I think there are many flaws in WAR, enough to render it not worth serious consideration in and of themselves. Many of those flaws have been detailed here very well by others. But I find the idea of "positional adjustments" so extremely wrong, at such a basic level, to render the entire premise faulty in and of itself. Ignoring the defensive issues, WAR purports to identify the worth of a given set of offensive outcomes, and translate those outcomes into wins. Fine. But then we're asked to make the leap of logic that the exact same outcomes are somehow worth more wins if performed by someone who lines up at SS, rather than 1b. If we've identified the worth of a given offensive performance, and translated that into a number...what possible difference does it make where that comes from? Do we put 1.05 runs on the board if a SS hits a HR, and .95 runs if from a 1b man? And yet a SS starts with a WAR advantage over a first baseman. Why? Every team has one of each in the lineup. Just because big offensive numbers are harder to come by from a SS doesn't mean they add up to more runs. Those big numbers are already included in the WAR total.
