I'd be fine with them not signing anyone major this offseason, too. I'd like to see Morse start next season in LF with LaRoche at 1B so they can build LaRoche's trade value a bit. Morse is bad defensively in the OF but they'll get by and it would only be temporary.
If CC is a free agent and interested in leaving the Yanks, I'd throw big money at him. Otherwise, it doesn't look like a very promising class this year. Edwin Jackson and CJ Wilson could be decent signings but I think they'll likely be significantly overpaid.
After next season, Upton, Bourn, and Greinke are all free agents. I wouldn't mind a trade for Upton or Bourn this offseason as long as we get them at a discount due to their impending free agency.
