I think the problem is Henry, Werner and Lucchino left the Red Sox to be entirely run by Epstein & Co the last few years. That's the power given after he took off his gorilla suit. Lucchino turned his attention to the ballpark improvements and Henry/Werner to new soccer team investments in Europe. I don't think they paid much attention to player personnel. Sure, they probably signed off on the major free agents, but it looks like it was really a rubber stamp on whatever Epstein wanted. With the collapse this year, they probably took a hard look at the baseball operations, to figure out what was wrong. It didn't take them long to conclude they needed a change in the manager and the GM. Tito and Theo were both given the opportunity to exit gracefully.
The problem is, they really hadn't thought out what type of manager they wanted, and left
that to the "new" GM, BC, who was a known commodity--the easy way out. At some point, they realized they didn't want the status quo for a manager, and changed the direction of the manager search. Too bad all this was done in public, which raised control issues.
I hope at this point the ownership has made clear what LL's and BC's responsibilities are, and what is expected from the new manager. It's long overdue.
