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

Bristol Rovers were the only team not to score last night – I’ll have to remember to look up how long it’s been since that happened (and when every team in the division last scored on the same day) – with Shrewsbury continuing their incredible start to the season. Blackburn actually look to have created slightly better chances than the Shrews overall, but were held to a frustrating draw by Plymouth. There was a precious win for Wimbledon at home to travel-sick Rotherham, although the data suggests that the performance was less encouraging than the result: secured via a late surge rather than a dominant shooting display.
