The role of a "captain" in team sports is significant as the captain acts as a leader on and off the field. They are responsible for motivating teammates, facilitating communication with coaches, and making tactical decisions during games. Captains often play a key role in maintaining team morale, addressing conflicts, and setting an example through their work ethic. They may also represent the team during official events, contributing to team cohesion. A good captain enhances the overall performance and unity of the team, fostering a sense of responsibility and accountability among players.
