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.
From the A7FL website: “The A7FL field size is 100 x 37 yards and does not utilize the field goal posts. The narrower field width increases the pace of the action with fewer men on the field making for vicious hits while the 100-yard length maintains the grind. The quarterback has 4 eligible targets with 2 down linemen. Offenses can run bone or pistol, and there are no blitz restrictions for the defense.” [Internet] Available from: https://www.a7fl.com/about-a7fl/ [Accessed 17 March 2022]
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]
American 7s is neither 8v8 Arena Indoor Football, nor standard 11v11 American Football, rather a 7v7 hybrid of the two major American formats, played without pads.
