2021 - Team Ratings After Round 13

Only four teams changed order on MoSSBODS and MoSHBODS this week, and none of them in the Top 8 for either System.

The big movers were Collingwood, up 5 spots to 10th on MoSSBODS, and up 4 spots to 9th on MoSHBODS, and Sydney, down 3 spots to 14th on MoSSBODS, and down 3 spots to 13th on MoSHBODS. GWS also fell 2 spots on MoSHBODS and into 11th.

The correlation between MoSSBODS and MoSHBODS Combined Ratings now stands at +0.9980, and the Rating gap between 1st and 8th remains at 8.2 Scoring Shots on MoSSBODS and 28.8 Points on MoSHBODS, with the Dogs and Blues both having byes. Only seven teams are rated as above average.

On the Component Ratings, on Offence MoSSBODS now has a Top 3 of Dogs, Lions, and Cats, while MoSHBODS has Dogs, Lions, and Dons. On Defence MoSSBODS’ and MoSHBODS’ Top 3s are still Dees, Dogs, and Cats.

On MoSSBODS, 5 teams are now rated positively on offence and defence (no change), 7 are rated negatively on both (no change), 2 are rated positively on offence but negatively on defence (no change), and 4 are rated negatively on offence but positively on defence (no change). The correlation between the teams’ MoSSBODS offensive and defensive Ratings now stands at +0.700, which is up a fraction on last week’s number.

In the animation below, we can see the path that each team has taken to arrive at its current Rating.

And, finally, as always, to MARS, which re-ranked only two teams this week, swapping Fremantle and St Kilda.

No teams moved by more than a single spot.

MARS now has only seven teams rated as better-than-average, but now has six more Rated 990 or above.

The Rating gap between first and last now stands at almost 68 Rating Points and that between 1st and 8th at just over 30 Rating Points. 1st and 6th, however, are separated by just under 12 Rating Points, and 8th and 15th by just under 14 Rating Points.

The biggest gaps in the Ratings are between 7th and 8th (14.2 Rating Points), and between 17th and 18th (18.2 Rating Points)

Looking across the rankings of all three Systems and ordering the teams based on the current competition ladder, we find the highest differences for Collingwood, Carlton, and Essendon where Rating System rankings are relatively higher than Ladder position, and for Sydney, West Coast, and Adelaide, where Rating System rankings are relatively lower than Ladder position.

MARS continues to provide the most outlying rankings of the three Systems, it having the outright most-extreme ranking now for all but three of the teams - the three lowest-ranked.

By comparison, MoSSBODS has the outright most-extreme ranking for three teams, and MoSHBODS has it for only one.

MoSSBODS and MoSHBODS still agree about the ranking of 14 teams, MoSSBODS and MARS about the ranking of three teams, and MoSHBODS and MARS about the ranking of the same three teams.

Lastly, if we consider the range of rankings that the three Systems have attached to each team, we find that Sydney has the widest range of rankings (six spots), while 12 teams have rankings that differ by no more than two spots, including Adelaide, Hawthorn, and North Melbourne, for which all three Systems have the same ranking.
