Lets face it - you can postulate all you want about how many wins a certain player is worth and come up with formulas to show it. However, there's no way to actually show that those calculations are correct. Hell, not even statheads can agree which version of WAR is the best to use. If you (and not you specifically, but the pushers of the statistic) can't even agree on how it should be calculated, why should anyone view it as such a rock-solid method of player evaluation?
Furthermore, defensive metrics are so arbitrary that I have no faith in their ability to adequately judge the abilities of players in the field, or predict the outcomes even if they're good at judging how many additional baserunners a player allowed through fielding blunders or inability. Pitchers pitch differently when players are on base. Veterans are have more experience pitching under pressure. The quality of the pitching staff in general should greatly affect how damaging fielding errors are. How can WAR account for a mindset change in the same player based on the situation, or any other human element that doesn't show up on a stat sheet?
In 2009, Ben Zobrist's WAR was 8.6. Albert Pujols' WAR was 8.4. Are we to believe that Zobrist was a better player that year than Pujols? Chase Headley had a higher WAR this year than Cabrera. Should the Tigers be calling up the Brewers to deal?
I'm sorry, WAR doesn't pass the eye test for me. I'm not saying it doesn't have value, but people who want to make it the only stat that matters (and they're out there in droves) are misguided.
