League 1 timelines, 7-8 Oct 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

First of all: Bristol Rovers getting an expected goals value of 5.7 is incredible, even accounting for it being against 10 men. That’s the biggest total I’ve seen since I started recording these regularly in 2014/15, and they’ve already got form in this area:

Elsewhere it looked like the scoreline in Oxford’s win over Wimbledon flattered them somewhat, but the only match not to see the team with the largest expected goals total win was a scrappy encounter between Walsall and Shrewsbury.
