>> you know, i really don't think there's anything that you can actually do to make the game safer. yeah, there's equipment and so forth. but you're talking about the brain. the helmet covers and protects the skull. it does not protect the brain. so when you have that rapid movement, when you have the brain moving forward when someone gets hit and then the brain hits against the inside of the skull, you know, that is when you sustain concussion. nothing is going to prevent that from happening. more and more, you hear players talk about when they sustained concussions. when you play against one another, you don't share. you don't talk. you keep those things to yourself because it really does show a sign of weakness and you don't want people to know what's going on. but when you retire, you start talking to other players about what happened and it becomes clear that there was a lot of damage that you either received or you gave out to players who
