Pies and Tiges pushing to get an annual pre-season game for the "Charity Shield."

First one is being held this year.

I like the idea but I think it should be at Marvel instead of Ikon Park. AFL has scheduled pre-season matches at Marvel before and both clubs would draw the crowd. In exchange, reduce the amount of home games the AFL forces both sides to play at Marvel each season.

I'd even rather GHMBA to Ikon Park. Horrible ground.

Could someone please post mark Robinson's article on Nathan Murphy..

Just from the headline I agree

Unfortunately it when not if he gets concussed again

Even if you don’t know Nathan Murphy, you’ve got to love him.

He plays footy with flair and instinct. He’s brave above his head, he’s fearless and adept with his tackling and when he gallops at full speed, with his customary long hair flailing below his headband, he has the uncanny knack of timing his intercepts or third-man-up efforts to the precise moment needed for impact.

And good luck one-on-one, for he wins more than he loses.

But he shouldn’t be playing footy.

Of all the summer AFL announcements, the December 20 missive that declared the AFL’s concussion panel had passed Murphy to play in 2024, was the most astonishing.

Here is a bloke who has had 10 concussions through his junior and senior footy career, is at risk of long-term brain damage with further head knocks and the AFL, the AFLPA and most importantly Collingwood are putting him in a position where long-term damage is a possibility.

Ultimately, it was his decision to play on after suffering yet another concussion in last year’s Grand Final, and certainly the AFL, the AFLPA and the Pies did not deter him.

Perhaps they should have.

Crucially, when Murphy fronted the AFL’s concussion panel in the off-season it gave him the green light to play.

Asked who was on the panel and what the reasoning was behind the decision, the AFL would not release information on the why.

“The AFL chief medical Officer, Dr Michael Makdissi, coordinates the multi-disciplinary Concussion Panels that are made up of multiple members with expertise and experience relevant to the player’s condition being considered,’’ AFL spokesman Jay Allen said.

“This means that different people sit on different panels and any given panel may include neurologists, neurosurgeons, neuropsychologists, sports physicians, physiotherapists with expertise in neurorehabilitation, etc.’’

Thus, a bunch of experts said, despite the increased risk of long-term impairment, that everything was hunky dory.

It’s hard to argue against experts.

It’s easier to look at clinical research and the data found.

Released in December, 2023, an Oxford University study of 15,000 participants found that people who had suffered three or more concussions had “significantly worse cognitive function, which got successively worse with each subsequent concussion after that”.

Clearly, 10 concussions is not the cut off number for Murphy. What is then? 12? 13? 20?

Murphy is well and truly in the red zone.

A week after the Oxford University findings were announced, the Pies said in a press release: “The club doctor, Nathan and his parents appeared before the Collingwood Football Club board and the board - on the basis of the recommendations of the medical concussion panel convened by the AFL, recommendation of the club doctor and awareness and acceptance of risk associated with future concussions confirmed by Nathan and his parents - agreed on those bases that Nathan should be able to continue his career as a player at Collingwood.”

Read that again.

The Pies conceded there was an “awareness and acceptance of risk associated with future concussions”, yet still agreed Murphy could play on.

Is it up to Murphy to accept the risks or is it Collingwood’s responsibility to decide that the risks are too real?

Yes, they love him, but some tough love perhaps was needed.

God forbid Murphy is KO’d in Round 3 and it’s a doozy. It wouldn’t be Collingwood’s fault, however, because Murphy “accepted the risks”.

In essence, the Pies have allowed Murphy to roll the dice when the club shouldn’t have put the dice in his hands in the first place.

Some experts would say the Pies should’ve stopped Murphy from playing.

The concussion debate is rearing.

Last week, the Australian Institute of Sport recommended that players in community sport be stood down for at least three weeks if they have suffered a concussion.

In the AFL, it is 12 days.

The history of repeated head knocks is grim. Suicides are linked to head trauma (Danny Frawley and Shane Tuck) and more and more former footballers are reporting symptoms of CTE (chronic traumatic encephalopathy), which is a range of dysfunctionality.

In the women’s game, four women who loved playing Australian rules are now dead, either from their own hand after suffering concussions or instantly after suffering head knocks on the field.

They were Heather Anderson, Jacinda Barclay, Maggie Varcoe and Elisabeth Memos.

Two of them had brain bleeds (Varcoe and Memos) and the post mortem of the other two (Anderson and Barclay) found they had chronic neuropathological impairments which is significant brain damage.

Sadly, history repeats itself.

To allow Murphy to continue to play arguably sends a wrong message to all levels of football.

That it’s OK if you’ve suffered 10 concussions because the AFL said it was OK.

It can’t be. Every case is different for sure, but when should alarm bells be heard? Oxford University said three.

The AFL’s HIA testing, which is completed for potentially concussed players during a match, also initially failed Murphy.

Post Grand Final last year, Murphy said: “I passed the test, but I ruled myself out. I had a bit of blurry vision, and with my concussions, I kind of get them delayed. I know the concussion test off by heart now … I’ve done that a couple of times now, where I’ve passed it, then we’ve ruled me out.”

Of course he knows it off by heart.

Fingers crossed he doesn’t need another one. If he does, what does Collingwood do then?

I just posted it.

Even if you agree in principle with what Robbo is saying, he has written it in such a way that it's just yet another pre-season critique of the Collingwood Football Club instead of genuine care for a player's wellbeing.

 

[rand corp]

I think what Macrae has going for him is that althought Pendles is tipped to play two and a half thousand games, Mitchell and Sidey will almost certainly begin to drop off sooner rather than later. Mitchell has been fantastic but did have a bit of a dry spell mid-year. Sidey had a fantastic year but can't go on forever, (unlike Pendles). Macrae looks one injury or one reasonable drop in form away from having a real crack at cementing a spot.

And why write an article about Murphy specifically. Could have easily written the same article about Angus Brayshaw or a number of other players.

Correct me if I'm wrong, but didn't Murphy and his family themselves request for Murphy to go through the concussion panel process? Is the article being written because Murphy chose to go through the process himself and other players with a concussion history have not?

 

[Pie thon]

It'll all depend if we use two or three picks, but even then, they may go with 1 defender, 1 forward/ruck and one mid. If they forgo teakle, then it'll be one mid, one key position. Sure they could take 2 mids and one key position; but all of this will depend on how many spots they want to use.
But we have 12 players who can play midfeld, I'd be shocked if we got that many injuries. Take in account lippa too, Beau could play midfield minutes. And we want to get games into fin, and allan. Mattia could play a few mid minutes too.

I think we would be fine with 1 more mid, doesnt need to be two.

Hopefully a good year on the injury front. Brisbane have had good health since 2019. It's doable to have it consecutive years.

Yes I'm wondering why he didn't include other players who also have a history of concussions & are still playing with the blessing of their clubs. Brayshaw & the Dee's was the obvious inclusion imo. Particularly with all the attention they gave that incident last year.

 

[unplugged]

I’ve been a minor buyer of Bytel stock for a couple of years and know he’s been injured a lot, sub at senior level often (when he plays) and dominant at VFL level so those surface numbers didn’t feel right.

I can’t rate Sullivan ahead because it’s purely VFL. The other two I know are capable of playing at the top level in some capacity because they have. Going back though to an earlier post I think people are sleeping on him as a competitor to Macrae.

All this discussion is probably moot though with the move some of us have been calling for going on 12-18 months of McReery up the field (looking at you unplugged). If he can bridge that knowledge gap that sees him going from see ball get ball to knowing the game one or two possessions in advance he’ll be an elite mid. That comes with understanding the system for now though to be a full time mid he needs to be a 15cp player which is a lot because I haven’t seen a strong ability to get “easy” ball. His ability to break that first tackle is going to be fun to watch alongside JDG and Naicos if it clicks. Macrae definitely doesn’t have that.

At this point my man Beau is tracking a little like JHF despite being a year ahead; built like a brick shit house, good pace off a step and strong, but very limited knowledge on how to link up and use teammates to get out of trouble. First instinct is often to fend rather than distribution.

But when it works, it's glorious. The deft kick to Bobby Hills in Q1 of the grand final wasn't a fluke.

Hopeful Port fans (and formerly North fans) were hopeful JHF would become the next Dangerfield but he won't until he grows his game sense. And that's a big IF.

The thing holding back Mccreery the most at the moment is probably lack of opportunity as much as anything, which is a credit to how good we're going. He only had ten centre bounce appearances last year which is lower than Elliott, Lipinski and Sidebottom. That and trying to go flat out and forgetting how to bounce.

Think he's the type of player who'll push in more if we're getting bullied or after a Tom Mitchell gets subbed... or maybe after the game is won... until in time he becomes more reliable and we can turn to him to pull a rabbit out of the hat in search of turning a game on its head.

Absolutely, as the same argument can clearly be made for Brayshaw but not a mention.

For The same reason that he singled out Collingwood in his story on the drug stats a few years back. Click bait and he hates the Pies. i hope Eyre becomes a jet just to piss off Robbo. Bloke is a fraud.

Can someone refresh my memory on the worst couple of these 10 concussions ?

 

[JuniorB]

is this the longest off-season ever? I dont think that i can make it to the start line...

It's actually shorter, because we won the flag, and started preseason a bit later.
I'd be happy to take that every year!

[JuniorB]

It will come up during the season at some point. We used almost every player on our list last year in the seniors.
It's easy to forget, but when we had a couple patches where 5 guys were out. The VFl had their 5 outs too. All in various positions. Thats where Carmichael, Kelly, Bianco and Ryan pop up for their one game. The 30-40 ranked players that helped get us over the line in close ones against the Saints and bombers. I know it's not much. But that consistency keeps the line up stable and more predictable to one another. And I know we have praised the coaching staff on getting the players familiar in other roles. But when you start losing, they will get criticised a lot for it. Like with Beveridge and Bucks in the past.
I'm in the opinion that by the time the mid season draft comes along we will be top 4 and get a low pick and the good mids all gone, so lock them in now.
The collingwood management are on a hot streak, so I'll end up changing my mind to agree with them I the end

I think you're being a bit pessimistic, but we DO need coverage.
And it's better to pick them when we have no competition, rather that hoping our chosen player gets through to our MSD pick.

 

[Back2backJack]

Really only got Ryan Jiath Dean and maybe an Eyre to cover for Murphy and Howe in the future, love to get another top year out of both boys but for different reasons it could end at anytime for either of them.

Murphy is surely at risk, but his own preference should be considered if he is prepared to take that risk.
What was the club supposed to do?
Delist him and have him picked up by another club?
They went before the AFL medical board and were given the green light, so they have followed due process as far as the AFL are concerned.
But according to Slobbo, the club are at fault.

imagine writing a piece on such a critical topic that will (re)-shape the game, where the science is clearly continuing to evolve, with experts still trying to differentiate between correlation & causation, and choosing to make such a definitive & conclusive comment about one (1) specific player ..

"But he shouldn’t be playing footy!!

Of all the summer AFL announcements, the December 20 missive that declared the AFL’s concussion panel had passed Murphy to play in 2024, was the most ASTONISHING."

imagine making a comment about that 1 player when you have no access to his medical history / records, ZERO understanding about the health of that one individual and even less expert know-how about the subject you're being so definitive about ..what an embarrassment, what a w***er!

next time you wanna take the paternal, condescending (dressed up as faux care) tone, why don't you lecture all & sundry, yourself included, on a topic you are eminently qualified to wax lyrical about ...

The micro concussions was CTE specific, which seems to be the glamour child of head trauma. This study was more general and looking at brain function with potential links to dementia in later life. The study actually suggests that just one serious concussion is linked to reduced cognitive ability in later life and more than that increases the risk. 3 milder ones. The assumption is that it then leads to higher rates of dementia.
