I have been officiating high school football and baseball for the last 22 years, and college lacrosse for the last 8 years. I’ve seen many injuries that I feel could have been avoided if more emphasis had been placed on helping coaches, parents, and administrators protect their players. Everybody involved in sports, including doctors, should read the book Concussion Awareness , which focuses on awareness of what can and should be done to protect players. I can tell you that rules are also being updated and changed to protect the players. The NFL is setting a good example with its rule requiring players to get clearance from a doctor before returning to play.
