Jammer is the point scorer for each team. Jammer must lap the pack (all the other girls) at least once in order to begin scoring any points. Once a jammer laps the group (1st jammer for a team b/c lead jammer) each person from the opposing team that the jammer passes is a point. The Pivots control the pace of the pack so that the pack isn’t going too fast (or slow) for their team’s jammer. The Blockers set up the pack to make sure that the opposing team’s jammer doesn’t pass them (if the jammer doesn’t pass at the hip/shoulder (it depends on the leagues rules) then a point doesn’t count) but are also there to make sure that THEIR jammer passes them. They do this for 2 minutes, unless the lead jammer calls the jam before the clock runs out.
