League 1 timelines, 22-23 Sep 2017

A quick explanation

You can skip this if you’ve seen these before.

As usual, here are timeline graphics for the latest round of matches. There’s a full explanation of these here, but in a nutshell they track how each club’s expected goals tally (the number of goals that the average team would have scored from the chances that they created) increased over the course of the match.

This allows us to get a better sense of how each game played out than from just watching the highlights. Every jump in a line is a shot, with bigger jumps corresponding to more promising chances (at least as far as I can tell from the limited data available at this level).

There are two numbers next to each club’s name: the first is how many goals they scored and the second (in brackets) is how many goals the average club would have scored from their shots. The latter number is what the lines track, with dots on the lines denoting the goals they actually scored.

Individual matches

Fleetwood and Southend each scored almost immediately, with the hosts’ equaliser coming from the kick-off after the opener went in, but thereafter the visitors dominated and ran out convincing winners. There were even more dominant wins for Doncaster and Rochdale, while Rotherham left it late to inflict their damage on Oldham and Wigan look to have been hard done by in their narrow defeat at Peterborough.

Midweek games

For some time there’s been the problem of what to do when there’s a handful of midweek games. It doesn’t seem proportionate to run an entire blog post to contain just one match, and sticking them on Twitter is neither consistent nor makes them easy to find. Therefore I’ve decided to append them to the next full batch of timelines, starting here with Tuesday’s match between Wigan and Northampton:
