It kind of depends on what "top prospects" means exactly, but I can't imagine giving up HJ Lee and Chirinos + pretty much anybody else as a good deal. If top prospects means JJax, Vitters, McNutt, etc., then it gets into the horrid trade range. Looking at xFIP, Garza hasn't been terribly impressive. He may outpitch his xFIP as he's done in Tampa, but he won't have the same level of defense playing behind him in Chicago that he's had in Tampa. Being any more than a 3-4 starter is unlikely, I'd think.
