I did a paper on sports related injuries. Funny how the networks are starting to focus on this issue. I watched the Sunday Night NFL game and of course they made a point to focus on this issue instead of football. Concussions are one of the most common injuries in Football. Hitting your head on the ground while wearing a helmet usually results in some trauma. I don't think there's any way they can completely reduce head injuries. They can minimize them but not eliminate them. Usually landing on your back results in your head snapping back and getting your bell rung. I remember stingers when wearing some helmets and other helmets illuminated this problem. Banging heads with someone isn't as damaging as the noise. My ears would ring for a while afterward. It was always when I banged my head on the ground that I would get hurt the worst. I still don't like journalists focusing on this because their business is to report the game not get into saving players from injury. The teams medical staff do that enough. Only thing that can be done is change it to flag football instead of tackle.
