I don't think he's a jerk and I don't think he blanketly dislikes all of the media.
I think he is determined not to disclose ANY injury information, hates stupid questions, and hates it more when stupid questions are repeated.
His focus is on game strategy, and as long as he isn't giving away valuable info, he will answer most questions about strategy in detail. Hence the long answers to questions about timeouts, the use of cameras to correct bad calls, the evolution of the kicking game, situational football, etc.
The problem is that reporters will continually probe him for injury information, knowing that that they 100% won't get squat out of him, and so I believe that the purpose of them asking the question in the first place is either that they are stupid or that they are trying to make him look bad.
He can be moody after a loss sometimes and not say much of anything, other than personally taking blame for the loss ("I need to coach better"), but that's human nature not jerkyness.
are we gonna have people combing through other fans forums and getting mad over anything bad someone says about the patriots?
serious question...are you new to the NFL message boards thing? Getting mad over anything anybody says is de riguer on the internet...in fact, getting mad over anything anybody says GOOD is also taken for granted.
