I'm not knocking Schafer's defense, but I think the separation may be more than you think. Gomez is currently among the MLB leaders in most sabremetrics measuring defense. http://www.fangraphs.com/leaders.aspx?pos=all&stats=fld&lg=all&qual=y&type=1&season=2013&month=0&season1=2013&ind=0&team=0&rost=0&age=0&filter=&players=0&sort=24,d That and he's signed thru 2016 at a reasonable price considering his defense props up whatever offensive struggles he may incur. I was against the extention, admittingly, but at this point this is looking like a genius move by Melvin. First off, that is an extremely small sample to use. I am not arguing Gomez isn't a fantastic defender. He is. However you need to take at least 3 full years of defensive metrics then probably regress it a bit to get a good feel for what a player can do. That still leaves Gomez as a very good defender. You can't just ignore last year where he posted a 6.9 UZR/150. He is probably around his career 15.5UZR/150 minus a little regression. If that leaves Gomez as a 14 UZR/150 defender I would put Schafer around 12UZR/150.(honestly I would probably cut the runs by half) Not a full win on defense and probably not even half a run on defense. We need to trade somebody if we expect to get better and a guy who has a pretty solid backup and hasn't killed much of his trade value is the perfect guy to trade. Schafer + prospects + money would probably help our team more than letting Schafer sit the bench while we pay Gomez.
