People don't seem to realize that you don't need to hit your head to get a concussion. A high speed collision that jars your head and body enough to cause your brain to hit inside of your skull is all it takes. People get concussions all the time in car accidents, even when your head doesn't hit against anything.

Taking off the helmets is not going to get rid of concussions.

A collision sport like football is always going to have to live with a concussion problem to a degree.
