Great piece, John. Could you elaborate on the process you used to determine PPDA for each team, especially regarding the scaling of values from comparable competitions you mentioned in the footnotes, and how you went about that?
Definitely. American Soccer Analysis has location-based passing data for each third of the pitch, so used that for the “passes allowed” segment. The “defensive actions” portion was a bit more naive; I used tackles and interceptions by non-defenders to derive that.
The team-by-team numbers from there weren’t bad, but I decided to normalize them against standard PPDA numbers from MLS and NWSL just to make the scale a little bit more legible to anyone who’s familiar with those leagues.

Lovely piece John, by last time I check the Velocity play in USL1 😂
I was SO sure I caught all of those, ughhhh
(thank you!)
