Gigantic lack of supply versus demand. You have Greinke on a tier by himself and that's if the Angels don't lock him up before he hits the market. After that, it gets murky. You have Peavy, Sanchez, and Jackson, that appear to me as the next tier. Followed by McCarthy and Marcum, due to injuries. Then it's upside versus risk in guys like Liriano and Santana. And the cagey vet group of Dempster, Kuroda, Lohse, Saunders, and Blanton. I'm not sure where you slot in a Villanueva, but he's got to be somewhere in the middle of that, if not higher.
