If I’m going to misuse a statistic to prove a point, I tend to think I should let my readers know exactly what statistic I’m misusing. That’s why I put a small “f” or “r” before referencing the wins above replacement acronym.
The all encompassing WAR metrics used by FanGraphs and Baseball Reference, while based on the same principle, have subtle differences, most notably in how they measure fielding for position players and in using pitcher controlled outcomes or runs allowed for evaluating pitchers.
Nonetheless, the two metrics, along with WARP from Baseball Prospectus, are generally accepted as the go to measuring stick for commoners like us who don’t have access to the calculator benders in Major League front offices.
Well, there’s a new tool in town, and its creators made the unfortunate decision to put a “g” prefix in front of it, meaning that baseball and gWAR will now be eternally linked.
For those not in the know: 1) Be proud of yourself; 2) Count yourself luck; and 3) Gwar is a band that … well, they dress up … and they’re
best most safely described by their Wikipedia page:
Gwar is a satirical heavy metal band formed in Richmond, Virginia, United States, in 1984. The band is well known for its elaborate science fiction/horror film inspired costumes, obscene lyrics and graphic stage performances, which feature humorous enactments of politically and morally taboo themes.
For more on gWAR and not Gwar, check out the introduction at seamheads.com. It reads to me as though the new metric will judge pitchers in a similar fashion to rWAR and use an entirely different system to judge defense. Tom Tango and his following are discussing it over here.
