We'll be super cautious and I suspect he'll be wearing a headgear the rest of his career (i.e. this year)

Helmets do nothing to prevent (or mitigate the impact of) concussion arising from head knocks. They are typically worn to protect structural damage, such as the fractured cheek bone that Ted suffered against West Coast (or in the case of Jude or Kirky, as an attempt to cover up a bleeding head).

liz do u mean like snowboarders shouldn't wear helmets ?

i thought tests proved 20% reduction of impact for football helmets?

As Liz was saying, it protects you from structural damage, but your brain can still suffer from shock. Study done by NFL proves that as explained in the movie Concussion.

wow..............i wasn't aware to be honest

the hits i have taken in the old days without a helmet were massive when snowboarding

the crashes I've had since with a helmet have felt much less but now i know that it is quite minimal the protection to the brain when wearing a helmet

Doesn't make sense.
Wrap 4 pillows around your head and it will reduce the impact of your head on the ground.
Helmets must do the same thing to a lesser degree.

There's a lot more "give" in pillows, not so much in helmets.

This works for me.

That's what I'm saying. I'm using pillows as an extreme.
Given that the helmets aren't made of just plastic, and that they contain some padding, it doesn't make sense that they have no effect on softening the blow of the head to the ground.

[mariachi]

Concussion is the result of the brain "bouncing" off the inside of the skull. A helmet reduces the external impact of, say, forearm on head or head on turf, but if there's sufficient force, then the brain can still bounce off the skull and result in concussion. Witness the incidence of concussion in American football.

The thing with high impact head injuries, of the head hitting the ground is the sudden deceleration of the cranium as it impacts with the ground.
The brain is essentially like jelly in a solid bowl (the bowl being the skull in my example). Put a helmet on the bowl and drop it. The helmet stops the bowl from breaking, but as the bowl suddenly decelerates (ie hits the ground and stops all downwards momentum) the brain (jelly) itself isn't secured in the skull (bowl) buy much so it continues its forward momentum essentially squishing itself against the skull. As the head bounces back up, the brain is propelled back in he opposite direction, hitting the back of the skull.
Now, there are obviously some attachments to the brain, but these are soft tissues & blood vessels and essentially a little tenuous, they are prone to tearing with the traumatic high impact.

A cushioned helmet will offer some protection compared to nothing, as any padding will offer some protective deceleration of the head (and consequently the brain in the head) the debate will be how negligible this is (answer: probably pretty negligible given the force vectors involved.)

That was my only point.
I wasn't trying to make out that a helmet is the answer to concussion, but it must help to some degree, the degree of which is somewhere between relevant and negligible.
Not sure where it lands, but it may not be as negligible as you think.

I fully understand how concussions happen, hence my analogy to the extreme of pillows wrapped around a head.
Of course the pillows will dissipate the force with which the head makes contact with the ground, just as a helmet will (however negligible)

Heeney looking a bit tired?

Heeney looked he was struggling with the thompson match up. Was rattled by thompson's filthy behaviour and just couldn't get involved. Heeney was thrown up the ground to try and have an impact on the game.

[ugg]

Thrown up the ground is one way to put it, he was used as the spare man in defence at times and curiously most of the time was positioned right on the goalline by himself.

I've seen a few tired looking teams this weekend, including the Giants and Geelong. GC are a mess. They are coming back from the west coast and on a six day break. They are playing a ressies side with only a few listed players.

There's nothing to be gained by playing against GC reserves, particularly for Reid, who would be a handy inclusion for the Giants game. He might as well play in the seniors this week.

Abe Davis played in defence last game and looked okay. I would bring him in as well. And maybe even give BJ or Rose another go. I'd like to see how our forward line looks if we went a bit taller. I'm not worried about Patton when we play the Giants, but Cameron and Lobb pose a challenge as they are both tall and mobile, not like North forwards who we handled easily with a small backline.

Out: The 3 most tired, sore players.
