If they have another couple postseasons like their most recent ones, the Nationals. Never made it past the divisional round in 4 tries, and three of those Ls came in Game 5's at home, all in excruciating fashion.
Crazy that a team with that kind of core (young, at that) hasn't really gotten close to a WS yet.
Most psychologically damaged player I’ve seen was Chuck Knoblauch.
My goodness he really struggled with his confidence and those throws.
