Which of these 4 guys would you want to have for the rest of the season?

Kelvim Escobar
Tim Hudson
Ted Lilly
Jeremy Guthrie

All these guys are on a team I'm looking to make a deal with. They would join Sheets, Shields, Zambrano, Hill, and Gorzelanny in my rotation. I also have Harden but I'm not going to expect anything, just take it as bonus if he does well.

Also, what type of SP would you expect in return if you were trading Francisco Cordero straight up for that SP?
