i dont think they are afraid of him, i just think they have figured out that he wont discuss certain things or address those types of questions, he's very good at blowing off things he doesnt want to talk about. so maybe they just try to ask questions that will give them something to write about, otherwise they come away with nothing. And they still have to peice something together.
Parcells has conditioned them, and now he has control. I dont think they are afraid of upsetting him because they are afraid of him, i think they are afraid of him making their job even harder because they know he can sit through an interview and answer questions in such a way that leaves them high and dry with nothing good to write about. And so its a little game they all play, one that ultimately works more in parcells favor, but essentially, he is holding all the cards cause jerry has given him that much control and basically backs him up with whatever he says.
