  Deep conventions do not relate to problem solving and coordination. Rather, they are ‘normative responses to deep psychological and social needs for playing sports’ (Morgan, 2015, 39). Put differently, deep conventions shape sports into the various historical and social forms they have taken. For instance, the principles and ideals underlying the amateur view of sport, according to which participants engage in the game chiefly for the love of it, are deep conventions. Thus, a sport’s deep conventions determine the point of that sport and provide a rationale for playing the sport in a specific way by establishing what counts as normatively intelligible and justifiable within that sport. For example, amateur athletes often view sport as a perfective enterprise pursued for its own sake. They play sport for the love of the game not for instrumental benefit. The amateur’s emphasis on the intrinsic value of sport contrasts with the professional’s view of sport. For professionals, sport tends to be viewed as a serious, instrumental occupation, that is, a means to earn a living (Morgan, 2015, 40–41). Thus, amateurs and professionals evaluate differently practices such as training, doping, and strategising. While professionals embrace conduct that increases their chance of victory, amateurs are often more discerning, rejecting practices such as professional coaches and strategic fouling on the grounds that they are detrimental to the emphasis of the appreciation of the practice itself, not the instrumental goals achieved through it.
