Who cares what another team's fan thinks? I can form my own opinion about this team's shortcomings. Just because I watch the braves play occasionally doesn't make me the expert to go to their board and tell them about it.
Obviously, enough posters on this board care what other teams' fans think.
And you don't have to be "an expert" especially since nobody here is an "expert" about the Nats. Observations from the outside can be most helpful. It's called "criticism."
