As a Chicago-based sports data analyst with a Northwestern applied math background, I’ve tracked 2008–2023 NBA offensive patterns using real-time visualizations. This piece dissects why elite players’ three-point attempts collapse under defensive pressure—not due to talent, but flawed tactical execution. My model reveals hidden breakdowns in screen-side spacing, mask coverage, and late-clock decision fatigue. Data doesn’t lie. And this? It’s not magic—it’s metrics.
