While Bob Nightengale of The USA Today has reported that every member of the Chicago Cubs roster is on the table for trade, this does not mean Starlin Castro is going to be traded. He is under Cubs control until 2017, and his future appears to be very bright. The amount of prospects it would take for the front office to even discuss trading the budding superstar would be prohibitive for any team to go through with.
Three players should be moved if 2012 is a casualty of a massive rebuilding effort. The value of these players in a soft free agency market is undeniable. The prospects Chicago could receive in return would immediately improve the depth and quality of a farm system desperate for both.
Carlos Marmol, Matt Garza, and Sean Marshall should be moved this offseason to prepare the Chicago Cubs for the future.
