Ok, but if salary is the problem (and I don't think there's much doubt that it is) then big salaries have to be eliminated along with players who may not be making *big* money but are overpaid in the eyes of the FO. The low-hanging fruit there are Betts, JDM, Porcillo, Price, and Sale. The second tier would be Moreland, JBJ (although I don't agree), and Bogaerts would both bring a good return and eliminate salary. Of those eight I expect to see four or five of them gone by next season.
The only regulars whom I think are safe are Devers, Benintendi, and Vazquez...and possibly Bogaerts if they're willing to hold onto that salary.
Reality Check: This team has a lot of money tied up in a few players and if JD wants to reset below the LT line many of them are going to have to go. This isn't going to be pretty for the fans because the Sox don't have the farm to replace them. That means that they're going to have to go outside the organization and sign lesser talent FA's which will impact the talent on the team. That's how a team with a weak farm system resets.
Personally (and hopefully) I'm still believing that whomever fills DD's shoes sees that the position players are still capable of competing with anyone and they don't start cleaning house - but I also believe that may be nothing more than blind optimism.
