Should I do this trade? Fantasy Baseball?

This guy is offering me Prince Fielder ( I need a 1st Basemen, have Mark Trumbo), Jay Bruce, and Elvis Andrus. I have to give him Matt Kemp, Jose Reyes, and Colby Rasmus (He is a bench player I have a pretty solid outfield in Matt Holliday, Andrew McCutchen, and Matt Kemp) Should I accept this trade?
