Concussion counts are not as objective as they may seem.
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.
I'll presume you are saying no to soft-shell helmets. They would help, but I know there have been other helmet improvements implemented that perhaps mitigate injury the same or better. We still see too many concussions and I would like to see players stay as healthy as possible over their careers. Overall it's better for the players and the game.
