I don't make that trade.
Dejesus and Thames are your most expendable guys though. I'd rather see you drop one for an Upton first. And Jose Lopez is certainly someone you could drop, too, for a 2B like Upton.
You'll need Swisher in that OF.
You're going to need more closers. I don't see having Meche, Suppan, and Billingsley.
Please post some FAs. You might be able to switch out 4-6 guys now to improve your team.
