I don’t need the proof beyond what you said.
Of course, Grady was also in a different status than Cora. Cora agrees with, assuming he flat out isn’t responsible for, the Sox analytical approach. I doubt the Sox have told him to use Cooper Criswell only in long relief mop up roles and instead just force the issue with Houck and Crawford. It’s possible (re:likely) Cora didn’t see Criswell as the solution I am proposing, and maybe he’s right. But that’s a different matter.
I can tell you this and I would be shocked if you disagreed - if Cora can recover from his cheating scandal and regain his position in Boston, be offered promotions, and receive the largest managerial extension in team history, he is absolutely not getting fired because he disagreed with Breslow or Bailey on how to use a 27yo minimum wage veteran pitcher in Cooper Criswell. I think it’s a safe bet Cora has some free rein there…
