Wow the Dogs did get an armchair ride in their Premiership year. 

At least the umps appear to have eased up in the West since the media spoke about the "noise of affirmation "or whatever it was called.

These stats are interesting and the differentials are most annoying in first analysis. Care is given to certain teams and the majority of teams make up their rewards. This has little to do with the even playing field that umpiring should be providing.

It must also be considered that it is not just the number of free kicks that are (nowadays) traditionally awarded and/not awarded in the realm of such 'officiating' care; it is more important to analyse those frees that:

  • make or break the winning of a game for a particular team in 'care' (for example, where and when the free kick was awarded) 
  • and did it/ did it not affect the outcome of the game as a result - ie: assured winners/assured losers
  • or even, force a team to lose a game or to provide 'eveners' between the sides to enhance the 'spectacle' from the AFL points of view?

This is not cynical; this is a feature of our game these days.

West Coast.

Would love to see the Home/Away breakdown.

Those Perth umpires deserve a bullet.

What's probably most interesting is that there was the "freekickhawthorn" hashtag going around but boy the dogs got a incredible run in 2016, and looking at WC who haven't been in negative figures in the last 16 years, though that doesn't surprise me given the times you witness opposition players get their heads taken off with no free kick and yet they'll get the lightest touch on the shoulder (while dropping their knees) and get a free kick every time.

It would be interesting to know the Eagle's differential away from home because it wouldn't surprise me if that's positive as well.

Also the frees that should have been paid but weren't.  Those can have just as great an impact on results and how the game is played.  Imagine how different the game would be today is Scott West was called for throwing the ball.

You are correct. Regretfully, there are still many ways yet to be mentioned for umpires to affect game outcomes. What is good for the goose, ain't necessarily good for the gander.

Yes.  It would be interesting to see the numbers for the individual umpires. 

There are at least 2 who never call anything other than "play on" the whole and every game. 

And  if we knew the numbers for the W.A. based umpires I suspect it would show an even more lop sided number in favour of the home sides.

The mind blowing stat in that table is what in the hell happened with GWS in 2019.

It is an outlier that blows the bell curve wide open.

You would also expect teams to go positive and negative on  a year by year basis. The ones that don't are the ones you need look at. Other than North and West Coast (both positive) and GWS (negative) the rest on  a quick look appear unremarkable.

Free kicks which resulted at a shot on goal would be interesting.

This is why I hate when people say "it will all even out in the end" as an excuse to not use technology to make sure better decisions are made.  Yes, the technology has to be good enough to truly assist, but "evening out in the end" is a statistical anomaly, not a norm.

I believe the AFL assigned experienced non-WA umpires to WC home games a few years ago to stem the clear bias the crowd "BOO!" was causing and their free advantage has moderated.

GWS deliberately played pretty unsociable football this year so it's no surprise their differential was up.  Beveredge was bleating about it after this year's final.  Unsurprisingly he made no comments when the Dogs threw the ball all 2016 and got the greatest armchair ride in that year's GF.

Having said all that, AFL football is extremely difficult to umpire and the abuse umpires get is a total disgrace.  Grand Final umpires are booed when they are announced on gameday!

FFS, I love bagging umpires as much as anyone, but in reality maybe 1 game in 100 is decided in any meaningful way by controversial decisions. It's a bloody hard game to umpire, and good umpiring doesn't equate to a 50/50 split of free kicks. Could it be better? Of course, but umpires aren't on the long list of reasons we haven't won a flag since man first walked on the moon.

I love how these lists provide conclusive proof that the likes of Collingwood get an armchair ride, while we conveniently ignore the fact that the equally feral Essendon and Richmond fans don't seem to influence umpires in their games.

I'll concede the WC trend is clearly fckd though (for those interested, the chances of obtaining a positive free kick differential for 17 consecutive seasons are roughly 7.5 in a million if umpiring is unbiased).

I would hope that that numerical assessment is fact - it truly proves a point if that is the case, let alone the 'general' indication that the longitudinal positive free kick differential over such a long time might assert without deep scrutiny.

Assuming the odds in any one year are one in two of being positive or negative, the odds of 17 years positive are around one in 65,000 (I think)

How bad would have Geelong’s free kick differential been without Duckwood? WC have their well known maggot parasites but their positive differential is Bradmanesque in magnitude and almost 95% better than next best North. Fremantle playing at same ground have one of the worst negative differentials and don’t appear to get any home town favouritism at all so I don’t put too much weight on the crowd effect. Something stinks.

    THE YEAR THE SKY FELL by The Oracle

    After a number of years of linear movement up the ladder, the Melbourne Football Club unexpectedly went into serious decline in 2019, slumping from fourth to 17th in a season that coach Simon Goodwin described “a complete wipe-out”. Those around the club who tried to analyse the apocalyptic events that unfolded during the year were hard pressed to find a single reason for the debacle but the most plausible explanation was that the club’s troubles stemmed from a lack of fitness and injuries that

    BACK IN STYLE by Whispering Jack

    From the moment when the Elton John character in the movie “Rocketman” burst into its opening scene dressed as a flamboyant demon on his way to an addiction rehabilitation session, the game was on. Here was yet another film about a person gifted with a meteoric rise to stardom finding coke, booze and a hedonistic lifestyle that led directly to a destructive crash into the abyss. Ultimately, these stories end in total disaster (“A Star is Born”, “Bohemian Rhapsody”, “Judy”) but this one resulted

    THE TRADING CHRONICLES 2019

    PART ONE - OVERTURE  I have a disclaimer at the outset. I’m not a fan of the races - be they horses or motors of any kind. Once the final siren sounds on the football season, I find the month or so that follows and corresponds roughly with the Spring Racing Carnival to be the most boring time of the year for sports fans. You turn on the radio and you’re confronted by the monotonous drone of a self-proclaimed racing expert or by the nasally twang of an ex-jockey banging on about the equine p

    PART 1 - IT’S A LITTLE MORE COMPLICATED THIS TIME This year’s free agency, trade and draft period will see the usual drama and upheaval as the AFL’s 18 clubs seek to better their lists in order to challenge for finals and possibly premiership honours. Long before the final siren sounded on the season just over a week ago, the maneuvering was under way with player agents and clubs discussing possible player movements and in some cases, deals had already been done.  Yesterday, the r

    HOW FAR SOUTH? by George on the Outer

    It was appropriate that Melbourne was playing its last game of season 2019 in Hobart.  After all, how much further south could the team go? And much as it has done in many of the previous 22 games, the side managed to extract a loss from a winning position by simply giving the ball back to the opposition time and time again. In fact, they gave it back to the opposition to the tune of 53 points from turnovers while, by way of contrast North Melbourne contributed  only 17 points to their oppo

    COOKED by The Oracle

    I can vividly remember when the Demons ventured onto Blundstone Arena for the first time in early 2016 only to lose to the Kangaroos by 20.11.131 to 21.10.136.    Melbourne was then a team on the up and up: young, enthusiastic and bold. It gave up a huge quarter time deficit after kicking against a strong wind but made that up by half time and fell dramatically short after an exciting high scoring affair.  The team lost no fans that day - they were willing to take the game on and attac

    HELP by KC rom Casey

    The Casey Demons finished off their home and away season against Frankston at Skybus Stadium on Sunday with a narrow, unconvincing 6-point victory that left the door slightly open for a top eight berth when the VFL finals begin in a fortnight’s time. While sunny skies prevailed over Frankston in the morning, the skies became overcast by noon and heavy waves pounded the bay nearby as the rains came in to greet the players as the game started. And conditions stayed dark and dreary for the rem

    Thanks, but no thanks! In a round where the club was supposed to thank their fans for the support during the year, the Melbourne Football Club chose to do otherwise with a 53 point loss to a team that sat 15th on the ladder.  Don’t give us cheap jumpers that can’t be sold in the Demon shop.  Don’t give us vouchers to shop there, give us something on the field, which is why we come to the football in the first place.

    SLEEP OUT AT THE MCG by The Oracle

    Around about 12 months ago Melbourne and Sydney fought out an epic battle between two top eight teams fighting for the best possible ladder position in the lead up to the finals. The Swans triumphed by 9 points at the MCG after the Demons came back from five goals down at three quarter time. But for its poor kicking for goal, Melbourne might well have won the game and finished in the top four. Who knows what might then have happened for the club in September?

    We have seen it all before… Yes, a wonderful idea to showcase what used to be in football.  Big crowds, umpires who knew how to apply the rules and not opinions, high marks, skilful players. But for the Melbourne supporters their retro is what it has been like for the past 10 years. Losing games, end on end, year after year.  Opportunities squandered in front of goal. VFL standard players running around at the MCG. Just more of the same, and the game against Collingwood was no ex

    Thanks to Demonlanders for their input into this week’s preview. Ralphius Maximus is short and bittersweet: We'll crack in at the bounce to create a contest, win our share of the ball, butcher the forward movement and get scored on easily from the intercepts. Not that hard to predict. Big Demon says: Unfortunately Collingwood will win because they have a lot more to play for. We will be good in parts but really the season is well over so we will have to put up with those bell
