Maybe OSHA-mandated retirement at 25 will make NFL games a lot more like college games. I’d love to see comparative stats on long-term concussion-related ailments for professional football, rugby and Aussie rules football.
A little off subject but ... I remember a commercial (insurance, I think) using Dan Dierdorf as the spokesman and they actually showed a brief shot of him walking towards the camers .... and If I remember correctly, he had those orthopedic, padded shoes on and could barely walk and I thought ... man ... you crippled yourself playing a game.
I think the modern helmet is the cause of the problem. It allows excessive collision velocity.
Go back to leather helmets, and I bet the problem goes away.
