Sox Baiting

Some fodder for Red Sox Nation (I'm looking at you, A.W.):

When you give up 7+ runs a game, that's on your pitching staff. But when you give up 7 runs in an inning, twice, isn't that on the manager? You can't blame a manager if his team gives up, say, 4 runs at a time. But isn't his job to keep a firm enough grasp on the game, the opposing lineup, and his bullpen, to be able to hold keep the bleeding from becoming a hemorrhage? Particularly in the playoffs?
