Balance is key in anything you do.
If you watch the Hawk/Kenny debate you'll notice that Hawk mentions multiple times that there will be a time and place for sabermetrics in baseball but only when more categories can be quantified.
Yes I know that they are already here to stay but I never thought anything Hawk said was so extreme or radical. Just an old school approach.
I think we could look at it like this: Kenny Williams used TWTW approach to help bring us a world series trophy by getting rid of guys like Carlos Lee and bringing in guys like Carl Everett. "Grinders" as they were called back then. Nothing novel about it, just a clever name given to it by Hawk.
