2021 - Team Ratings After Round 2
/At the end of Round 2, the MoS twins now agree about the Top 4 and the Bottom 3 teams (and five other of the teams in-between).
They reached that conclusion by, in MoSSBODS’ case, reranking nine teams, including four by multiple places and, in MoSHBODS’ case, reranking 12 teams, including eight by multiple places.
The correlation between MoSSBODS and MoSHBODS Combined Ratings now stands at +0.9936.
On the Component Ratings there is more disagreement about who’s best on Offence, with MoSSBODS having a Top 3 of Lions, Tigers, and Cats, and MoSHBODS having a Top 3 Power, Lions and Tigers. On Defence, both agree that the Top 3 is Tigers, Pies, and Power.
On MoSSBODS, 6 teams are now rated positively on offence and defence (no change), 6 are rated negatively on both (no change), 2 are rated positively on offence but negatively on defence (up 2), and 4 are rated negatively on offence but positively on defence (down 2). The correlation between the teams’ MoSSBODS offensive and defensive Ratings now stands at +0.537.
And, finally, to MARS, which re-ranked 10 teams this week, but left the Top 6 unchanged, including the Tigers, Power, and Cats in the podium positions.
Just four teams moved by more than a single spot, and none by more than two spots.
With Sydney now Rated at 1,000.02, MARS has 10 teams rated as better-than-average, with five more Rated 990 or above.
The Rating gap between first and last now stands at just over 43 Rating Points (up 6). By comparison, at the same point last year the range was just over 46 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 Sydney, Gold Coast, and Hawthorn where Rating System rankings are relatively lower than Ladder position, and for Geelong 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 nine of the teams, with West Coast and Hawthorn the most notable examples.
By comparison, MoSSBODS has the outright most-extreme ranking for just three teams, and MoSHBODS also for just three.
Lastly, if we consider the range of rankings that the three Systems have attached to each team, we find that West Coast (5 spots) has the widest range of rankings, while 14 teams have rankings that differ by no more than 2 spots, including Essendon, Fremantle, Geelong, North Melbourne, Port Adelaide, Richmond, and Sydney, for which all three Systems have the same ranking.
