Besides the Kazmir trade, which was made by an interim GM who lost his job after 2 months, and the Bay trade in 2002, (the Mets, along with the Expos and Padres, traded Bay before he was seen as a top prospect) is there another instance of a traded Mets prospect making it big? No.
Carlos Gomez? Solid player, but traded for Johan Santana. Mets Win.
Lastings Milledge? No.
Damn player-centric usernames straight to hell.
