It is good to see high school programs acknowledge this issue. Hopefully it means they are taking measures in their training and techniques to reduce the risk of sustaining concussions.
I do wish that football wasn't the sole target of this problem in the media. They use it because of its popularity in this country.
Very few parents are afraid of letting their daughters participate in sports even though some studies show the average female athlete in most sports is more likely to suffer a concussion, or at least be diagnosed, than the average football player.

The recent study going around the media cycle about CTE does not tell anyone that most, if not all, of the brains donated for research are from athletes who were suspected of having the problem. Many of these NFL and college players were from the 70s, 80s, and 90s when steroids and hard party drugs were prevalent, possibly affecting brain chemistry, and not tested for, and concussion awareness was non existent.
I would suspect if it was a blind sample of modern players results would be much different, because of awareness and including those that don't believe they have a problem. Can't test for CTE without a deceased brain, unfortunately.
Sports, and life in general, are dangerous. We won't be able to eliminate concussions and CTE, but every reasonable step should be taken. Just don't go wrapping everyone and everything in bubble wrap for the rest of their lives.
