As a data-driven analyst raised in Brooklyn among mathematicians and basketball fans, I watched PSG exit Parc des Princes not with anger—but with quiet dread. The numbers didn’t lie: Montpellier’s 0-1 loss to Botafargo wasn’t luck; it was baked into the model long before kickoff. B-group dynamics, Bayesian probabilities, and real-time play logs revealed this outcome hours ago. This isn’t fandom. It’s forensic insight.
