Last summer, PointAfter revealed a new metric called Free Agent Quotient (FAQ) in an attempt to measure the future value of free agents. The sports visualization site, part of the Graphiq network, has revamped the FAQ formula to better account for defensive impact.
This year, PointAfter introduced box plus-minus (BPM) and value over replacement player (VORP) into the formula, which previously featured player efficiency rating (PER), win shares and age. We also distributed some weight away from PER, which tends to favor high-efficiency big men who can score the rock and rebound but don't add much value beyond that.
