From: Measuring skill via player dynamics in football dribbling

Normalized histograms of empirical distributions for selected parameters and categories, with the median of each distribution shown as upward triangle. Attacker/defender refers to whether the player is in possession of the ball when dribbling, whereas back/midfielder/forward refers to the player positional role within the team’s lineup: (a) attacker aggressiveness \(\beta _a\) comparing when the player in possession is either a forward or a midfielder; (b) defender hesitance \(\beta _d\) comparing when the player in possession is either a forward or a midfielder; (c) attacker aggressiveness \(\beta _a\) when the player not in possession is either a forward or a back ; (d) defender physical exertion \(\alpha _d/\tau _d\) comparing dribbles executed by forwards when the player not in possession is either a back player or another forward; (e) defender hesitance \(\beta _d\) comparing when the dribble started from either the flanks or the center of the attacking third; (f) defender hesitance \(\beta _d\) slicing the player in possession between elite and non-elite dribblers.
