What does the term 'jammer' refer to in roller derby?

The term 'jammer' specifically refers to the player responsible for scoring points in roller derby. This player is the key offensive role on the team, as their primary objective during a jam is to lap the opposing team. Jammers score points by successfully passing members of the opposing team, with each opponent cleared earning them a point.

This role is crucial for a team's success, as the jammer's ability to navigate through blockers and identify opportunities for strategic movement can significantly influence the game. Moreover, jammers often exhibit a combination of speed, agility, and tactical awareness to outmaneuver defenders, making them a focal point in scoring dynamics during bouts.

The other roles mentioned, such as defenders, team captains, and timeout callers, contribute to the team's overall strategy and gameplay but do not directly involve the scoring mechanism that defines the jammer's role.
