Your complaint about Breslow makes no sense. The most important communicator on every MLB team is the manager, who talks to the media, answers questions, etc after every single game. CBO's pronouncements do not need to be all that informative. In fact, the less said, the better. Do you remember what was said after JH and Breslow flew to KC to talk to Devers? "We communicated."
As for communicating with other teams about trades, etc,, are you unaware that Breslow transformed the Sox by bringing in Crochet, Bregman, Chapman, and Narvaez? Also Giolito, who needed a year to recover from an injury. Buehler bombed, agreed. Letting Sale go was a mistake. I'm sure there were others, but this is Breslow's first CBO job and he came in knowing that JH was unlikely to return to his biggest payroll in MLB days. This year the payroll is 12th.
Do you remember what we all clamored for in July? Pitching, pitching, pitching. We didn't get a #2 starter, but right now the Sox have their best rotation--Crochet, Bello, Giolito, May, and Tolle--in a long time. And the bullpen is pretty good too. And, thanks to the partnership between Cora and Breslow, the defense is also the best in years.
I will say that Breslow absolutely must be able to communicate with his manager and with those above him. The evidence is overwhelming that he does both well.
