As a Chicago-based NBA data analyst with a soft spot for the Bulls, I’ve studied fandom like player tracking data. In this piece, I explore why millions—like that fan from South Africa who fell in love with football at the 2010 World Cup—follow the sport without a home team. Using behavioral patterns and emotional attachment models, I break down the psychology of 'player-led fandom' and how it’s not just common—it’s statistically significant. If you’ve ever cheered for a club because of one star, this analysis is for you.
