> In the NFL 18.8% of injuries occur at or above the shoulders, the area where athletes wear the most protective equipment. In the AFL 11.5% of AFL injuries occur in this area, where they wear virtually no protection.

Helmets enable players to weaponize their heads, like this recent hit (Vontaze Burfict's suspension earning HIT on Anthony Sherman): https://www.youtube.com/watch?v=_7qQtadYqsI and many others demonstrate. I believe removing helmets would mitigate this behaviour and increase the long term health of football players. Looking for data on Aussie rules, this is not quite what I was hoping to find, but interesting: https://en.wikipedia.org/wiki/List_of_Australian_rules_footb...

Without question Aussie rules has its share of devastating brain injuries: https://www.youtube.com/watch?v=s1aU0hz5Tf8. Plenty of concussions and fencing responses in that clip.

At 33, I've stopped watching North American football altogether because the violence turned me off. 10 years ago it was my second fav sports (to Hockey).

With relatively rested players lining up against each other on every down the situation is much different from players chasing each other on the field like they do in AFL.

WRs for example have a somewhat similar situation to AFL players since they are mostly being chased by the defense and they don't get nearly as many contact injuries as RBs for example. Not to mention they are protected by (frequently controversial) pass interference rules.

From what I gather, introduction of the helmets back in the day reduced injury rates.

There's also suspicion, if I recall correctly, that the routine repetitions of linemen taking knocks to the head in practice does more long term damage than what we see on game day. This may be more pronounced in high schools and to a lesser extent, college, where the coaching can be more suspect.

Yes, research has suggested that a number of smaller collisions can cause damage even if a player never suffers an actual concussion. A helmet also only protects you from external trauma. It acts as a second skull. But the problem isn't always from external trauma. If you are moving at speed and you are put to an immediate stop due to a collision with another player, your entire body experiences a lot of force. Your brain will end up colliding with the inside of your skull due to inertia regardless of whether you were hit in the head or not. That is why simply cutting headshots out of the game or removing helmets won't be enough to protect players. It really gets down to the fundamental nature of football and the physics of its collisions.

Analogy I've stolen from a Uni. of Toronto brain doctor: fill a mason jar (skull) with water (cerebrospinal fluid), and throw in a golf ball (brain). Shake the jar, the golf ball will hit the side of the jar.

You could bubble wrap the jar (helmet), but the ball will still collide with the inside of the jar.
