Preface - National Bout League
The National Bout League brings eight teams together across two conferences and one increasingly valuable prize. Built from roller derby’s mix of speed, contact, personality and self-invention, the NBL has grown into a national professional competition without losing the names, colors and rivalries that made the sport worth watching in the first place. Its rules share the same foundation as traditional flat-track derby, but the league has developed its own professional variations around roster management, scheduling and competition.
New this season is the Starting Six, with each team declaring one jammer, four active defenders and a Rotational Defender who can cycle in and out between jams. Only five skaters are on the track at once, giving teams more tactical flexibility while allowing bruised or winded defenders to recover without being permanently replaced.
The league is split between the Sunset Conference in the West and the Liberty Conference in the East. Each team faces its conference rivals through the regular season before the top two advance to a conference final. The winners meet for the championship.
At the center of it all is the Kingpin Trophy, awarded to the team that survives the season and wins the Kingpin Cup. Part joke, part crown and now the most recognizable piece of hardware in the league, it has become the thing every roster claims not to think about until the moment it is close enough to touch.
Eight teams begin the season. Two will reach the final. One leaves with the Kingpin.
