We Need to Talk About Defense

Three whole days since this was published?? Come on, Baseball Think Factory, time to put aside your all-important OTP arguing and start thinking!

The reason that we have positional adjustments in WAR(P) is that we want to give a player credit for playing a difficult position. He might be an average defensive shortstop, but (we assume) if his team needed him to do it, he could be a somewhat above-average second baseman and a crackerjack left fielder. (Hanley Ramirez would like a word with you.) But if the sample that produced those adjustments is significantly biased and the main assumption—-that “defensive ability” is portable from place to place—-isn’t solid, then is that construct modeling reality or a convenient representation of what we thought reality was?
