Carlos Carrasco for Mark Teahen?
There's an interesting discussion of this very question here, and I thought I'd take the pulse of the TGP readers.
My personal feeling is that if Teahen's shoulder is 100% healthy (he had off-season surgery on his labrum, I believe -- a particularly worrisome bit of anatomy), I'd do this in a NY minute and I'd sweeten the deal if needed.
Teahen is an above-average 3B, both offensively and according to scouts and stats, defensively as well, right now. He's an inexpressibly vast upgrade over Nunez, and a big step up over Helms as well. And he's young so he's likely to get better, and four years from free agency.
What do the rest of you think?
