I don't have much of a problem with the theoretical foundation of WAR. But I don't like the defensive metrics currently incorporated into the calculation.
There's also the danger of dumbing down an understanding of the game by resolving a complex calculation into a single cardinal number, which I find troubling. After all, an understanding of the number system is orders of magnitude more ubiquitous than being able to look at a hitter's build and stance and having a good idea of where his holes are.
Both of these. I like WAR (even though I have an elementary understanding of it) as it is kind of a nice quick reference to see how well a player performs against the "average". I can just think of some subtle instances* where commen sense and WAR may butt heads. Like I said earlier though, I think it is a very useful metric.
*Some instances that come to mind immediately (and I'll probably get myself into trouble here as I don't have a high level of knowledge on WAR and all of it's individual parts):
DEFENSE:
- In regards to the defensive metrics, lets say an OF'er always dives for the ball no matter score, circumstance, etc. He may end up having a better "zone rating" than a smarter OF'er who knows where and when to pick his spots (so as not to allow a double). Obviously, we all know that making a diving attempt usually doesn't end up in an error when it's not caught, but it may end up costing an extra base or a run later down the road.
- Errors, sometimes a player will go out of his way to make a great play (say the score was 10-0 ) that he'd normally eat (i.e. - a squibber down the first base line with a fast runner at the plate) in order to preserve a shutout, a no-hitter, or a perfect game for a pitcher, but his throw goes into the 1st base stands.
PITCHING:
- A pitcher (I remember Jamie Moyer most recently when he was with the M's) might go more innings/outs than he should in a lopsided loss or win, when normally in a close game they'd be yanked, but they're going as long as they can to save the BP.
- A pitcher who knows a person has ownage on them, so they do an unintentional/intentional walk to the player to pitch to somebody less threatening, but their WHIP goes up.
OFFENSE:
- A guy goes for a stolen base in an unwise situation (say, down by 3 runs with nobody out in the 9th inning and only him on 1st base) and actually makes it. It helps his stats at the year end, but would probably be scolded once he got back to the bench.
Obviously, these are all outliers (in some cases, pretty extreme), but I can just imagine a huge majority of players in the future playing the game for statistics instead of wins. Perhaps that time has already come though and I'm just too foolish/blind to see it.
