AFL Rd 19 2023 Pre Game Prognostications Carlton vs West Coast at marvel

[kruddler]

Helmets don't stop concussions, the mechanism inside the skull still occurs when the head takes a knock whether you are wearing a helmet or not.

Not entirely true.

Its the sudden stop that forces the brain to move inside the skull.
If the stop is less sudden, courtesy of some kind of cushioning (be that a helmet, or an air bag, or even the crumple zone on a car) then the force on the brain is less, thus less chance of a concussion.
