PITTSBURGH (AP) — Dan Muse is the new head coach of the Pittsburgh Penguins. The Penguins hired the former New York Rangers assistant and tasked him with helping the franchise navigate a rebuild during the twilight of longtime captain Sidney Crosby’s career. Muse replaces Mike Sullivan. Sullivan and the Penguins split in April after a nearly decade-long tenure that included a pair of Stanley Cup titles. The Rangers scooped up Sullivan, naming him their coach in May. The 42-year-old Muse was hired after a monthlong search by Penguins general manager Kyle Dubas. Muse’s hiring leaves the Boston Bruins as the last of eight teams with offseason head coaching vacancies.
