To wrap up, this post hinted that the ball and the player in possession of it seem to be relevant DoFs to take into consideration when trying to understand (scientists) and train (coaches) the system under study (i.e., soccer). The take-home message, thus, is to warn coaches and scientists that their choice of DoFs, if not appropriate, can slave their theory of the game (scientists) or their playing style (coaches). In other words, when a scientist’s choice of DoFs does not seem to be right, then, their theories become slaves of the output’s interpretation from mathematical modeling. In the same way, if a coach does not manipulate the right variables in each training drill to constraint the team behavior to the desired team’s playing style, then, their playing style becomes slave of coaches’ misinterpretations of the variables of the game (DoFs) to achieve a desired playing style.
Next month’s post will address the ontology of soccer to answer questions such as: What relationships among DoFs hold the systemic nature in soccer? What is the system in first place? and others of similar nature.
