What is a "pivotal" position in roller derby?

In roller derby, a "pivotal" position refers to a role played by a blocker who possesses the unique ability to transition into a jammer by taking the star helmet cover. This element of the game is crucial because it allows for strategic flexibility; the pivotal skater can contribute to both defensive and offensive plays. When this player successfully takes on the jammer role, their team can capitalize on their skills to score points, potentially turning the tide of the game.

This concept showcases the importance of versatility on the track, as the pivotal skater can aid in blocking opponents while also being ready to score when the opportunity arises. The ability to switch roles mid-game adds a layer of complexity and strategic depth, making it an essential skill for high-level play in roller derby.
