The Pittsburgh Penguins officially announced the departure of head coach Mike Sullivan after a decade-long relationship that yielded two Stanley Cup championships in 2016 and 2017. Despite his success, the team opted for a change following three seasons without a playoff appearance. Penguins captain Sidney Crosby expressed gratitude for Sullivan's impact on his career and the team, highlighting his commitment to winning and personal growth. General manager Kyle Dubas noted the decision was difficult but necessary as the organization navigates a transition period with core players like Crosby, Evgeni Malkin, and Kris Letang nearing the end of their careers. Sullivan, now a leading candidate for other coaching vacancies, leaves behind a legacy as the franchise's winningest coach.
