SP

[Cardinals]

After a couple of deals, looking to either 1.) add a SP for next year, 2.) boost SP prospects, or 3.) upgrade myself slightly at SP.

Obviously, some of these guys are more costly than others, and a couple of these guys (Byrd, Huff) I'd only be looking for a mildly interesting prospect for. But here's who I'm willing to discuss:

Byrd
Huff
Frankie Francisco
Gregerson
Robbie Grossman
David Murphy
Joe Nathan
Edinson Rincon
Gaby Sanchez
Jake Westbrook
Eric Young Jr
Brent Keys
LeVon Washington
Edwar Cabrera
Blake Beavan
Yu Darvish (upgrade only)
Daniel Bard (likewise)
