AFL Power Rankings: Round 10 2019

Without Tom Mitchell, Hawthorn appears to be a decent but middle-of-the-pack side.



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.


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.
