This is starting to become conventional wisdom, but I don't think it's that iron-clad. There's this perception out there that when you are rebuilding, you shouldn't sign any FA. If there's a good player available and you like him and his price is fair, get him. It's part of building your team. There are factors to consider (losing a draft pick to sign a player with a QO, signing someone over 35, overlapping someone on the major league roster), but there's also a risk of being too cute and passing on a fair deal for a good player to be left with worse options the following year. Harper and Machado are pipedreams, and that's fine. But guys like Pollock, Corbin, Richards, Donaldson and Keuchel could all make varying degrees of sense for the Sox in the right situation. Unless the Sox are so zeroed in on a guy like Arenado, Rendon or Goldschmidt in the following year's class, I hop the Sox walk away with something this winter. (That said, if the price tag on any of those guys exceeds what value you think they'd bring, then it's an easy pass.)
