In roller derby, jammers need blockers. Without blockers, jammers would get smashed and left like roadkill on the flat tracks. In addition to offering protection, blockers impede the progress of the skaters on the other team, providing jammers an opportunity to score points. For the Kansas City Roller Warriors All Star team, nobody paves the way like Eclipse (also known as Kristin Clarke). And no one capitalizes on an opening like Kelley Young (the jammer formerly known as Snot Rocket). The deadly duo led the All Stars to wins over teams from Providence, Boston, Atlanta, St. Louis, Nashville and Seattle.
