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

It was a great day for Blackburn, who romped to victory on a day when Wigan were held and Rotherham crashed at home to much-better-than-the-league-table-suggests Rochdale. Dale’s fellow relegation battlers Bury had a rare productive day in front of goal but saw their precious two-goal lead cancelled out by an opportunistic Oldham, despite the Latics being comfortably out-created. Even more surprising was Portsmouth‘s defeat by Gillingham, who failed to trouble the home defence at all in the first half but somehow struck three times after the break.
