Really though do they care that much? How much of a motivator is that? The business of the Red Sox would take some hit but its so large and successful they can make moves like they did with Betts and Xander not really skipping a beat. Whats the real cost of moving on from even Devers too, to the business? Honest question - I don't know that answer. Just musing about the calculation.
FO and ownership know that there its all about winning and if they win the fans support them. The do well financially even when they arent great. If they don't win much, it doesn't matter if they have Devers or not, the fanbase is up in arms. He might became a focal point of the criticism if gone, but if they suck the fanbase will find other criticism topics, even if they pay him or don't.
