There's a new offense in high school football. It's illegal under NCAA and NFL rules, but it's not as non-traditional as formations under arena football rules. This offense is called the A-11. It's announced objective is to allow smaller players in smaller schools with talent an opportunity to compete with teams from schools with more big players.
It's controversial because football is a bastion of tradition. Change comes very incrementally.
I offer a simply proposal to "level the playing field" especially at the J.H.S. and H.S. level: just handicap the big guys with weight like horses are handicapped.
