Masterson is an elite pitching prospect already? Dye makes us world series favorites. Prospects are questions; banners are there forever. Now, there are some prospects that I wouldn't trade, but Masterson is probably 4-ish years away from being a major league pitcher. He may not even have a spot in the starting rotation when he's ready. If you can trade Masterson and get a world series in return (or a very good shot at one), it's worth it.
