Ryan left the Packers after only one season, and Lambeau became player-coach. However, during the team's first season, Lambeau, as team captain, handled many of the duties associated with a head coach in modern times. In the early days of pro football, the head coach was not allowed to talk to the players during the game. Thus, Lambeau was the team's on-field leader during games, including play calling. He was also responsible for signing players and running practices. For these reasons, the Packers recognize Lambeau as the team's first head coach.
