Ok, so the Globe's Nick Cafardo is floating trade talks with the Rockies (initiated by the Rockies). The Rockies are seeking what looks like Hansen for Helton (and they will pay a big portion of Helton's contract). Why wouldn't you do this? Hansen more than likely won't make the big league roster (at least to start the year), and he isn't going to be the closer (even late in the year). The Sox lineup would be devastating.
Also, you could then try to move Lowell and move Youk back to third.
Think of the lineup:
Of course, Helton's power numbers are way down, but he'd be your number 6 hitter and you'd be getting him for an unproven pitcher.
The down side is that your defense in the infield really isn't very good (minus Helton). Youk is a downgrade at third from Lowell, Lugo (anyone) is a downgrade from Gonzalez, and Pedroia (well, we haven't seen much of him)...
Anyway, I doubt (*seriously doubt) that this is much more than Cafardo trying to stir something up during a very quiet on the baseball front month. But it is cool to think about...sort of...
