I'm not sure if you'd consider Derrek Lee or Matt LaPorta as upgrades.. if you do, I'd be willing to talk
Tornon, I sent you an email before I saw your message here. Just ignore the email, we can talk here. As I said in the email, I'd be looking to add a good OF in there (say Choo) and Loney for a sweeter return of Dunn.
EDIT: After thinking for half a 2nd, there's no chance in heck I trade Loney and Choo for Dunn. The OF would have to not be as good as Choo. But still, something along those lines. My OFers are: Choo, Bourn, McCutchen, DeJesus, Austin Jackson, Chris Carter (Oak, not NYM), and Abreu.
