Patrick later became a top scorer, leading the league in goals (1942) and earning All-Star nods. His career was interrupted by World War II service, forcing him to shift from forward to defenseman upon return. Though his playing days wound down, his legacy was far from over.

Transitioning to coaching, Patrick enjoyed success with the Rangers and Boston Bruins, leading the latter to multiple playoff appearances. As Bruins' general manager, he built championship contenders, laying the groundwork for future victories. Finally, he became the first coach of the St. Louis Blues, guiding them to three Stanley Cup Finals in their infancy.

Lynn Patrick embodied the "Patrick Dynasty," leaving a lasting mark on the NHL as a player, coach, and executive.
