I think they need a management change. The front office has to go. It is still Theo Epstein.
Still the emphasis on offense. Not enough emphasis on speed, defense, pitching and smallball(=teamplay). Somewhere along the line, they stopped playing as a team, and more like individuals. Maybe the last few years. That's really a management problem. Not emphasizing the right things. Letting the opposition go wild stealing bases is a tipoff. Improper handling of pitching is another.
I don't think the present management is capable of changing anything, with their apparent fixed attitudes.
The best thing that can happen is Henry sells the team. That's a guarantee that management heads will role. I don't think the current management bunch has the judgement to turn the team around. They have proven that so far this year. They haven't been helped by Henry turning the money off, but almost everything they've done has turned into a pumpkin.
