On Aug. 29, 2025, the New York Post reported that sports analysts have yet to establish a universally accepted statistic that accurately measures a coach’s impact on team success.
The article points out that, despite decades of innovation in player analytics, no comparable number exists to quantify the decisions, adjustments and leadership provided from the sideline. As a result, coaching performance remains largely subjective, relying on wins, losses and public perception rather than a single data point.
