Thanks for your advice on mine.
Like the guy above me said, you're missing that one front line starter. Now you have to ask yourself, "what do I have on my roster that can get me one?"
Well, K-Rod could, but it would leave you weak at closer. Vlad could, but I don't think your OF could absorb that, either. Hanley probably could as well, but that would leave you very weak in SB.
The next best thing would be to pair Cordero along with Cain for a guy like Sabathia, Dice-K, or somebody along those lines. I don't see you getting a guy like Oswalt, Carpenter, or Webb without taking a big step down in another category, so I'd try to get a SP that's maybe one level down from those guys.
