Many of us don't buy into the hype of these metrics - not because we are afraid of math - but because these metrics cannot explain what happened on the field that resulted in a particular game being won or lost.
These metrics have some utility when comparing players to each other, for instance when comparing players who play the same position, such as debating Sox left fielders over the years.
But ultimately, the game is played on the field, and no one watching the game gave a fat rat's *** what Scott Podsednik's WAR was; Sox fans always will remember him for his amazing World Series walkoff HR.
The universe is the practical joke of the General at the expense of the Particular, quoth Frater Perdurabo, and laughed. The disciples nearest him wept, seeing the Universal Sorrow. Others laughed, seeing the Universal Joke. Others wept. Others laughed. Others wept because they couldn't see the Joke, and others laughed lest they should be thought not to see the Joke. But though FRATER laughed openly, he wept secretly; and really he neither laughed nor wept. Nor did he mean what he said.
