Idk I'm in a mood so I'm commenting the same thing again, but, I think the scaling is messing up your logic here.

So the pats looked pretty close to the top corner, but this chart doesn't actually say how much they were beating the chiefs in defensive EPA or how much they were losing in offensive EPA.

They could have been winning the defensive EPA by 3 points and losing the offensive one by 5, and the chart wouldn't be able to show it, so long as the spread on the defensive axis was much tighter than the spread on the offensive axis.it could go the other way too, I'm just saying this chart doesn't necessarily lead to your conclusion.

I think this is amusing, because basically, to draw the conclusion about who is better in overall EPA in any given week, the pats or the chiefs, you must also consider how bad the lions and bears played (or whoever is setting the 0 that week on each axis).
