The Chicago Bulls were granted permission to speak with several assistants for the franchise’s head coaching job and interviews with candidates are well underway, sources told ESPN. No permission was necessary for former Brooklyn Nets coach Kenny Atkinson to interview, but new executive vice president of basketball operations Arturas Karnisovas and general manager Marc Eversley are talking to several assistant coaches still involved in the playoffs, including Milwaukee’s Darvin Ham, Denver’s Wes Unseld Jr. and Miami’s Dan Craig, sources said.
