As a recipient of 4 concussions I sympathize with these players. It absolutely takes a toll on you mentally when you cannot do anything. Sitting in a dark room with no sunlight and barely any noise was draining. Without my family and oddly enough my pet cat, I'm not sure how I would have survived. That's not to mention the mental anguish it takes when you think you're "healthy" again. You aren't. Sleeping,eating, not to mention training was miserable. I feel sorry for anyone dealing with head issues that doesn't have access to the help they need.
