They went into the same mode as they did when they went up 3 to1 games vs the Cubs in the Series.
Ohhhh, we got this and they, the Cubs, know it's over. Let's just get through the rest of the game. Oh we lost that one? It's ok. We'll crush 'em the next game. But next game never comes. This is why there are critics of Terry Francona. He's a player's manager and doesn't develop a good killer instinct in his players by being too relaxed. Not my opinion, but I can see how others may think this way.
I'm not sure I'm buying it, but there is a similar sentiment about his style. He latches on to players too long and it can be a detriment in the long run.
That said I'm not for letting him go. I don't know of a better replacement other than Sandy Alomar and he's an unknown. When the Dolan's screw this team up enough to let Tito go the job is likely Alomar's.
