This is interesting and I would agree does have some validity, and the last month we have been appalling in front of the sticks.Sure, here you go.
WHAT IS EXPECTED SCORE?
Every shot on goal is analysed, based on where on the ground it was taken and how much pressure the player was under.
The expected accuracy of the shot is determined based on the results from that location and pressure level over the last decade of AFL matches.
What is expected score?
But according to the article this stat doesn't take into account the individual skill level of the player taking the shot under x amount of pressure from whatever part of the ground. (assuming because that's not possible to represent statistically due to limited sample size of individual players). So a team who has more players who convert set shots and shots under pressure better than average would often do better than the expected score?
Perhaps we are just a team who has poor overall skills at converting set shots or shots under pressure. We certainly have had this issue at various times for a few years now. So maybe this stat is actually hiding some of our players poor skills around goals because it only assumes we should be doing better over the last few rounds.
To be really simple, if van Rooyen has a shot I'm expecting a goal, if Petracca has a shot I'm expecting a point. Maybe the ball is ending up in the wrong hands too often, which could be a structural issue.
