This is a criticism of the content, from the fantasy* PL and opta, not the post.
Not sure why opta analyst would generate this for any reason other than maybe promoting discussion on its own validity, as it's almost meaningless.
Barely 18% of the season has been completed so far.
This analysis runs a very funny line between statistical insignificance, and meaninglessness.
The vertical axis is a joke in that it's a contrived measurement with no explanation as to how it has been derived or what the scale represents, and despite the appearance of a wide range, the variance has all teams within a tiny range between the so called toughest and weakest average opponent.
The horizontal axis being simply an alternate representation of the league table, just horizontally.
A masterclass in 'How to crunch numbers yet provide nothing of value'.
