If Greinke were to re-sign, they'd still have some money to play with that they wouldn't be paying Marcum/Wolf/K-Rod. Now, some of that would go to Greinke and raises to Weeks, Hart, and other arbitration cases, but they could fill shortstop and first base. I think CF is fine with some of the guys they have in their system. Of course, I am not expecting Greinke to re-sign, so this is probably all moot.
