The trouble is Robbie this is still unconvincing. When our xGa is close to 50% higher than actually conceded, it suggests maybe the xGa stat is not quite working. Swansea and Watford are also miles off their xGa.
And you have told us before that you do not believe this is poor finishing - right? Because otherwise you would not argue when we point to our xG being six goals higher than our actual goals scored that it is nothing to do with poor finishing...
It’s all a bit inconsistent. Which really just highlights why xG and xGa are massively flawed and, while interesting, don’t really tell us something concrete.
Especially as they’re also vulnerable to manipulation - for example, recently you have often changed how you use the xGa stat by arguing that one big chance xG is worth more than lots of little xG chances (even though that would defeat the object of having xG percentages as if they are correct than 75% made up of multiple small chances should have exactly the same odds of a goal as one shot with a 75% chance...)
But I can also manipulate the xGa stats for Norwich across matches even if we swallow the idea of xGa being accurate - for example, over the last six matches our average xGa per match is 0.867. That would put us top of your table by a massive margin on a seasonal basis.
But that’s only recent form you say? Well Ok, let’s take our last 15 matches. Well our xGa for that period 0.872 - so only a fraction higher. So our excellent defensive form has actually been for an extended period of time!
But that’s less than half the season I hear you say - Rob you’re picking the best periods to show us in a better light. Well ok, let’s go back 20 matches then. Ah! Well now we are talking - our xGa has shot up to 0.97 per match! But hang on a second... That would still see us second in the defensive table... So still pretty good.
Even if you back 25 matches we are still almost exactly 1 goal xGa a game. If you want to get clever and look at only our possible opponents next year, in that same period of xGa is 1.06 against top six teams.
The point being we all knew our form at the start of this season was shaky and our defence wasn’t great, but since January in particular it has really clicked. Stats shouldn’t be looked at in a vacuum, they should always be contextualised, their flaws acknowledged. Lies, damn lies and football stats.
