Scrap helmets and pads, improve safety and technique

sense being talked I like it, saw an article on NFL.com regarding heisman's introduction of the forward pass rule, when did that get introduced? obviously a revolutionary rule change and the man had a trophy named after him as recognition....is it pre-dating leather head days in which there was a form of grid iron in which there was no forward pass rule? Amazing to think that once upon a time that major part of the game didn't exist
