I agree completely. I lived in the DC area for many years. Most of my family are die-hard Nats fans. But I think a big, and I mean big problem with the Nationals, is that they, their fan base, and their media, think and act like they're much, much better than they actually are.
Like you said, they've had tremendous talent for years. Arguably one of the widest and longest lasting championship windows in sports, let alone baseball. One of the weakest divisions in baseball. And they've done nothing with it. Zero playoff series wins, let alone a pennant or WS.
But if you listen to their TV guys, or the DC media, or their front office, (I used to listen to Rizzo's weekly bit on the sports radio), you'd think they were the 27 Yankees the way they talk and act, instead of arguably the most overrated and underachieving team in baseball the last few years. It's incredible how this team, with the talent it has, has found so many ways to lose in the postseason, esp. at home. Rizzo for all his accolades has yet to make a bold move or acquisition at a trade deadline to get them that final piece...or bottom line to put a team together that can win something in October.
Now that other teams in the division are getting better, their road is getting harder and will continue to do so. I don't think rallying to beat the sad-sack Marlins is going to turn their season around. They have too many other issues ongoing. And it's sad cause with them hosting the ASG, all the talk will be rightfully how Harper doesn't deserve to be there....
