It’s wrong to say that the football world only came to realize that concussions were dangerous to football players within the past 10 years. Vast improvements have been made in the diagnosis and certain dots have been connected. But anyone trying to claim that we didn’t know that concussions were serious just didn’t care enough about the health of their players to pay attention. Doctors and coaches of all sports, including football, have known for decades that repeated blows to the head are extremely dangerous to the health and well being of their players.
No improved helmet or rulebook will cause the necessary shift in the attitude about concussions; the mentality of coaches has to change.
