Um, I don't think anyone is claiming that Span is blocking Parmelee. The whole point of trading Span has been: A. The Twins are rebuilding B. Span could have a lot of value on the trade market due to his skill set and team friendly contract. C. The Twins think they have a CF replacement (at least in the near term) for Span in Ben Revere. D. By trading Span the Twins can fill other areas of need (Starting pitching, MI) while possibly getting younger/cheaper. As finding someone to handle RF isn't exactly a hard proposition, if Parmelee can't handle it the Twins can continue to look for internal options for 2013 (Benson, Arcia, etc) or can go out and sign a veteran stop gap for a year to handle RF (Hunter?)
