I could say the same thing about his "data". WAR is only one metric. There are others. For example, his OPS+ is down to 94, BELOW average. His OPS is .709, also BELOW average. Since the ASB his BA is .188 and his OPS is .491-in 137 PAs, not a small sample. I wrote earlier that I thought this would happen as he got tired from the long season.
In a vacumn given his defense it might be tolerable, but with so many other guys falling off the cliff (Narvaez, Gonzalez etc) he's a liability. But as I said, cheer up! He's not going anywhere. But he remains fair game to be targeted for criticism just as the Sox announcers have done ("we gotta get him going" etc). It strikes me as a bit blind for ostensibly knowledgeable posters not to see that.
