A convoluted topic for sure. The NFL has resisted the issue for a long time and they still try to protect the brand. Players also want to play and will sometimes hide symptoms. Concussion numbers are still too high and solutions are evasive. Rules and even helmets have changed, but perhaps if soft-shell helmets (Great Gazoo style!) were used we’d see less concussed players. We would lose those sharp cracking sounds that exemplify the violence of the game, but less CTE and better player health is what we should absolutely be striving for.
