The Yankees have made a lot of moves to improve their hitting and defense during this offseason. You know about all of those. But what cumulative effect have these moves produced? The following chart shows three different numbers by position: the fWAR produced by Yankees playing that position in 2014, the fWAR produced by the average major league team, and the Steamer projections for the Yankees at the position in 2015:
You can see that the Yankees project to improve in right field, shortstop, designated hitter and second base, stand pat at catcher, 1st base, center and left, and decline at third base. That all sounds reasonable to me.
You can really see how Derek Jeter and Brendan Ryan at short and Carlos Beltran, Alfonso Soriano and Ichiro in right and DH killed the Yankees last year. Just getting those positions and DH to replacement level would have put them in the playoffs. A 1-win projection player like Didi Gregorius doesn't seem so special, but he represents a 3+ win improvement over 2014.
