3. Kelly Griffin
Captain of the United States’ women’s sevens team, she was a key reason the US shocked the rugby world by winning the bronze medal at the 2013 Rugby World Cup Sevens. One of the first women ever in the US to be able to be a professional rugby player (and be paid for it), she is also the longest-tenured member of the US sevens squad, and captained the team in the 2016 Summer Olympics.
