Jaffe WAR score system added to Baseball-Reference.com

From SABR member Sean Forman at Baseball-Reference.com on November 19, 2012, with mention of SABR member Jay Jaffe:

Baseball-Reference.com has added Jay Jaffe’s JAWS system to our suite of Hall of Fame evaluation tools. JAWS appears on every player page.


The JAWS (Jaffe WAR Score system) was developed by sabermetrician Jay Jaffe — first at Baseball Prospectus in 2004 — as a means to measure a player’s Hall of Fame worthiness by comparing him to the players at his position who are already enshrined, using advanced metrics to account for the wide variations in offensive levels that have occurred throughout the game’s history. The 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.
