E Ratings update: League 1, 10 Feb 2019
Here is the latest update of the E Ratings and how they predict the rest of the season will pan out. The rating system is explained here, but in a nutshell it’s based on the combined quality of chances that clubs create and allow, rather than their results.
The attack rating broadly equates to how many goals’ worth of chances a team would create against an average opponent (so higher is better), with the defence rating equivalent to the chances they’d be expected to allow (so lower is better). The overall rating is the difference between the two – effectively the average expected goal difference per match – so a positive number is good and a negative one is bad.
The graphic below lists each club in descending order of their overall E Rating and shows how this – along with their individual attack and defence ratings – has changed over the past 30 league matches. The red and green arrows indicate how the overall rankings have moved in the past month and the numbers in brackets show the ranks for each team’s attack and defence ratings.
Barnsley and Luton are vying for the status as the best-rated team in the division, with a somewhat stalling Portsmouth their only serious challenger. Doncaster‘s big win over Peterborough continued their respective trajectories, with Donny looking like serious promotion contenders now. There’s no sign of a recovery in Gillingham‘s performances yet, while Scunthorpe continue to defy gravity with their strong form not being reflected in the underlying data.
Predicting the rest of the season
Below I’ve used each club’s current ratings and those of their remaining opponents to predict how the rest of the season could play out. Each of the remaining fixtures has been simulated thousands of times, using the current E Ratings to generate probabilities for where each club will finish.
This graphic shows the cumulative probability of where each club could end up, in descending order of average points won. You can think of the ordering of the teams down the left hand side as a “best guess” of the final league table, with the coloured bars showing the relative likelihood of each club ending up in a certain section of the table:
It’s a three-horse race for the two automatic promotion slots at the moment, with Luton still looking pretty comfortable and Barnsley increasingly so after both recorded wins by a three-goal margin. The top six is looking increasingly like a closed shop, with Peterborough and Blackpool running out of time to assert themselves. I have no idea what’s going on at the bottom of the table: barring Wimbledon and their ongoing misery it’s incredibly tricky to predict who will be dropping into League 2.
