If you haven't already checked them out, Dan Szymborski released his 2014 ZiPS projections for the Yankees over at FanGraphs yesterday. Projections, in any system, always have to be taken with a big grain of salt, but the ZiPS method has been the most accurate the last few years and is at least a decent way to gauge the team's current talent level.
Definitely click the link and peruse through in greater detail when you get the chance. If you don't have that chance right now, here's what you need to know. ZiPS isn't a fan of the current infield, projecting just 1.7 WAR from Mark Teixeira (in 356 PA), 0.4 from Derek Jeter (in 325 PA), and 0.2 from the newly acquired Brian Roberts (in 215 PA). It does project Jacoby Ellsbury and Brian McCann to be the 2 best players on the team in terms of WAR (no surprise there), and also expects somewhat of a bounce back from CC Sabathia and another solid season from Ivan Nova.
There's a lot to sort through there, but it basically tells us what we already know. The Yankees still need help everywhere.
