The A-11 offense is an offensive scheme that has been used in some levels of amateur American football. In this offense, a loophole in the rules governing kicking formations is used to disguise which offensive players would be eligible to receive a pass for any given play.[1][2] It was designed by Kurt Bryan and Steve Humphries of Piedmont High School in California.
The scheme was used at the high school level for two seasons before the national governing body of high school football, the National Federation of State High School Associations, closed the scrimmage kick loophole in February 2009, effectively banning important facets of the offense.[3] Due to rules regarding player numbering and eligible receivers, the scheme as originally designed is not usable at most levels of football, including the National Football League and college football.
The A-11 offense was to be the basis of the A-11 Football League (A11FL), a professional football league which was scheduled to play its first season in 2015. However, after announcing franchises names and scheduling "showcase games" in early 2014, the A11FL folded before taking the field.
