What do we have here? For an explanation of this series, please read this introductory post. As noted in that introduction, the data 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. 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.
Dave’s hit you with the introduction, so it’s time to begin this series in earnest. And we’ll begin, as we always do, with the catchers, even though catching might be baseball’s most mysterious position. For an idea of the spread of what you’re going to see — which is more important than the rankings themselves — here’s a graph with green in it:

You’ll notice there’s a big gap between first and second. It’s a gap of 1.2 WAR. That’s as big as the gap between fifth and 24th. Let there be no question: by our system, there’s a clear first place, looking down upon the rest of the landscape.
But of course, our system isn’t all-encompassing or perfect, and not just because the projections are arguable and the playing time is arguable too. There are just things about catching that aren’t included, one invisible one being game-calling, and one visible one being pitch-receiving or pitch-framing. You’ve seen the pitch-framing research, and you’ve seen some of the numbers it suggests. Including those numbers would shake up these rankings. The market doesn’t seem to believe too heavily in the numbers, and conversations I’ve had suggest people in the game think the numbers are too extreme, but there’s little question there’s some kind of skill there, and so catchers should receive at least partial credit. I’ll take care to talk about pitch-framing below, for catchers where it makes sense. You can mentally shuffle that information into the rankings. Now it’s probably beyond time to proceed, from the top.
