Nationals won 98, 86, 96, 83, 95, 97 games before falling to 82, so last year was a severe under performance, not an indication of their basic talent level.
Phillies have won 63, 71, 66, 80, 81 the last five years.
We're not one or two players from the WS.
Teams that tend to make playoff runs with marginal records tend to be good teams that get off to bad starts or struggle during the season, but put it together for the playoffs.
Even the 2008 Phillies, 86, 85, 88, 85, 89, 92, a good team on the field that struggled to put together a pitching staff for the regular season, then Hamels, Lidge and Madson put them over the top - Lidge had an unrepeatable season. The trade for Blanton was the key move, but this was always a team that was a couple pitchers away from a run.
