Actually, at least 12 catchers will put up more than 2 fWAR this year....so it's more like 10 or so that are good or better, 5 or so that are meh, and the rest. Unfortunately, Castro is in the rest category (though fWAR does not yet include framing). There weren't many good options. Hopefully, Garver will hit like he has in the minors, and be ok on defense, and he'll be that guy that gives them a top 10ish catcher. We'll see if he's even given the chance.
