Predictably post game conversations have focussed on inaccuracy as a systemic problem in the competition. Some argue that not enough is done to develop the goal kicking skills, particularly encouraging players to have a set routine for their shot at goal.

Before we leap to conclusions let’s see the facts. The chart below shows the average ratio of goals to points since the start of the (VFL) competition. There is a surprising amount of variation in accuracy from year to year but quite clearly, there is an upward trend since the 1950s. In 1956 the average team scored 10 goals 12 behinds. In 2008 it was 14 goals 12.

So there it is. Perhaps all players don’t need a ritual like Matthew Lloyd’s and Fev’s miss was “just footy”!

When it comes to Carlton and West Coast more analysis might be needed. Carlton’s trend is upwards, although not as strong as the competition average. For West Coast there is much less data and possibly reflects the performance over than time. I’ll look at that in another post.

Finally, if you would like to see what the accuracy looks like for each team, here it is.

Data is for the Home and Away Competition to the end of 2008.

This is the basic dashboard I am using to explain some simple statistics to my 9yo. It kept his attention for more than 2 minutes which is a good outcome around here!

Carlton Dashboard

As we are Carlton fans we started with some Carlton match statistics over the last three years. You can download the dashboard as a PDF or as a packaged workbook. If you don’t have the Tableau Software you can download a trial here or a free viewer here.

The interactive version allows you to select teams to compare. In this static image I show Carlton’s performance against non-Victorian teams.

I am playing with other AFL statistics, especially recent wins and attendance stats. If you have any ideas for analysis or would like to see something similar for another team please let me know in the comments. Of course there are a few teams I won’t enjoy too much.
