Because the signs and symptoms of concussions are not obvious as a
broken leg or a sprained ankle and are often very subtle, because the vast majority
don't involve a loss of consciousness, and because self-reporting by
athletes is critical to the detection and treatment of concussions, the
only way parents can sit in the stands without worrying sick about what
might happen if their son or daughter suffers a concussion is if they
know they and their child's program takes
concussions very seriously and that every member of the team is using the same playbook.
