2018 Rd 4: Carlton vs North Melbourne in Hobart

[LP]

To not overcomplicate issues, my reference to speed included acceleration ie speed off the mark...players on the lead falling under that umbrella.

Joe the goose is probably an inability (or want) to get back on the fast break, so speed could be a factor...or at worse, good damage limitation.
Pack marks probably comes down to height.

So 3 out of the 4 comes down to the 2 key factors i mentioned, height and speed.

Joe the Goose is always 100% caused by extra numbers around the ball carrier, speed is never the issue. No extra numbers, no Joe the Goose, and it is rarely if ever caused by the defence, it's nearly always caused by players allowing overlap further up the field.
