I understand that, but the way I see it you want your best fielders at each position. If Espinosa would be a better fielding SS than Desmond, they should switch, regardless of whether that would mean the production levels were skewed.Exactly my point.
I want Espinosa at SS because he has the potential to be a gold glove SS. Only the Nats are dumb enough to move a Gold Glove caliber SS so they can leave SS who is on pace for the most errors of any player since the Strike
