Bill James Doesn't Like WAR

The baseball kind. A quote from Joe Posnanski's piece on the baseball stats guru (he hates that title) in winter, “Vanguard After the Revolution”:

Sometime in the last year I was doing some research that relied on these WAR systems, so I took a look at them, and … they’re not very impressive. They’re not well thought through; they haven’t made a convincing effort to address many of the inherent difficulties that the undertaking presents. They tend to get so far into the data, throw up their arms and make a wild guess. I don’t know if I’m going to get the time to do better of it, or if it will be left to others, but … we’re not at anything like an end point here. I assumed that these systems were a lot better than they actually are.

Will be interesting to see if this has an effect on WAR's sudden ubiquity. If it does, if James manages to diminish WAR, I say we send him to the Middle East.
