Exactly, and this clanging of the brain inside the skull does not require any direct trauma to the head......just any deceleration event to any part of the body. The player can be hit at body level (without head contact) from the front, from the back or from the side and create much the same brain trauma.....especially as it repeatedly happens throughout each game at most positions........over periods of years. CTE can occur with no previous history of direct head trauma concussion. It can occur with repeated asymptomatic subconcussive hits.
So then what is really needed to prevent concussions are seatbelts and airbags for our brains inside of our skulls. To further clarify what I've tried to explain, let's look at "shaken baby syndrome." Shaken baby syndrome is caused by shaking a screaming baby back and forth to make them stop crying. Even though their head never hits anything, the shaking leads to brain damage. Would wearing a baby helmet have helped? Of course not. So how can a helmet possibly eliminate concussions in football. It can’t. Any protective device that claims to prevent concussions in a contact sport is false advertising and may only serve to give athletes a false sense of security.
