When the Tulsa Talons bolted for San Antonio in 2011, the city lacked a professional indoor football team for the first time in more than a decade. That didn’t last long, however. The Oklahoma Defenders promptly filled the role in 2012, playing their inaugural season as part of the American Football League. In 2013, the team left the AFL to join the Champions Professional Indoor Football League. The move to the CPIFL was complemented by the addition of radio broadcasts of every game, letting fans listen in whenever a big tackle is made or the opposing coaches settle a tie by jousting each other atop offensive linemen. At their games, Defenders keep fans pumped up with plenty of off-the-field entertainment, including appearances from mustached mascot Billie the Regulator.
