A Melbourne mathematician has crunched more than two decades of data to reveal which clubs are the darlings of AFL umpires, detailing the truth behind every side’s free kick count. SEE WHERE YOUR CLUB RANKS.

Everyone hates Collingwood, except the umpires.
Two decades of data crunched by a Melbourne mathematician reveals the Pies, West Coast Eagles and Western Bulldogs are the darlings of the men in green.

And the revamped Adelaide Oval is fast emerging as another whistleblower paradise for Don Pyke’s Adelaide Crows.

Nathan Buckley’s troops have ranked 1st, 1st, 2nd, 3rd and 3rd for free kicks paid to advantage across the past five years.

Curiously, even when on the road Collingwood sit in the top three for free kicks awarded in away games in 13 of the last 23 AFL seasons.

“That’s a dream run,” researcher John Marinopoulos declared in his report compiled for the Herald Sun.


NED-155-AFL-free-kick-count - 0


Marinopoulos, a mathematics and statistics guru from Value Advisory Partners, has analysed every free kick paid by AFL umpires in home-and-away matches since Round 1, 1997 when Port Adelaide joined the competition.

The report shows the powerhouse Eagles have been on the right side of the free kick ledger while playing home matches at Subiaco or the new Perth Stadium in all but one of the last 23 seasons.

They have ranked a runaway 1st for home free kicks in nine of the past 15 seasons.

Sacked St Kilda coach Alan Richardson once famously referred to the favourable run of umpiring enjoyed by the Eagles while playing in front of an adoring home Perth crowd as the “noise of affirmation”.

Since 2012 alone, West Coast has averaged five more free kicks at home than their opposition, despite an abnormally poor run this year.

After shifting to its new home ground in 2014, Adelaide has ranked near the top of the free kick tree in five out of the past six seasons.

The report proves Richardson’s theory: more free kicks have been paid to teams playing at home across every AFL season since 1997.

“There is no doubt over many seasons that there are always more frees paid at home than against,” Marinopoulos said.

“The impact of the home fans is substantial.”

On the flip side, Greater Western Sydney and St Kilda have endured the worst run for total free kicks paid.

The Giants have ranked 17th, 16th, 17th, 17th, 10th, 16th and 15th since their second season in 2013.

“Maybe it’s their style of play or the lack of crowds, but it’s very low,” Marinopoulos said.

The Saints ranked 1st in their Grand Final year of 2009 but have continuously featured at the bottom of the free kick ladder ever since.

Marinopoulos said the Bulldogs and their modest fan base were the league’s anomaly, rivalling the Eagles for free kicks paid at home.

The Dogs have ranked in the top three for 13 of the past 23 seasons in home frees and sit first while playing at Marvel Stadium this year.

They were also No.1 on the free kick register when they broke their 62-year premiership drought in 2016 and sit second overall for total frees since 1997.

For all home-and-away games this year, Collingwood has again enjoyed the most favorable free kick run. The bottom of the pile in 2019 are Richmond at home, St Kilda away, and the two Sydney teams overall.

The data reveals only three teams have bucked the trend and won a premiership in a season when they were ranked last for free kicks: Sydney in 2005, Hawthorn in 2008 and Richmond two years ago.

The report does not include AFL finals matches.

My family friend and ex boss wrote this. Sent me all the data and graphs last week and just proves what we already knew.

Bright guy is John.
 
Interesting to see the Eagles have the advantage at home by miles, yet the Lions and Swans are right down the bottom for free kicks at home. Normally in any sport the home team tends to have a favorable run with umpires. Curious to know why Eagles and Lions/Swans are so far apart. Eagles stadium and fans louder?

We need to get louder and more aggrieved at games - like the Scumwood fans do. We are too passive. We get stiffed by the umpiring most of the time and too many people sit there like stunned mullets.
Oath!

Like the final against the scats
 
Did he have access to data we don’t get as fans from CD? Or just standard free kick data we all have access too?

i believe he had extra data we may dont have, ill have to confirm that though
 
The headline, and what will draw clicks/readers to this article, is the thing about individual clubs being favoured. But the damning thing for me, which reveals that the "noise of affirmation" is a thing, is the fact that all but two teams have a better than 100% score at home and all but three have a worse than 100% away. Simply looking at the free kick differential for an individual club is complicated by the counter-argument that there might be something in the game style of the club that attracts more frees for or against (this is the argument currently made in response to Richmond complaints about our free kick differential). What is clear from these stats is that there is a home bias in free kicks which can't be explained away by game style because it is nearly universal.To the extent that there is a difference between clubs it is a question of how big that home advantage is and that, significantly, seems to correlate with the noise making capacity of their supporter base. In other words, it is confirmation of the "noise of affirmation", just not exclusively for West Coast, though they nevertheless head the table. Poor old GWS.
 
At home we are easily the worst off for frees. But away we do OK. :think:

There is something about the tigers that is weird. I don't see what we do that causes us to be offensive to the umpires.

And the Pies are loved 🤮

WC I understand - rabid home crowd a full continent away
 
Umpire bias in free kicks against us! I knew it!
AFL just customizing the game to their preferred way with subtle engineering by their lickspittles, men in white!
Call it for what it is...cheating! Like Tanking is! The draw is! Marquee games set in concrete!
 
Gameplan has to come into it somewhere. Eagles don't give away many free kicks because we don't tackle. And our dominance in the air means the opposition always give away free kicks in the marking contest.

The true question is why the eagles are now ranked 13th for frees when nothing has changed. Umps clearly have an agenda when they come over now. And its not to officiate the game. It is the keep the free kicks as even as possible.

got nothing to do with gameplan

case in point is the pies completely copying our 2017 gameplan last year and them dominating free kicks while we were clearly at the bottom

What a load of crap, all it's come down to is, the umpires have stopped paying the eagles those soft as butter frees the opposition never got.
 
There's research suggesting it's the dark jumpers.
Long-term trends show Essendon and StKilda are similarly hard done by.

Power (Dis)Play? Teams In Black Draw More Penalties
Hockey teams wearing darker-colored jerseys are more likely to be penalized for aggressive fouls than teams wearing white jerseys, according to new research. Teams wearing black jerseys in particular get penalized the most, according to an analysis that may offer a window into the hidden psychological dynamics of the ongoing NHL playoffs.
"Teams that wore black jerseys were penalized more, significantly more, than teams wearing other colored jerseys," said researcher Gregory Webster of the University of Florida, Gainesville.
