  In contrast both to formalists who see sport as constituted by rules only and conventionalists for whom sport is constituted by rules and conventions, broad internalists maintain that sport is constituted by rules, conventions, as well as underlying intrinsic principles (Russell, 1999; Simon et al., 2015). According to Robert L. Simon, one of the pioneers of this view, ‘broad internalism claims that in addition to the rules of various sports, there are underlying principles that might be embedded in overall theories or accounts of sport as a practice’ (Simon, 2000, 7). Intrinsic principles are key for broad internalists, as they provide the foundation for interpreting or understanding sport practices. Such principles are ‘presuppositions of sporting practice in the sense that they must be accepted if our sporting practice is to make sense or, perhaps, make the best sense’ (Simon et al., 2015, 32). Formalists and conventionalists fail to give due recognition to the idea that rules and conventions must be interpreted and applied so as to respect and promote normative principles that determine the point of the practice.
