A prospect is just that, a prospect without any assurances that he will do well at the major league level. I think back to that cover of SI that featured Paul Wilson, Jason Isringhausen and Bill Pulsipher as the new Seaver, Matlack and Koosman. We saw how that turned out. That said, I like the idea of interjecting youth into MLB team. They play with energy (usually) and an eye towards the money as a free agent. From the Yanks perspective, if its near the All-Star game and you are in the race, then you have a better perspective on the guys in your system, and how the season is going for potential trade targets.
