If you, as a fan, know Swihart needs a lot of work defensively, what makes you think other organizations don't? They scout these guys year 'round, and have a better sense of a guy's strengths/weaknesses and value than we do. Trading him when, even with his prospect pedigree, interested teams could say "well sure, but you can't even guarantee he'll stick at catcher" is a huge negotiating ploy. Seeing how his defense evolves is the avenue to getting maximum value in his case.
