Jacob deGrom, Cooperstown, and the Abstraction of Greatness

I’m a big believer in the value of WAR as a statistic. Like any summary stat, WAR is notably imperfect, with its nods to pragmatism, compromises made on philosophical grounds, and the necessary inclusion of many components that are just damn difficult to quantify even if we have a basis to think they’re important. Still, like all good models, even if WAR isn’t right, it can be useful. It gives us a broad estimate of a player’s overall contribution to winning baseball games, and almost certainly provides a far better conception of which individual actions lead to wins than generally existed, say, 50 years ago. But when we’re talking about whether a player is a Hall of Famer, a more malleable concept than what wins the most games, is WAR the right measure to look at? When I think about this question, four people instantly come to mind: Jacob deGrom, Miguel Cabrera, Jack Morris, and Wolfgang Amadeus Mozart.
Since FanGraphs is a website dedicated to baseball, we’ll start by talking about Mozart. Even people who don’t really listen to classical music, and thus couldn’t tell Gustav Mahler from Rick Mahler, would almost certainly count Mozart among the greatest composers of all time. Why? Well, the first part is obvious: because of his body of work as a whole. But what aspects of that work make him great? I’d submit that it’s the quality of his best compositions, rather than the massive volume of work he produced, that pushes him ahead of his peers.
Mozart is a legend because of his greatest works, such as his last three symphonies, his late 1780s/early 1790s run of operas, and the latter half of his piano concertos — and I could go on! But he also wrote a lot of stuff that just isn’t that good. He was a musical prodigy, but almost all of his early work is interesting because he was very young when he wrote it, not because of its own merits. Composers have always had to pay the bills, and Mozart wrote a huge amount of what was more or less intended to be pleasant background music, no more compelling than the peppy ukulele and xylophone music that seemed to be in every Kickstarter video in 2017. If the hundreds of examples of such work were to simply blink out of existence because someone got a hold of the Infinity Gauntlet, it would change nothing about Mozart’s greatness. Those compositions had value to Mozart in that they enabled him to write the good stuff that is worth remembering, but he’s great because of his peak. Read the rest of this entry »
