The idea for American 7s came to Ryan DePaul late in 2002. His High School Football playing career was over and there was no possibility of playing College Football. He was playing pick-up, no pads or helmet football in parks and thought it needed codifying, so in 2005 he began to develop 7v7 No Pads, No Helmet, Tackle American Football.
In 2014 he was approached by lifelong friend and entrepreneur, Sener Korkusuz about launching the League to Major League level. Soon afterwards the American 7s Football League was born, starting its first season in March 2015. [Ref: 1]
