IS IT WORTH THE EFFORT?
New paper to understand players and teams’ high-intensity efforts.
Estimation of the impact of a player’s run on his team’s possession value.
Developed with 500+ matches of tracking data of the big-5 European competitions.
Link: arxiv.org
We detect the players’ runs from tracking data and we contextualize them thanks to different layers of tactical concepts to better understand high-intensity efforts. Some of the concepts taken into account are the possession phases, defensive lines, and the attack/defense types.
Do teams with higher possession percentages run less? Do all players run in the same way?
We create team and player profiles that mix tactical and physical metrics derived from HI runs. As an example, we discuss the relationship between more ball possession and running less.
How much does a player depend on his speed to add value?
We present examples of how different strikers tend to do on-ball actions at different speeds. But we highlight those who rely on their HI runs to add value from those who are consistent in adding value at any speed.
What is the impact of the HI runs on the possession value?
We aim to distinguish the players who run more from the ones who run better by estimating the impact of their high-intensity runs on the increase in their team's possession value (via EPV).
We see this work as a new path of research thanks to the impact on the different profiles of experts in a soccer club. From players and coaches to scouts and even physical coaches.
