Chicago Bulls president and CEO Michael Reinsdorf made it clear he wants coach Billy Donovan to remain in his job. He says that whoever the Bulls hire to run their basketball operations will have to work with Donovan if he chooses to return next season. Reinsdorf says anyone who doesn't want to do that is probably not the right candidate for the club. Reinsdorf spoke Tuesday. The Bulls made sweeping changes to their front office on Monday, firing executive vice president of basketball operations Arturas Karnisovas and general manager Marc Eversley after a six-year run produced one playoff appearance.
