For this post I was asked to take a look at every position and pick which team has the most overall talent if you look at the organization as a whole. So if a team has a strong shortstop at the major league level but no depth within the organization, it could come in behind a team with a decent shortstop but a couple of really good prospects at the position. So think of this as the sum of current MLB talent plus what's in the pipeline.
It's worth a reminder that strong depth at one position is a good way to fill holes via trades. Anybody saying too much talent at one position doesn't matter because you can't play three shortstops is clueless from a business and personnel standpoint. As a note: outfield and pitching have been consolidated because of how we calculate value at those positions.
The Yankees have more prospect depth at the catcher position than any other team, with Gary Sanchez a potential star if he can improve his receiving enough to remain at the position, while J.R. Murphy is emerging as at least a strong backup. Austin Romine should be getting regular playing time in the majors down the stretch, at least once the Yankees decide their playoff odds are too low to ... well, playing Chris Stewart isn't exactly pushing them toward the playoffs anyway, so why not just play Romine and see what you've got?
That said, the Pirates probably have more present value than the Yankees because of Russell Martin, with Tony Sanchez probably a solid major league backup and 18-year-old Reese McGuire among the game's top dozen or so catching prospects. There is so little catching in full-season minor leagues right now that you would be hard-pressed to identify 10 clear everyday starters without reaching down to short-season leagues.
