AFL Power Rankings: Round 13 2019
If my rankings' predictions were being used on Squiggle, I'd be at the top of the leaderboard. Just saying guys. :)
(Of course, if they were near the bottom, I'd be dead quiet about that...)

AFL Power Rankings: Round 12 2019
Nothing will ever diminish the West Coast
Eagles’ 2018 premiership triumph, but they are far from the most fearsome
‘reigning premier’ we have had.
The reigning premier is
clearly not the best team so far
The title of ‘reigning premier’ deservedly carries a lot of weight. Like a boxing heavyweight champion, the team that won the premiership last season is often season as the ‘team to beat’, up until the point that they are eliminated from the current season’s finals race.
In 2019 the title of reigning premier belongs to the West Coast Eagles. Halfway through the season the Eagles are hardly looking like the fearsome ‘team to beat’. They sit fourth, with eight wins out of 12 matches, three wins behind pace-setters Geelong.
More worryingly, they have a percentage of only 103.0. The Eagles have been well-beaten three times this season by teams that are merely around average: by Brisbane in the opening round by 44 points, by Port Adelaide at home by 58 points, and this weekend by Sydney by 45 points. (They were also beaten by Geelong by 42 points.)
West Coast’s average net margin this season, adjusted for estimated home ground advantage and opponent strength, is only +3 points (see chart below). Clearly, the Eagles to date in 2019 are not the most dominant reigning champion we’ve had.

West Coast’s average net margin this season, adjusted for estimated home ground advantage and opponent strength, is only +3 points (see chart below). Clearly, the Eagles to date in 2019 are not the most dominant reigning champion we’ve had.
The Eagles were not a dominant premiership team
A premiership is a premiership, and always deserved. West Coast was fantastic in last year’s finals series, with an average adjusted margin of +37 points (see chart above). The Eagles beat Collingwood twice – including once at the MCG – and destroyed Melbourne in the preliminary final. When fully fit, they may have been the best team for the year.
As far as premiership teams go, the 2018 Eagles were hardly the most dominant (see table below). They were probably similar to the 2017 Tigers, and slightly better than the 2016 Bulldogs. According to the rankings however, every other premiership team this decade was considerably better.
Further,
last year’s West Coast team may not have even been the strongest Eagles team
this decade (see table below). I’d say that was the 2015 Grand Final team, that
had a percentage (after finals) of 142.8, but who ran into the
triple-premiership winning Hawthorn side. Arguably the 2011 and 2012 sides were
about as good as last year’s premiership team as well – their ranking points
and percentages were similar.
The 2018 Eagles team benefitted from not having a ‘great’ opponent, or even too many ‘very good’ sides, in its way. (Richmond was possibly great early in the season, but had fallen off somewhat by the finals series.)
The low-rated midfield
Champion Data somewhat controversially rated West Coast’s playing list as only the eleventh strongest heading into the season, and its midfield way down in fifteenth. That may seem laughable to some who saw Luke Shuey and Dom Sheed tearing it up on Grand Final day.
As highlighted by HPN a few weeks back though, the Eagles are pretty low down in terms of their inside 50 differential with their opponents this season (currently fifteenth). They also rank low in differentials for disposals (sixteenth), and centre clearances (last). They’re not exactly lighting it up on the main midfield indicators.
Champion Data rated Luke Shuey, Elliot Yeo, and Andrew Gaff as above average midfielders. However, it rated Dom Sheed, Mark Hutchings and Chris Masten as below average (that rating may have changed for Sheed this season). In other words, Champion Data rated the Eagles as having little midfield depth, and no player among the very best midfielders – not even Gaff, who gets a lot of possessions, but who also has a low average number of metres gained per disposal for a wingman. (Shuey, last year’s Norm Smith Medallist, was of course ‘elite’ on the day that mattered most.)
West Coast is still a good side. After each of their three premierships the Eagles have been a finals side the next season, but not a huge premiership threat. This year – on their form – doesn’t look like changing that pattern.

AFL Power Rankings: Round 11 2019
Fremantle is the most improved team this
season, having once again become a hard team to score against.
Based on
each team’s change in ranking points so far in 2019, the Fremantle Dockers are
the most improved team this season (see table below). Their ranking points have
improved by about four goals, and they have gone from being considered one of
the worst teams to around average. Excluding Carlton and Gold Coast – both of
whom had hardly anywhere to go but up – no other team has improved by more than
seven rankings points this season, not even Brisbane (the big improvers on the
ladder).
Fremantle
has been better than average this season though. Their current ranking is
dragged down by having an average net margin, adjusted for estimated home
ground advantage and opponent strength, of -28 points over the second half of
2018 (see chart below). In the first half of 2019, it is +8 points.
The
Dockers’ rise in ranking however has largely been driven by their performances
in three of those 11 matches. They are: their opening round smashing of North
Melbourne, and their impressive wins away against top teams GWS and Collingwood.
Outside of those three matches the Dockers have been slightly below average (which
is still a large improvement on last season’s performances)
After generally
leaking goals since their 2015 Grand Final appearance Fremantle has once again
become a hard team to score against, having conceded the second-least points
this season. The Dockers are conceding on average 70 points a game, way down
from 93 points a game in 2018.
This
is despite none of their defenders being particularly
highly rated or ranking particularly highly in any category, apart from
Luke Ryan and his ability to intercept. Collectively though, while players such
as Alex Pearce barely impact the stats sheet, Fremantle has conceded the least
marks inside 50 and the least goal assists.
I still wouldn’t be racing
to put money on the Dockers to finish highly (if I raced to put money on anything at all). They are looking a lot closer to
it though than I would have thought at the start of the season.

AFL Power Rankings: Round 10 2019
The Hawks haven't been quite as good this year
Hawthorn – the most successful team of the 2010s – finished fourth on the ladder last year after the home and away season, though there were probably a couple of teams below the Hawks that were better. This year one could have predicted the Hawks to finish anywhere from fourth to twelfth, and probably got a fair amount of agreement either way. Where is Hawthorn actually at?
Hawthorn did finish off last year’s home and away season well, winning ten of their last twelve matches. Even accounting for some weak opposition, the Hawks’ results were pretty good (see chart below). Their finals series was not good though, with Richmond and Melbourne eliminating them fairly comfortably.

Their finals series was not good though, with Richmond and Melbourne eliminating them fairly comfortably.
This year, the Hawks have been slightly above average, and sit about in the middle of both the ladder and the rankings. They’ve had some impressive wins against Adelaide away, GWS, and Port Adelaide (the latter over this past weekend). They’ve also had some bad losses against the Bulldogs and St. Kilda, and a narrow win against Carlton.
Missing Tom Mitchell
In 2018 Brownlow Medal-winning midfielder Tom Mitchell set a season record for disposals, and also recorded the second-highest ever number of clearances. Unfortunately Mitchell will miss the entire 2019 season with a broken leg. How much are the Hawks missing Mitchell?
Quite a bit. No one player is going to significantly make or break a football side of twenty-two players. Hawthorn is down a bit though in some of the main statistics that rely heavily on midfield performance (see table below). The Hawks rank last this year in clearance differential with their opponents, and are no longer among the top teams for inside 50 differential as they were last year.
Some
of Mitchell’s production has been picked up others, in particular Jaegar
O’Meara and James Worpel. It’s tough though to completely replace Mitchell’s 35
disposals, eight clearances, and five inside 50s per game, and the increases in
output from O’Meara and Worpel compared to last season haven’t done it. Both
are doing more, but neither would be considered among the best ‘inside’
midfielders. Ricky Henderson’s improvement – at over 30 years of age – has been
more significant, but while he replaces some of Mitchell’s work in terms of
gaining possessions and metres, he doesn’t replace Mitchell’s work in contests.
The Hawks may still finish as a top six side, particularly if they play like they did against Port. Or they may still finish twelfth. As impressive as they’ve been at times though, they’re probably not challenging for a premiership until they at least see the return of their star midfielder, and more besides.

AFL Power Rankings: Round 8 2019
Through the first third of the season, the
good teams seem to be Geelong, Collingwood, maybe GWS … and not much else.
We are
eight rounds – or one-third of the way – into the 2019 season, and each team
has played almost half the competition. We should therefore have a fair idea
who is playing well this year and who is not.
Nevertheless, some teams
have had significantly easier fixtures than others so far (see table below).
Therefore, there are a few things about the current ladder where the rankings
agree and others where the rankings think the ladder is misleading us a little.
Geelong, who is one win clear
on top of the ladder, has been clearly the most impressive team in 2019 to
date. Not only do the Cats have the highest average net margin, they have done
it with the hardest fixture. Among Geelong’s opponents have been Collingwood,
GWS, Essendon, Adelaide, West Coast, and Hawthorn, giving the Cats an eight
point disadvantage per game compared to an average fixture. Adjusting for estimated
opponent strength (and home ground advantage) gives Geelong an average net
margin of +38 per game, which is right
up there with many premiership teams.
Collingwood sits
second on both the ladder and the rankings. The rankings do not think the
Magpies are a great side yet, but at least they’re good, which makes them the
Cats’ main challengers almost by default. Their fixture is rated as having been
about average so far (although they have struggled to beat their weaker
opponents such as Carlton), suggesting that where they currently sit is a
reasonable indication of where they are at.
Adelaide and GWS sit third and fourth on the ladder,
with the same number of wins and similar percentages. The rankings though think
the Giants are the more impressive team, having had the harder fixture. GWS has
played Geelong and West Coast away, Richmond, Essendon, and Hawthorn. Adelaide
has played Geelong and Hawthorn, but otherwise Port Adelaide has probably been
its only decent opponent.
There
are ten sides that have between three and five wins, and which the rankings
think have performed fairly similarly. Their average adjusted net margins in
2019 have been between about plus one goal and minus one goal per match. Essendon is considered to have had a
relatively tough fixture so far, having played the top three ranked sides, and
therefore it may potentially be better than their ladder position suggests
(though the Bombers’ loss on the weekend to Sydney was hardly impressive). The Western Bulldogs, in contrast, have had
a relatively easy fixture, having played (and lost to) both Gold Coast and
Carlton.
Finally, there are five
teams that the ladder and the rankings both rate as having by far the worst
seasons. These are: Gold Coast,
Melbourne, Sydney, North Melbourne, and Carlton. All of these teams have a
percentage of 85 or under; no other team has a percentage of less than 93. The
rankings still rate Melbourne, Sydney, and North Melbourne as not too bad
overall, because of their 2018 performances. On 2019 form alone though they are
a long way back from the rest of the pack.

AFL Power Rankings: Round 7 2019
Adelaide or Port Adelaide –
who is the better South Australian team heading into next round’s Showdown?
Both are rated just above
average
Both Adelaide
and Port Adelaide are around the middle of the rankings, and rated slightly
above average. Adelaide currently has a few more ranking points – 7.2 points
compared to 3.9 points.
Both have performed
slightly above average so far in 2019. Adelaide’s average net margin adjusted
for estimated home ground advantage and opponent strength is +4 (see chart
below). Port Adelaide’s is a bit higher, at +8, boosted by its big win against
reigning premiers West Coast in Perth.
Both
have been among the most consistently ‘average’ teams over their past 22
matches. Port has had only five matches out of their past 22 where its adjusted
net margin is either greater than 25 points or less than -25 points – the least
of any side (see chart below). Adelaide has had the second least, with seven matches in those categories.
Adelaide: not yet back to 2017
levels
Adelaide
was the
best team for most of 2017, and very
good in 2016 as well, but injuries
hit the Crows hard last season. With more of their top
players available they were a semi-popular pick to shoot back up the ladder
this year.
The
Crows are fairly well-placed so far in 2019, with four wins and three losses.
They have been somewhat helped by a friendly fixture though, beating Sydney,
St. Kilda, Fremantle, and Gold Coast. They lost at home to Hawthorn, and to a
North Melbourne team that has dropped in standing.
Champion
Data rated Adelaide’s list highly coming into the season: rating
it second overall, and strong in attack, the midfield, and defence. That rating
could be seen as a hangover from the 2017 season, with forwards Taylor Walker
and Eddie Betts arguably past their peak. Injuries have also hit the Crows
again – though nowhere near the extent of last season – with the team losing
wing Paul Seedsman, and defender Tom Doedee.
Adelaide
seems to have most of its midfield back and firing, but not quite to the same
effect as the peak days of 2016-17. That 2017 team ranked highly in terms of
contested possessions, clearances, and inside 50s. This year’s team ranks
highly in disposals, but not in those other statistics. Instead, it’s the
Crows’ cross-town rivals that seem to so far have taken their place among the
top midfields.
Port Adelaide: the resurgence
of Travis Boak
At the
end of Round 7, Port Adelaide leads the league in contested possessions,
clearances, and inside 50s, and is third in disposals. Ex-captain and two-time
All-Australian Travis Boak has returned to the midfield, and is in probably the
best form of his career. Boak ranks sixth for contested possessions per game in
2019, ninth in clearances, tenth in inside 50s, and fifth in disposals. Boak’s
resurgence, and that of Tom Rockliff, has helped the Power more than overcome
the loss of Chad Wingard and Jared Polec to other clubs.
Not
that the Power have significantly set the world on fire yet either, despite
their four wins. As mentioned above, their best win for the season was easily
beating West Coast in Perth. They also easily beat last year’s preliminary
finalists Melbourne, but it’s
not as impressive beating the Demons in 2019. Port beat Carlton and
North Melbourne at home by relatively small margins, and lost to a depleted
Richmond.
Port’s
defence – which was one of
the stingiest in 2018 – has been merely average so far this season.
Dougal Howard has performed well, but Tom Jonas had probably a career-best
season last year, and he has dropped off a bit (and been injured).
The
Power also haven’t been able to score efficiently from their weight of inside
50s, with Charlie Dixon out, Justin Westhoff not upping his points total as a
more permanent forward, and star Robbie Gray having possibly his worst season to
date in terms of effectively disposing of the ball. On the bright side,
Robbie’s namesake Sam Gray has found some form. (Port’s also been a goldmine
for fantasy football teams, with first-year players Zak Butters, Willem Drew,
Xavier Duursma, Connor Rozee being permanent fixtures in the line-up. I had
them all.)
Who has the better outlook
this year?
Other
systems, on average, seem to think Port’s
outlook is slightly better, and rate them slightly higher – see, for
example, Matter
of Stats and The Arc. That
could be because other systems adjust to the new season a little quicker than
mine, and/or because Port’s scoring shot differential is better.
I like
Adelaide’s a little better, even before Port
recently got hit by injuries. I think they’re a bit deeper, and have been a
bit more consistent in their performances.
The rankings are tipping Adelaide
by 3 points. Hopefully this week’s game is at great as the two Showdowns last
year.
