What do we have here? For an explanation of this series, please read this introductory post. As noted in that introduction, the data below is a hybrid projection of the ZIPS and Steamer systems, with playing time determined through depth charts created by our team of authors. The rankings are based on aggregate projected WAR for each team at a given position.
Yes, we know WAR is imperfect and there is more to player value than is wrapped up in that single projection, but for the purposes of talking about a team’s strengths and weaknesses, it is a useful tool. Also, the author writing this post did not move your team down ten spots in order to make you angry. We don’t hate your team. I promise.
As we kick off the 2015 Positional Power Rankings with catchers, let’s start with a chart of the projected WAR totals, and…

…and good lord, Giants and Diamondbacks, for two entirely different reasons.
Immediately obvious: Buster Posey isn’t just the best catcher in baseball, he’s the best by a considerable amount. Also equally obvious: It’s going to be a really, really long season in Arizona. In between, you’ve got some pretty clear tiers of 4-6 teams apiece, and that’s far more important than the actual rankings themselves. After the Giants, the next 10 teams break down easily into two blocks, and then beyond that, starting with the Mets at No. 12, there’s a soft decline from “acceptable” to “poor” to, well, the Diamondbacks.
Remember, please, that there’s just not a lot of meaning in tenths of a point of WAR, so while (for example) we have the Mets and Rays separated by nine spots, they’re only 0.4 WAR from one another. Remember, also, that our WAR formula doesn’t currently account for pitch framing, which has been pretty well acknowledged here and elsewhere as being a real thing that exists. You’ll just need to mentally account for additions (or demerits) for those catchers well-known to be valued (or avoided) based on that skill. Read the rest of this entry »
