 While the Browns' on-field play in 1956 was uninspiring, off-the-field drama developed after a Cleveland-based inventor let Brown test a helmet with a radio transmitter inside.After trying it out in training camp, Brown used the helmet to call plays during the pre-season with long-time backup George Ratterman behind center.The device allowed the coach to direct his quarterback on the fly, giving him an advantage over franchises who had to use messenger players to relay instructions.
