This story is so very sad, I could not keep the tears from flowing as I watched it. A young man's life destroyed because someone did not pay attention to his symptoms, or ask any questions or the right questions. This is not a sprained ankle or shoulder separation, this is a violent injury to the human brain which does not heal quickly. The state high school leagues, the NCAA, and the NFL need to implement and enforce comprehensive concussion prevention and treatment plans at all levels.
