2021 - Team Ratings After Round 4
/MoSSBODS, despite re-ranking 14 teams this week, left the Top 3 unchanged as Western Bulldogs, Melbourne, and then Richmond, and left North Melbourne in bottom spot. MoSHBODS re-ranked 13 teams, but left Western Bulldogs in first, Melbourne in second, and North Melbourne in last place.
The big movers on MoSSBODS were St Kilda and Fremantle, who both climbed three places, and Gold Coast, who fell four. On MoSHBODS, the only teams to move more than two places were GWS, up three spots, and Gold Coast and Hawthorn, both down four.
The correlation between MoSSBODS and MoSHBODS Combined Ratings now stands at +0.996.
On the Component Ratings MoSSBODS and MoSHBODS now have Top 3s of Dogs, Swans, and Dees, while on Defence, MoSSBODS has it as Dees, Pies, and Dogs, and MoSHBODS as Dees, Dogs, and Pies.
On MoSSBODS, 7 teams are now rated positively on offence and defence (up 1), 5 are rated negatively on both (up 1), 3 are rated positively on offence but negatively on defence (down 1), and 3 are rated negatively on offence but positively on defence (down 1). The correlation between the teams’ MoSSBODS offensive and defensive Ratings now stands at +0.557, which is up a little on last week’s number.
And, finally, to MARS, which re-ranked only eight teams this week, but left Port Adelaide and Richmond as the Top 2.
Only three teams moved by more than a single spot: GWS (up 3). Western Bulldogs (up 2), and Essendon (down 2).
With Collingwood now Rated at 999.3, MARS has only eight teams rated as better-than-average, with nine more Rated 988 or above.
The Rating gap between first and last now stands at just over 47 Rating Points (up about 3 Points). By comparison, at the same point last year the range was just 40.5 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 Fremantle where Rating System rankings are relatively lower than Ladder position, and for Richmond, Collingwood, and Brisbane Lions where Rating System rankings are relatively higher than Ladder position.
MARS continues to provide the most outlying rankings of the three Systems, it having the outright most-extreme ranking for 14 of the teams, with Melbourne and West Coast the most notable examples.
By comparison, MoSSBODS has the outright most-extreme ranking for five teams, and MoSHBODS for just four.
MoSSBODS and MoSHBODS now agree about the ranking of nine teams, MoSSBODS and MARS about the ranking of four teams, and MoSHBODS and MARS about the ranking of only two teams, Fremantle and North Melbourne.
Lastly, if we consider the range of rankings that the three Systems have attached to each team, we find that West Coast (5 spots) still has the widest range of rankings, while nine teams have rankings that differ by no more than 2 spots, including Fremantle and North Melbourne for which all three Systems have the same ranking.
