So, we still have half of the teams in the Top 8 ranked in the bottom 6 for Own Scoring Shot Conversion, and five of them ranked in the bottom 9 for Opponent Scoring Shot Conversion. What a strange year …

Given all that, though, the 10-year-old MoS Win Prediction Function continues to do a good job of predicting team winning percentages as a function of scoring statistics. The rank correlation between its ordering of the teams and that based on the ladder ordering (adjusted for games played) is now at +0.92.

MatterOfStats 2020 : Team Dashboard for Round 10

You know that the season’s probably a weird one when

  • the team who’s 1st on Scoring Shot Conversion is 2nd on the competition ladder, and the team who’s 18th is immediately below them and 3rd on the ladder

  • the team who’s 4th on the ladder is 10th on Q1 performances, 11th on Q2 performances, and 15th on Q4 performances

  • the team who’s 2nd-last on the ladder is 3rd on Opponent Scoring Shot Conversion, 6th on Q2 performances, and 8th on Q3 performances

  • the correlation between competition ladder position and Q4 performances is only +0.26, and that between competition ladder position and Q1 performances is only +0.82

The latest Rankings on Dashboard Metrics table appears below.

No in-depth commentary this week other than to note that there are some teams in lofty ladder positions that are performing relatively poorly on some of the metrics (eg the Lions are last on Own Scoring Shot Conversion), and teams towards the cellar that are relatively high-performing on some metrics (eg the Roos are 1st on Opponent Scoring Shot Conversion).

MatterOfStats 2020 : Team Dashboard for Round 7

The latest Rankings on Dashboard Metrics table appears below.

Of all the metrics, the MoS Win Production Function continues to show the highest rank correlation with teams’ ladder positions.

It suggests that:

  • Adelaide has won 1.2 games fewer than might be expected given its scoring statistics

  • Fremantle has won 1.0 games fewer

  • Essendon has won 0.9 games more

  • Brisbane Lions and Hawthorn have won 0.8 games more each

Every other team is within 0.6 wins of what would be expected.

MatterOfStats 2020 : Team Dashboard for Round 4

Here’s the latest Rankings on Dashboard Metrics table, which reveals the following interesting facts:

  • Port Adelaide, though Top 2 on every other metric, is 11th on Own Scoring Shot Conversion

  • Gold Coast is 12th on Scoring Shot generation

  • Brisbane Lions are 18th on Own Scoring Shot Conversion, and 15th on Opponent Scoring Shot Conversion

  • Hawthorn are 14th on Opponent Scoring Shot Conversion, and 16th on Q4 performances

  • North Melbourne’s statistics are all over the place: bottom half on Opponent Scoring Shot generation, Own Scoring Shot Conversion, Own Goals and Points per Game, and Q1, Q2 and Q3 performances, but top half for all the other metrics including 1st on Opponent Scoring Shot Conversion and Q4 Performances

  • Adelaide are 6th on Own Scoring Shot Conversion, and 4th on Opponent Scoring Shot Conversion, but 18th on both Own and Opponent Scoring Shot generation

MatterOfStats 2019 : Team Dashboard for Round 23

The final table of Rankings on Dashboard Metrics appears below.

There are a number of metrics on which some teams higher on the ladder do surprisingly poorly, and others on which some teams lower on the ladder do surprisingly well, but we’ve covered a number of examples of these in recent weeks, so I’ll leave it to the reader to undertake a final review of these for themselves.

This week, we’ll have one final look at the MoS Win Production Function and what it suggests about how many more or fewer wins teams have recorded relative to what their scoring metrics would suggest they might reasonably have been expected to.

MatterOfStats 2019 : Team Dashboard for Round 22

The latest table of Rankings on Dashboard Metrics appears below, one striking feature of which is the contrast between the rankings on metrics for the teams from 1st to 6th on the ladder with those for the teams from 7th and 8th - Essendon and the Western Bulldogs.

  • Essendon is no higher than 4th on any metric, and is 10th or worse on 10 of the 14 metrics.

  • The Western Bulldogs are 4th or better on only two metrics, and 10th or worse on eight metrics.

  • Hawthorn, in contrast, who currently sit 9th on the ladder, are ranked 5th or higher on six metrics, and 10th or worse on only six metrics. They are also 7th on Expected Wins, while the Western Bulldogs are 8th, and Essendon 12th.

  • Geelong are ranked no lower than 4th on any Dashboard metric

  • Brisbane Lions are only 7th on Opponent Scoring Shots, 11th on Own Conversion, 8th on Opponent Conversion, 9th on Goals Conceded, and 10th on Points Conceded

  • West Coast are only 9th on Scoring Shot Production, 11th on Opponent Scoring Shot Production, and 13th on Q2 performances

  • Richmond are 15th on Opponent Conversion, 10th on Goals Conceded, 9th on Points Conceded, and 12th on Q4 performances

  • Collingwood are 9th on Opponent Conversion, 14th on Q2 performances, and 11th on Q3 performances

The latest table of Rankings on Dashboard Metrics appears below.

While there’s still a very high correlation between the teams’ ladder positions and their ordering based on Expected Wins according to the MoS Win Production Function half of the teams find themselves with at least one or more wins or losses greater than their scoring statistics would suggest, namely:

  • Sydney (2.6 fewer wins)

  • Port Adelaide (1.3 fewer wins)

  • Carlton and Hawthorn (1.2 fewer wins)

  • Adelaide (1.1 fewer wins)

  • North Melbourne (1.0 fewer wins)

  • St Kilda (1.9 fewer losses)

  • Richmond (1.8 fewer losses)

  • Brisbane Lions (1.7 fewer losses)

  • Essendon and West Coast (1.3 fewer losses)

In terms of ladder positions, however, it’s the Western Bulldogs who find themselves highest on the ladder relative to their Expected Win count. They’re in 10th on the ladder but are ranked only 14th on Expected Wins.

MatterOfStats 2019 : Team Dashboard for Round 19

The latest table of Rankings on Dashboard Metrics appears below.

It shows that, as interesting as the 2019 season might be, we have to be honest and recognise that most of the teams currently in the Top 8 have flaws, some of which can be summarised by:

  • West Coast’s 10th on Scoring Shot creation, 12th on Scoring Shot concession, 13th on Q2 performances, and 8th on Q3 performances

  • Brisbane Lions’ 11th on Own Scoring Shot Conversion, 8th on Opponent Scoring Shot Conversion, 10th on Goals and Points Conceded per Game, and 9th on Q1 performances

  • Richmond’s 15th on Opponent Scoring Shot Conversion, 12th on Goals and 11th on Points Conceded per Game, and 14th on Q4 performances

  • GWS’ 11th on Opponent Scoring Shot Conversion, 8th on Q1, and 9th on Q2 performances

  • Collingwood’s 9th on Opponent Scoring Shot Conversion, and 14th on Q2 and Q3 performances

  • Essendon’s 13th on Scoring Shot creation and on Scoring Shot concession, 10th on Points Scored per Game, 9th on Points Conceded per Game, 14th on Q1 performances, and 12th on Q2 performances

  • Adelaide’s 10th on Own Scoring Shot Conversion, 10th on Q1 and Q3 performances, and 12th on Q4 performances

It’s also true that many of the teams outside the Top 8 have performed extraordinarily well on some metrics, including, for example, Sydney’s 4th on Opponent Scoring Shot Conversion, 6th on Q3 performances, and equal 6th on Quarters won.

The latest table of Rankings on Dashboard Metrics appears below.

Based on the MoS Win Production Function, the current Top 8 on the ladder are those with the highest Expected Wins, albeit in a different order. The largest differences between Actual and Expected Wins now belong to:

  • St Kilda (+1.8 wins, Actual less Expected)

  • Richmond (+1.5 wins)

  • Brisbane Lions (+1.3 wins)

  • West Coast (+1.1 wins)

  • Sydney (-1.9 wins)

  • GWS (-1.7 wins)

  • North Melbourne (-1.3 wins)

  • Adelaide and Carlton (-1.1 wins)

MatterOfStats 2019 : Team Dashboard for Round 17

The latest table of Rankings on Dashboard Metrics appears below.

Based on rank correlation the metrics most highly correlated with the current competition ladder ordering are the orderings based on:

Those metrics least correlated are:

  • Q2 performances (+0.34)

  • Opponents’ Scoring Shot Conversion (+0.43)

  • Q3 performances (+0.57)

  • Q4 performances (+0.61)

  • Q1 performances (+0.65)

The relatively low correlations between ladder positions and performances in individual quarters I think reflects the fact that no team - Geelong aside - has been able to dominate in every quarter. All of the teams in positions 2 through 8 on the competition ladder are ranked 9th or lower for at least one quarter, most of them for two quarters.

The latest table of Rankings on Dashboard Metrics appears below.

Currently, the rank correlation between the teams’ ordering based on the MoS Win Production Function and that based on the competition ladder stands at a remarkable +0.96, suggesting that teams are (almost) ordered the same way based on both metrics.

That said, according to the MoS Win Production Function:

  • St Kilda have won 1.7 games more than their scoring metrics would imply

  • West Coast have won 1.3 games more than their scoring metrics would imply

  • Richmond have won 1.2 games more than their scoring metrics would imply

  • Brisbane Lions have won 1.0 games more than their scoring metrics would imply

  • Melbourne have won 0.8 games more than their scoring metrics would imply

  • Carlton have won 1.8 games fewer than their scoring metrics would imply

  • GWS have won 1.4 games fewer than their scoring metrics would imply

  • Hawthorn have won 1.2 games fewer than their scoring metrics would imply

  • Sydney have won 1.0 games fewer than their scoring metrics would imply
