How Did Previous Andrelton Simmonses Age?
Last night, the Braves traded Andrelton Simmons to the Angels for Erick Aybar and a couple of pitching prospects. While it’s likely that Atlanta’s staff made this deal primarily to acquire Sean Newcomb, a big left-hander with high-end stuff and strikeout rates to match, I think it’s fair to categorize this return as surprisingly light. Newcomb is brimming with upside, but he’s still a pitching prospect who hasn’t yet figured out how to throw strikes on a regular basis, and has made all of seven starts above A-ball. He could figure things out and become an ace, or he could go the Archie Bradley path, where the stuff declines before the command gets better, and the Braves could end up with little to show for trading away the best defensive player on the planet.
But therein lies the rub. While everyone agrees that Simmons is a great defensive player, the Braves don’t appear particularly interested in betting on elite defenders aging particularly well. They balked at Jason Heyward’s salary requests in long-term negotiations, then traded him last winter, rather than keeping a 25 year old star outfielder around as a core building block. Now, for the second time in as many years, the Braves have traded elite defense in a young player for pitching potential, seemingly believing that it is easier to find a good defender with offensive question marks than a power arm who racks up strikeouts.
And as I noted yesterday, there might be some logic to that idea, given that there’s evidence that defensive skills peak earlier than offensive skills. The athleticism that allows a player to make plays that his peers can’t make is more vital for defensive value than hitting skills, and it’s possible (and probably even likely) that the Braves saw the potential for Simmons to lose value in the near future, if his defensive value dipped and his offense didn’t improve to offset the decline. So, it’s probably worth exploring how previous elite defenders have aged, and see if we can find support for the idea that the Braves were selling high before a coming decline.
