AFL Rankings: Finals 2024
The
Brisbane Lions are the premiers for 2024, and in some ways they had to ‘defy
history’ and in other ways not so much. The Lions had to win the flag from
fifth, meaning they had to win four games in a row, with two of those involving
travelling to play their opponent in their home state. They also had to come
back twice from difficult positions in the third quarter, from 44 points down against
GWS, and from 25 points down against Geelong. Their 60 point win against Sydney
in the Grand Final may have covered over in many people’s minds how close the
Lions were to being eliminated in the second week.
To add
to that, Brisbane had to face an uphill battle within the season just to make
the finals in the first place. They began the season with two wins from their
first seven matches, and had just four wins and a draw by their mid-season bye.
The Lions then won ten out of their last 12 games to make the finals, but still
missed out on a top four spot and the ‘double chance’.
On the
other hand, the indicators were there that the Lions were always among the
better teams this season, even when they were losing early games. At Round 7
they had a scoring shot differential of +2 per game, and an inside 50
differential of +10, indicating that they were generally doing well across the
field other than converting territory to points. By the end of the season,
their inside 50 differential had dropped slightly to +9 per game – still good
for second in the league – but their scoring shot differential had improved to
+6, and their points differential to +19. It wasn’t dominant, but it was good
enough to be among the top contenders this year.
The Lions were also a pretty well-rounded side. They ranked first in contested possession differential this season, including second in clearance differential. But they could control possession as well, ranking sixth in uncontested possession differential. Against GWS and Geelong they were slightly behind on contested possessions, but well ahead on possessions overall. Against Sydney they were almost even on contested possessions and inside 50s, but controlled the ball to great effect, with almost 80 more uncontested possessions.
Like Collingwood last year, Brisbane’s premiership wasn’t so much a reward for being clearly the best team as it was for continuing to put yourself among the top contenders to win. They’re currently not a clear favourite to go back-to-back next season, but the probability is high they’ll be up there again, and they may be able to grab their chance at glory a second time.

AFL Rankings: Round 24 2024
In
most years since the AFL has had an eight-team finals series, the premiership
winner has come from the top three. In part this is because the top four teams
must win only three games rather than four games to win the premiership, often
with home ground advantage. Also, they are usually the best or most in-form
teams.
This
year however, the rankings have the best teams in the finals as coming from
outside the top four. Hawthorn, the Western Bulldogs, and Brisbane are the
three highest-ranked teams. Collectively since Round 11 they have won 29 out of
36 games. But due to their low wins in the first half of the season, they have
finished fifth, sixth, and seventh on the ladder.
In a
straight head-to-head matchup, the rankings currently favour Hawthorn in any
final. If they played minor premier the Sydney Swans in the Grand Final, which
is played at the Hawks’ home ground the MCG, the rankings would pick them by 22
points with a 73 per cent win probability.
The
Hawks however are trying to win the premiership from seventh, which means
winning four games in a row. Also, their first match is against the
second-ranked team the Western Bulldogs, for which they have a 57 per cent win
probability. That makes a Hawks’ flag still a relatively long shot.
It is rare for a team to have more than an estimated 40 per cent chance to win the premiership at the start of the finals, and they certainly don’t this year. The teams with the best chance though may still be the top two teams on the ladder, Sydney and Port Adelaide. They start with ‘home’ finals which they are favoured to win – although Sydney, playing fellow New South Wales side GWS, will not have the home ground advantage that Port will – and with a first-week win would then have another home final to qualify for the Grand Final. On current rankings they wouldn’t be favoured in the Grand Final against Hawthorn, the Western Bulldogs, and Brisbane, but they certainly won’t have to play at least one of the Hawks or Dogs, and they have a decent shot of the other two teams being knocked out before they can get there.
Even still, there is a good chance that the premiership winner is not one of those two teams. Unless a team suddenly hits dominant form, this looks to be one of the most evenly matched AFL final eight series ever.

AFL Rankings: Round 23 2024
Did Essendon actually get found out?
Essendon will now miss the finals in 2024, after
sitting in second halfway through the season, and after still being in the top
four just six weeks ago. The two most common narratives to explain this fall
are: a) Essendon played easy teams earlier in the season and got ‘found out’ as
they played harder teams, and b) Essendon drop away as the season goes on. There
is a bit of truth to both of these things, but even relatively simple analysis
shows there is more to it than that.
On the first point, Essendon’s fixture did get
tougher towards the back end of the season. They had a nice little stretch in
the middle of the season when they played bottom teams Richmond, North
Melbourne, and West Coast twice (see chart below). After that, their fixture
did become tougher, although not hugely so. Their early season run looks tough
in hindsight, but they did play Hawthorn and the Bulldogs before both of those
teams hit their current hot form.
On the second point, Essendon certainly fell away
badly towards the end of last season, with some big losses. My rankings had
them lowly rated as a result, and it would be tempting to see their recent
results as a reversion to this level.
The Bombers though are possibly a bit better than
their results suggest. They are one of the leading teams for inside 50 differential
this season, which indicates that they are at least putting themselves in a
good position to outscore their opponents. They have however struggled to
convert their forward opportunities relative to other teams, with about the
same number of scoring shots from over five more inside 50s per game (see table
below). That they have maintained their inside 50 differential as their fixture
has become harder suggests they may have even improved in this area as the
season has progressed.
What has turned against the Bombers though is their opponents’ accuracy in front of goal. Since the halfway mark of the season, Essendon’s opponents have averaged around the same number of scoring shots, but two more goals, converting shots to goals at a rate well above the league average. It could be argued then this has been a bit ‘unlucky’ for the Bombers.
Essendon were probably never a ‘top four’ team this season, at least not unless they converted their forward opportunities better. But there may be more cause for optimism about how they finished this season compared with last season, even if the resultant fall in ladder position seems more dramatic.

AFL Rankings: Round 22 2024
A few weeks ago, I tried to make some sort of sense of the large set of teams occupying the middle part of the AFL ladder, and where they ‘really’ stood in relation to each other. Things have shifted a bit since then, particularly in cases where the final result was unexpected – where do they stand now?
One of the most significant changes has been the drop-off in Carlton’s
performances, and their
chances of finishing in the top four, or even playing finals at all (see table
above). A few weeks ago I said they would start favourites in all of their
remaining matches, but they have ended up losing three out of the next four.
They still have a couple of relatively friendly match-ups to finish off the
year, but so do their nearest rivals for finals spots in Hawthorn and the
Western Bulldogs, and winning both games may not be enough.
In the other direction, Port Adelaide has performed better than expected, beating Carlton and demolishing ladder
leaders Sydney by an astonishing 112 points. They have a couple of tricky
matches remaining with the Showdown against Adelaide and an away match against
Fremantle, but at worst they are almost certain to finish in the top eight now,
and they are a very good chance to finish in the top four.
Four results were key on the weekend in terms of
involving multiple finals contenders – Sydney beating Collingwood, Geelong beating
Fremantle, GWS beating Brisbane, and Hawthorn beating Carlton. This has left Sydney,
Port, Geelong, GWS, and Brisbane as the teams most strongly contending for the
top four, and Fremantle, the Western Bulldogs, Hawthorn and Carlton as the
teams most strongly contending for the remaining spots in the top eight.
The Brisbane-GWS result in particular had a major impact. The Lions are still considered by the rankings points to be the best team, and they looked like it in the first quarter in the Giants with over 20 more contested possessions, and ten more scoring shots. But their problem from the early season of inaccuracy in front of goal, couple with their bad luck in their opponents being accurate, came back to plague them – the Lions had ten more scoring shots and yet lost by 18 points. This puts them now half a win behind the top four, and relying on at least one other team to lose to finish there while not ‘slipping up’ again themselves. GWS meanwhile are now a very good chance to finish in the top four themselves, even with a couple of tricky match-ups to finish off.
It's not overstating things this year to say that the next two weeks’ worth of results will be crucial, particularly with in-form teams Hawthorn and the Western Bulldogs lurking in the lower half of the eight. Teams may feel more confident than usual that they can win the premiership from fifth or lower, but home ground advantage and a double chance are still going to significantly improve your prospects of a successful finals run.

AFL Rankings: Round 19 2024
After two
straight losses, Carlton had a hard-fought win against North Melbourne on the
weekend, keeping them in second on the ladder. Nevertheless, some of the flaws
in Carlton’s premiership credentials have become more apparent over the past
few weeks.
Carlton
has conceded the fifth-most points of any team this season, whereas teams that
win the premiership are generally stingy in defence. The Blues can at least
score a heap of points themselves, ranking second for points for – Carlton games
have so far been on average the biggest ‘shootouts’ this season.
This high leaking of points stems from the Blues having trouble stopping opponents when they get the ball. Carlton has the best contested possession differential of any team this year (see table below). Yet their inside 50 differential is negative, which is highly unusual for a team sitting in second. GWS and the Bulldogs easily beat them in this area in the Blues’ two losses, and even North beat them here on the weekend. They are pretty good at stopping the ball once it gets in their back 50, but overall it means they are in the bottom half of teams in conceding scoring shots per opposition contested possession.
Teams usually do not give up points as easily as Carlton are doing and win the flag. The Blues could end up making up for this by just piling on the points themselves – after all, they just need to score more points than their opponents. It is just going to be harder for them to keep outscoring their opposition if they cannot clamp down on them a bit more.
