Round 5 - AFL Men’s ratings updates and preview

After a pretty brutal Round 4, we saw some big movements in our ratings. That leads to some interesting matchups this week. Read on to see who our model is tipping!

Also a quick reminder that you always find full ratings and current tips updated each Monday.

Ratings and Simulations

The big loser here was clearly Adelaide, after a shock, heavy loss to Collingwood. They dropped from pretty clear top rated team down to 4th. Their Finals chances took a big hit, dropping down to 8th on our average simulated season ladder with a finals chance now below 70%.

Richmond’s big win vaulted them up to top spot on our ratings and also our simulated season! They finish top spot in nearly 30% of all (albeit very early) simulations.

Ratings wise, there is now a pretty linear progression from 1st down to 9th, with maybe two groupings of top 4 (Richmond, Sydney, GWS, Adelaide) and 5th-9th (Geelong, West Coast, Port Adelaide, Hawthorn, Collingwood). These top 9 are, as expected, also finishing making finals in most simulations. All have >60% chance of reaching September.

There is a pretty big drop off after that to three even teams in North Melbourne, Melbourne and Essendon, all sitting just below the average rated team. They aren’t out of finals by a long shot but only make it that far in about 30% of simulations.

There is another drop to the Dogs, Saints and Dockers group before we have a decent step back to our cellar dwellers in Brisbane, Gold Coast and Carlton. All of those teams would have to launch a pretty epic turnaround to make it even from this early stage you’d think.
