I have been pretty much in the camp of not signing Fielder. I wouldn't be upset if they did without it impacting our core players especially Zimmerman. I think signing PF will not be a move being done in a vacuum. I see several moves necessitated by the signing.
1) LaRoche has to be traded no later than the deadline either for prospects to replenish those we lost in the Gio trade with a healthy Marrero taking his roster spot
2) Harper has to be ready to move up by June / July
3) Morse has to be traded for a Bourn type with the CF signing an extension prior to the trade ( can that be done ?)
4) I am not sure we want to make any trades within our division leaving the Bourn option off the table.
