While I think BTV overvalues Duran (46) and undervalues Paredes (12) I don't think 3 years of Duran is equal to 2 years of Paredes.
Yes, we are "desperate" for an infielder, but HOU is desperate for an OF'er.
If we trade Duran for Paredes, I'd want 2 from this group: B King, Sousa, Abreu or their catching prospect Janek. (Maybe just one and some decent prospect.)
