Formerly the Lingerie Football League, the Legends Football League stands as the "fastest-growing pro sports league in the nation" according to NBC Sports correspondent Rick Chandler. That success owes much to the league's unique format, which pits two exclusively female teams in alluring uniforms against each other in full-contact football games on a 50-yard field. Donning football pads and helmets over their revealing performance wear, the female athletes block, juke, and sprint uninhibited by such frivolous gear as the NFL's heavy chainmail hauberks.
