PITTSBURGH (AP) — Dan Muse is the new head coach of the Pittsburgh Penguins. The Penguins have 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 near decade-long tenure that included a pair of Stanley Cup titles. The Rangers quickly scooped up Sullivan, naming him head coach in early May. The 42-year-old Muse was hired after a month-long search by Penguins general manager and director of hockey operations Kyle Dubas. Muse’s hiring leaves the Boston Bruins as the last of eight offseason head coaching vacancies.
