What is the primary role of the blocker in roller derby?

The primary role of the blocker in roller derby is to provide support for their jammer while preventing the opposing jammer from scoring. Blockers are essential to the strategy of the game; they form a defensive line to hold back the opposing team's jammer while simultaneously creating openings and paths for their own jammer to navigate through the pack and score points.

By effectively working together, blockers can disrupt the momentum of the opposing team's jammer, employing tactics such as body positioning and strategic hits to impede their progress. At the same time, they work to assist their own jammer by clearing obstacles or shielding them from the opponents. This dual role of both support and defense is what makes blockers crucial to a team's overall success during a bout.
