Fans here might be overly optimistic about what the Nats could get by trading off relief pitchers this week. As a check, take a look at the players the Nats traded to get Melancon, Doolittle-Madsen, Brandon Kintzler, and Roenis Elias / Hunter Strickland. Hand or Hudson might return more like the Doolittle-for-Treinen deal, but, best I remember, Treinen was a failed starter who seemed to collapse when he had to pitch under pressure, making him a failed closer.
