You're an idiot. Breslow sabotaged this team--not intentionally, of course--by dumping Sale to the Braves while still paying him $17M and picking up Giolito for $19M x 2 years, one of which is already down the drain. He also failed to bring in any real bullpen help.
The heart of the Sox lineup, which has made a winning season possible, was here when Breslow arrived: Duran, Abreu, Casas, Abreu, Devers, Wong, Rafaela, Hamilton, Yoshida. And for awhile the rotation of Houck, Crawford, Pivetta, Whitlock, and Bello--all of whom were here before Breslow--was also doing pretty good.
To Breslow's credit, he insisted on a new pitching coach, and Bailey has been pretty good. Also in his defense is that the owner has been reluctant to support significant investments in pitching, largely because he was snake bit by the huge David Price and Chris Sale contracts.
Cora is a big reason why the Sox have a winning record this year. He managed the best Sox team, 2018, in Sox history. And 3 years later with Betts, Benintendi, JBJ, Price, Kimbel, et al, gone--and Sale on the IL--Cora managed that team to the ALCS. In comparison, the 2016 and 2017 Sox teams, with a lot more talent, won the AL East both seasons but were killed in the ALDS, 3 games to none, both times. That was with Farrell as manager.
