AFL Rankings: Round 14 2024
A few weeks ago, I said that Hawthorn may be better than what many were giving them credit for. This was based on the Hawks having more contested possessions and similar inside 50s to their opponents but falling down in converting forward opportunities to goals. Since then, the Hawks have won six out of seven matches, and only lost their other match in the final seconds. They are fourth for ranking points over their past seven matches, behind only the three current top-ranked sides Sydney, Brisbane, and the Bulldogs, two of whom the Hawks have beaten over that period.
What the Hawks have done better over the past seven weeks is indeed better convert forward entries into goals. Their average inside 50s per game have actually fallen slightly, but they are averaging about four more scoring shots and four more goals (see table above). They are also allowing a few less inside 50s by their opponents per game. With their better conversion rate, the Hawks are now more the standard of side that could play finals, although they still face an uphill battle to make it after their slow start – even if we did rank them more in line with their recent form.
Heave-hoed
Man, did I put the mozz on Fremantle after spotlighting them last week. Their uncontested ‘keepings off’ game style got dismantled by the other team that really likes to handle the ball – the Western Bulldogs – as they were beaten by 67 points, conceded 23 goals, had 69 less uncontested possessions, and 42 less marks. They did still win the clearances though, so there’s that. I’ll take this as a delayed response to spotlighting how good the Western Bulldogs are the week before.

AFL Rankings: Round 13 2024
The
Fremantle Dockers were widely considered to be a slight disappointment last
season. They jumped from eleventh to fifth in the 2022 season with a
young team, and were expected to again play finals in 2023, but instead they
fell back to ten wins and fourteenth spot.
By the
rankings this change was more marginal – the Dockers finished a few spots
higher in 2022 than they were ranked, and dropped just over a goal’s worth in
ranking points in 2023. In 2024 up to about the season’s halfway point, it
looked like they had moved back a bit closer to their 2022 form again, although
given the closeness of teams in the middle of the ladder, not necessarily with
the same lofty result.
That
was until their 92 point demolition of Melbourne in Round 12. That has vaulted
the Dockers up to the league’s second highest percentage and third on the
rankings. Suddenly Fremantle are looking as good as any team not named the
Sydney Swans.
The
Dockers play a very noticeable high possession, uncontested game style. They
lead the league in average handballs per game, and in disposal and kicking
efficiency. Much of this happens in their backline, with Luke Ryan and Jordan
Clark being in the top ten for disposals and marks per game for defenders. This
seems to have been quite successful in preventing opposition scores, with the
Dockers having the second best rebound 50 to opposition inside 50 ratio, and conceding
the fewest points on average this season.
Fremantle is not just relying on retaining possession to get things done though, as they also have the third best contested possession differential in the league – including a massive +42 differential in their most recent win against Melbourne. In particular, the Dockers have been dominant at the stoppages, with an average clearance differential of +9. Amazingly, they almost doubled the clearances of a Demons midfield that included Max Gawn, Clayton Oliver, Christian Petracca, and Jack Viney. Caleb Serong leads the league in average clearances per game this season of players who have played more than seven games, even ahead of noted clearance ‘beasts’ Matt Rowell, Nick Daicos, Marcus Bontempelli, and Patrick Cripps.
That does however mean their ‘post-clearance’ contested possessions are slightly down, and there might be a question of how much they can rely on their ball retention under the ‘pressure cooker’ of finals. Further, the Dockers have beaten no team in the top eight – although they came close to winning three of those matches. Good signs are there for Fremantle though, and a performance like their most recent one more often than not is indicative of a team headed towards the upper end.

AFL Rankings: Round 12 2024
The
Western Bulldogs are considered by many to be one of the most ‘talented’ teams
in the AFL. That perception might be partly due to having arguably the league’s
best player Marcus Bontempelli, partly due to having a strong midfield, and
partly due to having multiple young, tall talented forwards – more so than they
actually have a ‘stacked’ playing list.
Nevertheless,
when the Dogs lost to Hawthorn and were three wins from eight matches,
commentators were starting to frame the coaching obituary of Luke Beveridge.
There were perceptions that Beveridge had lost the playing group, and
potentially ‘lost the plot’, with unusual moves such as subbing or dropping
former All-Australians Jack Macrae, Caleb Daniel, and Bailey Dale, as well as
highly touted rookie Ryley Sanders.
Since
then, the Bulldogs have won three out of four matches, losing only to
top-placed Sydney in a match where they had six more scoring shots. The Dogs
may currently sit outside of the top eight on the AFL ladder, but they have
been fairly strong overall, with basically the league’s second best percentage (with
Fremantle) behind the Swans. Some inaccuracy in front of goal possibly cost
them a couple of wins, losing both to Sydney and Essendon despite having more
scoring shots.
The
Bulldogs are also performing well in some key areas, which suggest they might
be able to sustain their high points differential. They are currently first for
disposal differential, second for inside 50 differential, second for clearance
differential, and sixth for contested possession differential. To be sure, big
wins against Richmond and West Coast helped boost their percentage and other
differentials, but the Dogs’ overall profile is still that of a team placed
higher than they currently are.
A major reason for this is again of course Marcus Bontempelli, who is performing just as well if not better than last year. The Bont is currently the league’s highest-rated player this season who has played more than two games (according to AFL Player Ratings), once again ranking high in contested possessions, inside 50s, and score involvements. Injuries to his main ‘offsider’ Tom Liberatore have hurt, but his production has been ably filled by Adam Treloar, who is getting about as many possessions and more inside 50s than he ever has.
A long-term injury to Aaron Naughton, who had been the league’s highest-rated key forward, may decrease their ability to kick goals over the next several weeks, not helped by a two-match suspension to their next best forward Sam Darcy. Win the next two at home against Brisbane and Fremantle though, and the Bulldogs might find themselves in a decent position going into the home stretch.

AFL Rankings: Round 9 2024
Essendon
are ‘defying’ the rankings so far this season, currently sitting third on the
AFL ladder – albeit a draw away from seventh – while still being only ranked
fourteenth. Why the large discrepancy?
First,
Essendon have a very low percentage for a third-placed team. Three of their
wins were by a goal or less, and their two losses were by almost 100 points
combined.
Second,
Essendon had a terrible end to 2023. They lost three matches by 70 points or
more, and they beat West Coast and North Melbourne by a combined 10 points. Their
average net margin adjusted for estimated home ground advantage and opponent
strength was -45 points over their last seven games (see chart below). That is
still one-third of the games included in the Bombers’ current ranking.
Not having much of an effect is the fixture. Essendon do have a couple of easy games coming up, but so far in 2024 they have played a mix of strong, average, and weaker teams.
Are the rankings placing too much weight on the Bombers’ poor end to 2023? Possibly. In 2024, they have a slight position average adjusted net margin, which would place them around the middle of the pack for teams – about where they would sit if the Magpies had scored one more point on Anzac Day. They were around average for a fair chunk of 2023, before falling away at the end. That seems about where they are at, and around where the rankings – with some valuable wins already in the bank – have them eventually finishing this year.

AFL Rankings: Round 8 2024
Richmond
are last for free kick differential (free kicks for less free kicks against) so
far in 2024. They were second-last (per game) in 2023. They were last in 2021
and 2022, second last in 2020, and last in 2017 and 2018. How does it keep
happening?
One theory
was the game style that the Tigers played under coach Damien Hardwick, or at
least the style they played during their golden era from 2017. However,
Hardwick left as coach part way through last year. His new team the Gold Coast
Suns are third for free kick differential. And under new coach Adem Yze
Richmond are not a high-pressure team, ranking last for tackles and low for pressure
acts. Perhaps it’s more to do with the players?
Richmond
are losing the free kick count in most areas of the ground (see table below),
although the two areas where they are most significantly doing so are for Midfielders
and Key Defenders. For Midfielders, it’s their wings Kamdyn McIntosh and
Marlion Pickett that have the largest negative differentials. For Key
Defenders, it’s Dylan Grimes – who has had an even free kick differential for
most of his career – and inexperienced talls Ben Miller and Tylar Young. Ruck
Toby Nankervis also continues to be a main ‘offender’. But Nank aside (and
Grimes, but he’s only a recent ‘offender’), that’s hardly the ‘spine’ of the
modern Richmond era. Shai Bolton used to have a heavy negative differential too
that contributed to past results, but has improved over the past two years.
So the negative Richmond free kick differential has persisted through changes in coach and players. Maybe the Tigers just keep finding ‘undisciplined’ players? Maybe it’s a game style that has persisted after Hardwick? Or – as much as this blog tries to find evidence that isn’t ‘conspiratorial’ … maybe this trend has reached a point to conclude that Richmond could be umpired a bit differently?
All that said, the free kick differential probably isn’t hurting Richmond a huge amount (other than supporters’ mental health), just as it did not stop them from winning premierships in 2017, 2019 and 2020. A contested possession is estimated by Champion Data to be worth about a point, so on that basis the Tigers’ free kick differential is costing them perhaps about a goal per game in points differential, although possibly a bit more if their defenders are more often getting pinned. That might cost them a win or two in a year where they are lacking them – although the ‘silver lining’ is it might also give them a higher draft pick…
