The A-11 offense was developed by Kurt Bryan, coach of the Piedmont High School Highlanders in Piedmont, CA, and Steve Humphries, the school's director of football operations, who initially uncertain of its legality, submitted the concept of the offense to the National Federation of State High School Associations and the California Interscholastic Federation and had it approved. Piedmont High School then implemented it during the 2007 football season-losing their first two games before winning seven straight to finish with a 7-3 record.
The A-11 Offense (All Eleven Players Potentially Eligible) is an innovative new offense that blends aspects of almost every type of offense in the history of football such as the West Coast, Spread Option, Run and Shoot, Shotgun Zone Fly, Wing-T, Single Wing, Notre Dame Box, Triple Option and Veer just to name a few. Teams can use the A-11 as a “package” to supplement their own offense & feature up to eleven players as potential threats, and even two quarterbacks in the shotgun!
HOW IT WORKS
The A-11 features up to all eleven players wearing an eligible receiver jersey number, either 1-49 or 80- 99, with two quarterbacks (1 and 2) in the shotgun formation at 7 yards, and with nobody under center -thereby meeting the criteria for a scrimmage kick formation. In “base” sets, the A-11 Offense has a center, and a tight end on each side (U and Y), and three wide receivers to the right, and left respectively. By spreading the potentially eligible receivers across the entire field, it forces the defense to account for every possible receiver on each play. Of course, on any given play, only six of those players can go downfield to catch a pass, and the five “covered” players remain ineligible to catch a downfield pass on that particular play.
Here's the A-11 in action:
