This article draws on Game Sense pedagogy and complex learning theory (CLT) to make suggestions for improving decision-making ability in team sports by adopting a holistic approach to coaching with a focus on decision-making 'at-action'. It emphasizes the complexity of decision-making and the need to focus on the game as a whole entity, where players, individually and collectively, attempt to manage disorder in the face of an opposition. It rejects the complicated, mechanistic approach to learning and cognitivist views that dominate the literature on decision-making in team sports that see it as being a linear process of conscious thinking limited to the individual mind. It offers an alternative, holistic view grounded in a practical example of how this might be achieved in coaching rugby union football and theorized within a CLT framework. © 2012 © 2012 Taylor & Francis.
