One analysis identified the Nationals as the most challenging team to support in sports. That’s because they are atrocious by any marker. Yes, they recently won a World Series but their reaction made it appear to be a mistake. They instantly posted the worst three seasons after winning a title.
Meanwhile, they lost the most games in franchise history as well as the worst run differential. We’re only talking about their recent history here because things become even worse. Before their World Series win, the Nationals were more than an embarrassment to MLB (via Washington Post).
