Hall of Famer
Concussion is usually about the head rotating suddenly or stopping suddenly and thus the brain smashing into the inside of the skull. The theory is that standard helmets cushion some of the force of direct impact, but little of the rotational forces. Hopefully they can invent helmets that are more effective at stopping the rotational forceCan never protect someone from a concussion 100% depending on how much force is applied on the head because ultimately the brain surrounded by water and can move freely. But the cushioning from the helmet can negate a lot of force so the head doesn't take the full brunt of a lot of head to head or limb to head incidents on a sports field.
