Opponent Displacement Indicator (OD-Indicator)
Level: Team Report
What: Average movement (in meters) of all defending outfield players (OD-I) provoked by all successful passes over the whole match.
Why: Indication for the displacement of the opposing team’s defensive organization. The feature Opponent Displacement Indicator is based on passing disruptiveness.
Interpretation: The higher this value the more displacement of the opposing team which often leads to creating space and disturbs the defensive organization.
The basic idea behind this model by Goes and colleagues (2018) is that a good pass will lead to more individual movement (“I-Mov”) and disruption of the defence (“D-Def”). These measures focus on the interaction process of both teams and not (like most models) solely on the scoring opportunity. In addition, this model does not overvalue forward passing.
Individual movement ('I-Mov')
Sum of the movement of each player of the opposing team.
Absolute displacement in de longitudinal (X) and lateral (Y) direction.
Sum of absolute displacement between pass (t0) and 3 seconds later (t0+3).
* 3 seconds is an arbitrary window
Opponent Displacement Indicator
We use de euclidean distance of all the opposing players in meters.
To allow comparing passes, the outcome is standardized to a displacement per second.
The "ODI" compass provides a quick indication of the movement of all players of the opposing team caused by a single pass.
The ODI can be seen as the displacement of the centroid of the team. For example the "Cteam" in figure 2, this is the total movement of the team.
Team centroid and tactical lines
Movement of a team can also be split up in movement per tactical line. For example the displacement of the centroid of the defensive line. Here you can find more info about team centroid, tactical lines, and positional structure.
