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. If you think we can do better at 2B than Desmond, then we should trade him and acquire that better 2B.
Espinosa is a lot better defensively at SS than Desmond.
Exactly my point.
