-they do have beep frisbees that are light weight and foam. Super cheap as well.
-allow the frisbee to hit the ground/ offense is allowed one drop while in possession.
-allow hand offs during the game
-start off with a game like "newcomb" where the ball can hit the ground and you can play it off the ground.
-obviously if a lightweight beeping ball is available.
-catch the ball first then work on returns to the other team.
-designate one player on each team to call out who should hit the ball.
-multiple hits beyond three per side
-allow for underhand passing without calling carries
-allow to play the line and rush the quarterback. Quarterback should wear a beeping pinnie to assist with positioning.
-visually impaired athlete could be qb and pass to one person, who can then make one more pass before the defense can defend.
