Football is a risky sport. Rugby must rank as the second most deadly sport after fighting if all sports are considered harmful. What exactly does a football helmet do then? Actually, this issue can be resolved quite easily. The air cushion in the player's helmet serves as both a fixation and a protective mechanism. During heated NFL games, mouthguards are crucial to prevent injury to players' faces and teeth. Local bruising, skin abrasions, joint sprains, muscle strains, and other injuries are more frequent in rugby, but concussions are specifically related to rugby and cannot even be considered rugby ailments. Even with helmet protection, severe injuries cannot be totally prevented

It's seen as a revolutionary piece of sports gear, the safest helmet in NFL history. Many NFL players wear this helmet. But it was designed to soften the blow to the head of NFL players. The scientists, neurosurgeons and engineers who designed the helmet made it clear that it would not prevent concussions. No helmet can do that.
