Assuming, as past free agent markets have dictated, that we are unable to land one of the 'big guys' mentioned above.....and assuming Pierre is re-signed and J.J. stays in Right (of which I hope they can trade him for something soon!)....our needs would be a 1. power hitting outfielder 2. run-producing second baseman 3. possible conisderation of upgrade at SS and 4. probably TWO starting pitchers (assuming Z, Prior, and Marshall or Marmol can stick).
That said, thinking reasonable, there are still some potential FA's out there who would seem to fit in here well if given the chance. For instance:
2B: Luis Castillo would be a Great fit, and unlikely to break the bank
OF: Jermaine Dye (unless the Sox pick up his option), Jose Guillen (if he can stay healthy), Garciapara (?any convincing to try the outfield again?), Trot Nixon (if given the opportunity to play everyday, might show a little more pop), or even Moises Alou for a one year shot
SS: Lugo, Counsell (may have some left in the tank)
SP: Gil Meche, Mike Mussina (doubtful to see his Yankee option picked up at that price), Mark Redman, Cory Lidle
Sure it'd be great to get one of the big guys, but the alternatives may not be too far off(with the exception of the OF opening with Carlos Lee) and certainly cheaper.
