How do you fix the NFL? Very complicated question and I'm sure the fix would have to be multiple things. You have extraordinary athletes that start training seriously at puberty. They are machines that are augmented through good diets, yes chemicals, and proven work out procedures. They are in fact lethal weapons, just like boxers. Every collision is like an auto accident. Yet for all the bodybuilding and muscle packing the brain is still only protected as it ever was. I think a big step would be going back to the old "pliable" helmets of yesteryear. Take away the weapon so the player doesn't lead with one of their most vulnerable body parts. Yes it would change the game, but you want to save it something radical is going to have to happen. Like I said, it would only be an initial change, more would have to happen. Offhand getting rid of Thursday night football would be a great start. Unfortunately to the owners the players are only meat.
