We'll spend about 40 million on a group of acquisitions that resemble this: Jason Castro, Andrew Cashner, Jorge de la Rosa, Kelly Johnson, Jeff Francoeur.
That will put us in the 80-85 range on the expected win curve.
I agree with your general premise, but I don't think all the additions will come as FAs.
I think Castro and De La Rosa are very likely targets, and they would cost a combined ~$25M per year.
I also think KJ and Frenchy (or similar) are likely additions to the bench for a total cost of $2M-$3M per year.
Ideally, I would like to see one of Inciarte or Mallex (plus an arm) traded to bring in a controllable SP or 3B.
If one of Mallex or Inciarte are traded, I would like to see Rajai Davis signed to be the 4th OFer.
