Whoever claimed that Brady was "growling" in this presser is completely 100%, out of their freaking minds...
I just watched the 6:00 video, and he does everything that Tom Brady usually does. He answers his questions carefully, praises the strengths of the opposition, and points to the challenge in front of the team.
In his answers about the OL, he is careful not to give them anything that can be considered controversial, by stating that they ALL have issues that need to be corrected.
As far as him joking around---he is literally laughing and smiling during the question posed about his facebook page, as well as the question posed about Chandler Jones playing as a receiver.
If anything, it will be stupid comments by the local media like this that do piss him off. They should be ashamed of themselves after this kind of ridiculous leaping to conclusions.
