AFL Prediction & Analysis

Collingwood under Buckley

As part of its weekly wrap-up, Footy Maths has a neat graphic depiction of the slide of the Pies under Nathan Buckley, and a measured take on what it means:

Both arrays of data show a decline since 2012. Collingwood has yet to become a sub-average rated team by the FMI measures, which is a limited positive.

Also, when compared to the Essendon journey since Sheedy, the decline has not been dramatic enough to have been sub-par as the Dons were three times before sanctions were levied. But also, after each dive there was a rally and development. The above chart has much less rallying, and more flatlining.

Sydney’s path to the finals may be the weirdest ever

The Arc on the fall and rise of Sydney in 2017.  The Swans are one thing the models got right this year: they never looked that bad, even at 0-6.

No team has ever made the finals after losing their first four games of the season, at least not in the period since 1994 when the AFL has had a top eight finals system. The 2017 Sydney Swans didn’t just lose their first four games – they dropped their first six. Given the historical record, the Swans should have no shot at the finals this year, but they’ve clawed their way back into contention.

Squiggle on Round 15

There was a Great Pancaking this round, with previously strong Attacks faltering and weaker Attacks standing up. On the chart, this looks like teams coming together on the vertical axis while moving in different directions horizontally:

That gives us a league where teams have very different Defences but on Attack can be roughly grouped as:

  1. Adelaide
  2. Everyone else
  3. Fremantle and Carlton

It was a super week for Richmond, who booked an interstate win over finals rival Port Adelaide while two other finals aspirants in Melbourne and Essendon faltered. As did the Bulldogs, although that result helped West Coast, so wasn’t as clearly positive for the Tigers. You can’t have everything. But it was a perfect storm of results for Richmond, making finals very likely and Top 4 a 50/50 proposition.

For many of the same reasons, Sydney also had a great week, recording a solid interstate win against Melbourne.

At the other end of the ladder, Hawthorn’s win over the Pies was significant, because when you’re competing against teams down there, you don’t need many wins to leapfrog them. Only two rounds ago, the Hawks looked reasonably likely to finish 17th, but after defeating Adelaide and Collingwood, that’s almost certainly not going to happen.

Now! Let’s take a moment to marvel at how bad the Giants-Cats draw was for Adelaide. You would think it was a good week for the Crows: They were the only one of the top 4 to win. But when you’re one of the three top teams, and the other two are playing each other, and you have a superior percentage to both, the one result you don’t want is for them to draw. In terms of deciding ladder positions relative to Adelaide, that’s just the same as if the Giants and Cats both won. (Assuming no more draws.) So that sucks, if you’re a Crow. Last year, Adelaide were screwed out of a Top 4 spot last year by Hawthorn’s freakish collection of close wins, so it would be really something if they get done again.

The Suns and Eagles did well, but it was a bad week for many teams: Melbourne imploded about two seconds after a successful season looked in sight, combining a loss with injury and likely suspension. Essendon did the same thing, at least the implosion part, only more spectacularly, going down to Brisbane at home. Brisbane! Just when you think you know a team.

Collingwood failed in that Collingwood way, where the result isn’t disastrous enough to prove they’re a terrible team, but screws up their season.

And Port Adelaide failed to beat another Top 8 team – which is a bad look, but the Flat Track Bully idea is still entirely mythical, as far as I can tell. You expect a team every now and again to string together close losses to good teams plus thrashings of bad teams just from random chance, without implying any kind of fundamental flaw in their game plan that prevents them from beating quality opposition. The Flat Track Bully idea also seems to contain a healthy dollop of confirmation bias, because everyone stops talking about it the second a result doesn’t fit the narrative, then resumes again a few weeks later as if nothing happened. (See: West Coast.)

So that’s probably Port Adelaide: an above-average team with a quirky results distribution.

Suddenly you need 13 wins for the Top 8 again. Really, though, there are seven teams who could finish 8th without surprising anyone: Port, Richmond, Sydney, Melbourne, West Coast, the Bulldogs, and St Kilda. Add some surprise and it could be Geelong or Hawthorn!

Port are still a good shot for Top 4, but you can see the true horror of their weekend here:

And look! 2017’s one constant, Brisbane, is no longer a dead cert for the wooden spoon. They’re still about 90% likely. But with home games against Carlton, the Bulldogs, the Suns, and North, it’s possible to imagine a future in which the Lions get up off the canvas.

To Flagpole! Sydney’s high position doesn’t look so silly now, does it? No. It does not.

Richmond remain concerning. I mean concerning if you support Richmond. Otherwise they promise a hilarious finals flame-out. The Tigers are coming in with one of the worst Attacks in modern history, and traditionally that hasn’t gone very well.

DID YOU KNOW??? Today’s fun fact! Only the Western Bulldogs have a non-ridiculous chance to finish either first or last. They have a 0.1% chance to finish in top spot and a 0.002% chance to finish last. (Next most likely are Essendon, who have a 0.0005% chance of finishing top, which is 1 in 200,000. For me, that crosses the line into ridiculousness. You may have different standards.)

Every Shot in the 2017 Coleman Medal Race

Figuring Footy compares the Coleman Medal contenders:

The injury to Josh Kennedy is dragging on. With Adam Simpson ruling out the two-time Coleman medalist from the Eagles’ elimination final rematch with the Dogs on Saturday, the calf injury that was originally expected to see Kennedy miss just the one game is now stretching into its sixth week. This is bad news for the Eagles, but it does have the positive side effect of throwing the race for the Coleman medal wide open.

Squiggle on Round 14

That’s a whole lot of teams nowhere near the premiership area!

It was an open field this time last year, too, but at least we had a few contenders. Most years, there’s usually at least one team snuggled in among a few premiership cups. But this year no-one’s been able to deliver sustained performance.

That makes for a volatile season, and the chance for someone to make a late run, or even do a Bulldogs 2016 and win it from way back. Something dramatic like that.

It’s not 1993-even. But it’s pretty even.

It was a great week for two teams, Port Adelaide and Melbourne, who put together impressive victories while their Top 4 competition in Adelaide and Geelong stumbled. Huh, it feels a little weird to be putting “Melbourne” and “Top 4” in the same sentence. What a world we live in. Anyway, the only thing that could have gone better for the Demons would have been if Fremantle slotted that last goal against the Cats, just to open that door a little further.

Squiggle is very disappointed in Geelong, because it doesn’t rate Fremantle much. So it was a dishonourable victory for the Cats, and they slide toward the middle of the pack.

Melbourne’s rise isn’t great news for Sydney, who play them this week. That one should be a great match.

Port get reward for a solid victory over Collingwood, again rolling out a very strong defensive effort in keeping the Pies to 9.8 62. Collingwood really have gone nowhere this year: they’re almost exactly where they started, and haven’t journeyed anywhere in the meantime. West Coast are similar.

Essendon, on the other hand, get better each week! Losing to the Swans in Sydney by a single point is good enough to send the Bombers flying up, up, again, like they have each week since Round 7 with the sole exception of their Round 10 loss to Richmond.

Things are very close in a few key areas there, and the Tower of Power (which is generated by a slower, more thorough series of simulations) disagrees, thinking GWS are more likely to snag an extra win and finish ahead of the Crows, Geelong will hold onto a Top 4 spot, and the Bulldogs will make the finals at West Coast’s expense:

Adelaide’s loss hurts their chances of finishing top quite a lot, partly because of missing the four points, and partly because what does it say when you lose at home to Hawthorn. It says you might not win enough games to finish top of the ladder, that’s what.

Meanwhile, no-one wants 17th! Every time Carlton or Hawthorn look like locking it down, they pull off an upset win.

Meanwhile on flagpole, it’s the same as always.
