"WAR Hates Sluggers
One of the things which advanced stats should be applauded for is the extent to which they’ve decreased the fetishizing of the homerun and raised awareness of all-around contributions. Jonah Keri and Dave Dameshek debated the relative merits of Willie Stargell and Tim Raines this week, largely based on the fact they had identical career WAR totals. Dustin Pedroia has a real shot at his second MVP, despite the fact that his “traditionals” (.309 AVG, 85 R, 18 HR, 74 RBI, 25 SB) are basically the same as Melky Cabrera‘s (.303, 83, 17, 79, 17).
However, one can’t help but notice that a cross-section of the most intimidating hitters in the game are treated with relative disdain by the metric. It doesn’t like them because they play first base or left field (or DH), which aren’t scarcity positions. It doesn’t like that they are fat and slow.
While I understand that everybody would love to have Chase Utley or Troy Tulowitzki, a middle-of-the-order hitter who makes big contributions in the field and on the basepaths, as well as at the plate, the fact remains, building a lineup without a slugger (or two) is like building a mall with seven Sunglass Huts and no department stores. A few sluggers are swift, slender middle-infielders. Most of them aren’t. To paraphrase Reggie, there are lots of drinks and precious few straws. If you get left without one, no amount of Range Factor, WHIP, or baserunning acumen can save your season. Just ask the Padres, or the Mariners.
Yet, we misuse WAR to insist that it’s better to have Ian Kinsler than Miguel Cabrera or that Peter Bourjos is as valuable as Prince Fielder or Mark Teixeira.
We’ve struggled to understand and statistically represent the effect hitters have on one another. Would Nyjer Morgan be hitting .306 if he wasn’t batting directly in front of Ryan Braun and Prince Fielder? (WAR suggests, by the way, that Morgan has been more valuable on a per game basis than Fielder.) Morgan is taking free passes this season at only about half his career rate. Has he become less patient? (On the other side of things, Adrian Gonzalez‘s career OPS is fifty points higher when the pitcher is throwing from the stretch. He’s enjoyed that situation in 52% of his plate appearances in 2011.)
While I admit the difficulty of building a model that accounts for the effect a pairing like Braun/Fielder or Pujols/Holliday has on the rest of the lineup, this is one area in which I find the conventional wisdom to be irrefutable. While I applaud WAR (and other metrics) for aiding in our appreciation of defense and baserunning, it’s beyond asinine to conclude that Ellsbury is twice as valuable as Fielder. Too often WAR is used as a means of comparing oranges to apples. One of the things that makes baseball great is the diversity of the fruit basket. WAR give incredible weight to scarcity of shortstops, but no weight to the scarcity of pitcher-intimidating, strategy-altering cleanup hitters, which I see as a form of reverse discrimination.
These are not the last of the problems. WAR evaluates catching using only the ability to control the running game. There is abundant evidence that certain park factors have not been sufficiently accounted for. I’m not arguing, however, that WAR should be completely discounted. As yet, it is probably as good a singular statistic as is widely available. But, WAR is not a debate-ending statistic, especially for single seasons. Even WAR’s adherents, like Dave Cameron, generally admit the margin of error is at least 15%. When we stubbornly suggest that 0.5 WAR means anything, we are grossly exaggerating the statistic’s accuracy, even according to its creators. It remains true that any reasoned discussion of an individual’s contributions still requires analysis of the various components that go into WAR, as well as several that don’t, and, as such, subjectivity reigns.
Statistical elegance is elusive. Variables get short shrift or go unaccounted for entirely. Results yield unintended consequences. Misunderstood data is misrepresented and polemicized. In the words of Tolstoy: WAR makes fools of us all.
