There's something to be said for versatility (and for some players) that development comes later in their careers. The New York Yankees have several versatile pieces on their roster. Jose Caballero can play all over the infield as well as the outfield. Ditto, for Amed Rosario, who came up as a shortstop and learned how to play second base, third base, and the outfield corners as he tried to revive his career after busting as a former New York Mets top prospect.
The appeal of trading for Ryan McMahon came with his glove. While the Yankees were always hoping his left-handed bat would play up in Yankee Stadium's friendly confines, it was the Gold Glove-caliber defense that was the top selling point.
