Well, I've never been a fan of Jenkins. His results have never matched the hype, and now he's on the DL w/ shoulder soreness. I'd be fine with trading him.
I really don't want us to trade Rosenthal or Martinez. Wacha seems like he'll eventually be a solid #3 who can gobble innings, and that's a valuable commodity as well.
I think the organization would be well served to try and find Freese's replacement in the draft. If they want to try and package some of our pitching for a shortstop, great, but I don't see any long-term solutions that aren't major risks.
