I believe that Price believes that it's all the press' "fault" for reporting the news and in the process being critical of him. He doesn't like the press and the press doesn't like him, and the press is a big part of playing in Boston. When I see/listen to his post-game interviews I get the impression that he's saying what he's programmed to say and that he doesn't really mean it. He's simply saying, "Here's what I need to say. Now get out of my face."
He doesn't seem to like the intense spotlight in Boston, especially when it turns negative - which I don't blame him for. I mean, who would like that?? I'm beginning to think that he's now coming to grips with the fact that he thrives best in low-pressure situations where he can exceed expectations and Boston may not be the best place for him.
As to the Eck thing, I know there are exceptions to this (Yankees, A's of the past) but usually discord in the clubhouse will lead to poor performance on the field. As fans we expect solid performance on the field, something there hasn't been much of lately, we're looking for reasons/excuses for it. The dust-up on the plane takes care of that for us.
