I hate to name the highest-profile guy, but I think this year's key Met may be David Wright � a broad and relatively flat range of possible outcomes, high stakes in him being the number-three hitter, and little in the way of alternatives (if Wright goes down again, it's either Campbell or Flores with Tejada moving to short). David Wright: my key Met for 2015. He's the center pole on the tent, and if that holds, the ones around the outside won't be as prone to collapse. Any list of the keys, though, has to include Flores. Beyond them, I see Duda and Mejia. Least key player is probably almost always the backup catcher. Sorry, Anthony. Other projected benches (Niewenberry and Campjada) share this fate. Also not a key Met: Daniel Murphy. He's got a range of outcomes stacked toward the middle, not a necessarily key part of the offense or defense, and meaningful alternatives are in place. I'd say that Colon isn't key, and Gee hardly looks to be a key if they can't find a job for him.
