I'd take Zimmerman over any of them. UZR disagrees, but I don't know where anyone falls out of the top three (Feliz, Rolen and Ramirez). Zimmerman seems like he's fantastic at third and his true talent may well be up there. I haven't watched him play much at all, for whatever that's worth. Players can definitely have peak (outlier, career, whatever) defensive years, and I doubt that the GG voters ever get a handle on that.
