I think, in general prospects are overrated, heck look at how US TWINS fans, we covet ALL our prospects, and some people say, dont trade any of them , that is crazy!!! Not saying you one of them, but i would trade a prospect for a chance to win a World Series than keep him and hope he makes us good later, later may never come...........again as i have said previously , this is not the year, but if it was, I would do something like your trade scenario for Greinke................and since you either didnt see my other post that was directed toward you, Carlos Santana, Dustin Ackley , and Jesus Montero were all ranked higher than any of the 3 prospects that were traded, and none of them are special, Santana may be close , but he is one dimensional...................So again prospects are just, like a box of chocolates, you dont know what you are going to get.
