It really also depends on who you think of as a core player for this team. The obvious "is he or isn't he" is Bradley. I think - and i might be wrong, especially in the wake of incomplete information - that the Sox can reset this off-season and still keep Betts, but that absolutely necessitates non-tendering/trading Bradley and replacing him with a cheaper alternative. And I think of the staff is healthy, the Sox can still be competitive if they do that.
Of course, there is no way right now to even guess what the plan is, as we don't have a GM with some sort of history that allows for educated guesses. So it's just about looking at payroll numbers...
