Football, as you know, is a high contact sport. Anytime two (or more) people make contact as they do in football, people are going to get hurt. Obviously, the players and the others in the sports leagues want to minimize injuries as much as possible. This is why manufacturers are coming up with new and improved sports protection whenever they can.
However, the only way to completely avoid injury from a sport completely is to not play it. Since this isn’t a good option, the next best thing includes being in as good shape as possible and to use safety equipment at all times in the way it is supposed to be used.
