NBA Player PER Report

PER is one of the most cited basketball statistics in fan and media contexts, yet its construction and interpretive limits are rarely explained clearly.

The report clarifies PER's construction and highlights systematic biases that affect certain player roles, providing a clear guide for analysts and fans using the metric.
