American Soccer Analysis does a lot of great things around the “stats” of soccer. There aren’t a lot of stats, but they are finding new ways to quantify what happens on the soccer field.
One of my favorite finds of 2020 is their beautiful graphical looks at expected goals (xG) over the ebbs and flows of a soccer match. Something they call gameflow (g+). I won’t pretend I can explain it, but they have a lovely explainer here.
You are probably familiar with the expected goal (xG) stat. It’s roughly based on where the shot was taken from and some other factors, they (and others) determine how likely the ball is to go into the net.
