Creativity in sport is often framed as a rare trait linked to performance outcomes and match-winning moments. This chapter challenges such narrow perspectives by introducing the Situated Model of Creative Action in Sport (SIMCAS), a developmental and inclusive framework grounded in cultural psychology. SIMCAS conceptualizes creativity as a dynamic, relational quality of action that emerges through the interaction between individuals and their environment. The model outlines four interrelated dimensions—normativity, intentionality, materiality, and capability—that shape the affordances available to players and coaches in specific contexts. Rather than treating creativity as a performative end, SIMCAS positions it as a developmental means to enhance learning, wellbeing, and long-term engagement in sport. Drawing on empirical studies and practical examples, the chapter demonstrates how creativity can be cultivated through safe, playful, and autonomy-supportive environments that encourage exploration, risk-taking, and habit-breaking. By shifting focus from outcomes to processes, SIMCAS offers a conceptual foundation for designing and delivering creativity-nurturing practices in team ball sports. The model invites practitioners, researchers, and educators to rethink creativity as a shared, situated, and accessible resource for all participants—regardless of age, skill level, or position.
