@FlashMobOfOne @pabloniusmonk The NFL doesn't dictate how the sport is conducted at the youth levels of play, though, and it wouldn't be the first sport that would play differently at the youth, college, and pro levels.
Unfortunately, I suspect making football safer would mean changing it into a pretty different sport, given the way that the trend towards head injury is the result of changing the rules to reduce knee injury. I doubt fans and parents would accept a safer game.
