E Ratings update: League 1, 18 Feb 2017
Here is the latest update of the season to 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.
You can see how the model assessed the latest round of matches here. The changes are over the last seven days so will factor in the midweek matches too.
Sheffield United may not have gotten the win their performance seemed to deserve but it did their ratings no harm to out-create Scunthorpe so convincingly. I’m getting increasingly worried about the Iron’s promotion challenge as they continue to slip down the ratings.
While Southend were held to a draw and Walsall left it late to beat Peterborough, both extended their encouraging sequence of performances that have seen their ratings consistently rise.
While Shrewsbury have made real improvements under Paul Hurst they looked fortunate to win at home to Wimbledon, which on top of their flat performance at Peterborough in midweek has dented their rating. However it’s too soon to determine if their bubble is bursting.
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:
At the top it remains the case that Sheffield United are the runaway title favourites while Bolton and Scunthorpe are locked in a close tussle for second place. However draws for those three allowed Fleetwood to establish themselves as dark horses with a narrow win this weekend.
Bradford and Millwall look likely to complete the final top six, with three other clubs looking potentially capable of dislodging them if they can get their act together.
At the bottom Coventry‘s narrow victory over Gillingham saw Chesterfield replace them as relegation favourites after the Spireites’ late collapse at home to Bury. However both are still incredibly likely to go down, with Swindon‘s potentially costly failure to beat Oldham keeping them in similar danger.
