Jaffe WAR Score System

The Jaffe WAR Score System, commonly abbreviated JAWS, is a sabermetric baseball statistic developed to evaluate the strength of a player's career and merit for induction into the Baseball Hall of Fame. Created by averaging a player's career WAR with their 7-year peak WAR, its "stated goal is to improve the Hall of Fame's standards, or at least to maintain them rather than erode them, by admitting players who are at least as good as the average Hall of Famer at the position, using a means via which longevity isn't the sole determinant of worthiness" It was devised in 2004 by Jay Jaffe of Baseball Prospectus.
