Another former pro football star, now in declining mental health, has promised to donate his brain to research on CTE. His son was also a victim of football, a quadrapelegic as a result of a neck injury. They, like many other critics, believe that youth football, especially for younger players, should be banned.
Meanwhile, as every season, very serious football injuries continue to pile up.
One straightforward rule change could probably drastically change injury rates - ban unlimited substitution. Because of unlimited substitution, line positions in football are now dominated by 330 lb. behemoths who are so strong that they routinely injure others and themselves with size and strength. Current rules mean that they play in 12 second bursts for a small fraction of the clock time. If players had to play most of the game, offense and defense, with much shorter breaks, linemen would quickly get 60-70 lb (or more) lighter.
