As you probably know, I'm a big fan of communicating complex and statistical information
graphically. So you won't be surprised to hear that I'm also a big fan of
The Economist, the
masters of the interesting and thought-provoking chart. Here's a graph from the magazine showing a
ranking of "football wealth" based on the just released "Football Money League" report by
consultancy Deloitte.
Following up on my post about shot creation versus shot conversion as measures of offensive
production (see also the
On Football post), here's a quick and dirty analysis of Premier
League teams' ability to degrade opponents' shot
frequency (measured by shots allowed) and
shot
accuracy (the ratio of shots on target to shots allowed).
Ever since I started calculating shot to goal ratios as well as conversion and accuracy ratios of
teams' offensive (and defensive) production, I've been concerned that these ratios do not tell the
full story of what happens on the field.
Conversion, you may remember, is the ratio of goals
to shots on target - that is, how many of the high quality chances teams generated actually
resulted in goals: how good teams are at finishing.
