thinking about winning,” Karnisovas said. “That’s why I’m here. I’m not here to stay in the middle. The formula that came up three years ago, I thought it was working until a couple injuries. And we’re gonna have to find these answers in this offseason. Obviously, the results are not where we want it. I totally get it. And it’s on me to figure it out.”
