Everyone on this board is a fan of this team as whole but whether someone understands it or doesn't, some people are partial to certain players and root for those players for a variety of different reasons. There is absolutely nothing wrong with that. I don't see why Yank fans and Card fans can root for the Jeters and the Alberts without criticism but a Nat fan can't root for a Church, Zimmerman, or Cordero?
The determination of "who earned their way" there is sketchy and fans usually see it at face value (stats). One has to also figure if that guy can keep those monster stats up, what are the chances he will get injured, etc. Some guys are put in a position simply because they can make that 162 marathon and fill a spot. Need to look at the big picture.
I know there are a few on this board who don't think Church "earned his position" but you know, I myself don't think Logan "earned" anything either. But they are both Nats, loyal so far to this team, so I can't really complain.
