Squiggle on Finals Week 1

a.k.a. “Richmond goes wheeee!”

Throughout the season, the squiggle refused to rate Richmond any higher than a somewhat-above-average team. Now there are only six teams left, the Tigers are rated 3rd, i.e. still just on the better side of average. But they made a big move after holding Geelong to only 40 points, essentially pulling level with Adelaide in terms of raw form.

That’s still not enough for a flag, because squiggle respects the historical fact that attacking teams have outperformed defensive teams when it counts over the last two decades. So while the Tigers have a dream run to the Grand Final, avoiding both top teams and hosting an interstate opponent for a prelim, squiggle doubts they can contain the scoring power of Adelaide or Sydney if they get there.

Nevertheless, the Tigers are certainly close enough to give it a shake, which is just about the most exciting thing I’ve experienced in my entire football-following life. So that’s something.

There’s not a whole lot to say about Adelaide v GWS or Sydney v Essendon, both of which played out to expectation.

But Port v West Coast! Once again, the Power failed to knock off a well-rated opponent, although only just, in the cruelest possible way. Taking an 8 scoring shot advantage and turning it into 2 fewer goals and 10 more behinds is going to sink any team.

Despite all the evidence Port has offered to the contrary, there’s still reason to believe they’re a very good team, and if they can avoid self-immolating over the off-season, they could follow in the footsteps of Sydney 2015, who kicked themselves out of their first final against Fremantle (7.18 to 10.9), then rebounded the next year to win the minor premiership and contest the Grand Final. Port’s stumbles in 2017 have been absurd, dramatic and memorable, so it’s easy to forget they annihilated the bottom tier of the competition, beat most of the middle tier, and weren’t too far off the rest, while recording wins over Sydney and West Coast.

Meanwhile, the Eagles are lurking just close enough to be dangerous. All year, they’ve been thereabouts, competitive in practically every game, including those against everyone they have to beat for the flag. They are rightly underdogs, but having landed on the soft side of the draw, it’s not beyond the realm of possibility that the Eagles could defeat the Giants, who they only lost to by 8 points earlier this year, then Richmond, who they lost to by 11, and then take on Sydney or Adelaide, both of whom they’ve beaten.

An Eagles flag would be mind-boggling, given they were unlikely even to make finals a few rounds ago. In another year, I’d say it was fanciful, because normally we have at least one truly dominant team plus a tradition of rested Qualifying Final winners beating up Semi-Finalists. But this year, our top two in Adelaide and Sydney haven’t created as much separation from the field, you only have to beat one of them (unless you’re Geelong), and there’s the unknown quantity of the pre-finals bye in play. So almost anything is within the realms of possibility.

On flagpole, it’s bombs away and lights out!

Richmond squeak into 3rd even with the heavily defensive game plan that Flagpole abhors. And Geelong are still rated pretty well, even though in the real world everyone has concluded that they are the worst football team to ever play the game and who will win that Adelaide v Sydney prelim.

Geelong Cats v Sydney Swans

There’s a long history, of course, of people overrating Elimination Final winners and underrating Qualifying Final losers. But it’s still hard to see Sydney dropping this one: They’re a premiership favourite who finished much lower on the ladder than their form suggested, while the Cats made top 4 on the back of a few close wins and didn’t fire a shot against the Tigers.

GWS Giants vs West Coast Eagles

This one is harder to pick, with neither team having stood out over the season, but both also refusing to go away. In a neutral venue, squiggle would pick the Eagles, but only just; in NSW, it gives it to the Giants.

I’m just going to stare at that for a while now. I basically made that Squiggle Doors function just so I would have an excuse to imagine Richmond Grand Finals in alternate universes. Now there might be one in this one! That’s even better.

By the way, I would also like to take this moment to enjoy when hardly anybody has started hating Richmond crowds yet. I know that’s coming, because Richmond crowds when the Tigers are on the verge of success are the fucking worst. Not for me. They’re fine for me, because I’m wearing yellow and black. But for other teams’ supporters. I didn’t see anything bad at the Geelong game, but I’ve been to every final of the last five years, and they bring out plenty of mentally damaged individuals who have been psychologically broken by the last 35 years of heartache and now clearly believe they are the plaything of a malevolent deity who can only be banished by a spray of alcohol-fueled insults. If we make a Grand Final, it’s going to be so ugly. I mean win or lose, either way, there is going to be some shit on display. So it’s nice to get in before that.

Models Leaderboard After Home & Away

2017 has been a rough year for tipping, even tougher than 2016, which itself was a wake-up call after the lovely, predictable Hawthorn dynasty.

Sadly, none of the models managed to outperform the bookies in tipping winners head-to-head during the Home & Away season, nor in terms of probabilistic Bits.

A particularly rough year for Squiggle’s in-house tipping algorithm, which came in dead last and didn’t deserve to be any higher. But very credible performances elsewhere, especially from Plus Six One (for the second year in a row), and it’s worth noting The Arc‘s chart-topping Mean Average Error in a year when the line-ball games didn’t fall their way.

I was curious this year to see what kind of performance the Aggregate would have, where it represents a simple average of everyone else’s tips. Would there be some kind of wisdom of the crowds effect, where it could outperform most of the individual models that provided its inputs? Well, kind of: It landed mid-table in terms of tips and MAE, but with more Bits than all models. So there could be something there.

Apologies for finals tipping being a little shaky at the moment: Apparently everyone (including Squiggle) uses different formatting for posting their finals tips, and squiggle-bot needs to learn how to parse it.
