I don't see Cole, Strasburg or Rendon happening either. But there is a solid group of FA after those three before you get the dumpster diving you're pushing for. Plus, Ozuna and JDM are not getting 9 figure deals.
The Sox need to sign one of Grandal or JD Martinez. A big bat has to happen. They need to sign a SP just below the tier of Cole/Strasburg - whether that is Wheeler, or Bumgarner, or Ryu, they all work. After that, I am OK filling in the gaps with guys like Hamels, Miley, Alex Gordon/Kole Calhoun/Dickerson/Gardner, etc., but they need to add two of the ten or so FA, or this is never going to work.
