There's one thing about the interview that I can't get out of my mind.
Brady, is man of very few words who always wants to be in control of his message. He twice used the phrase "margin of error." Towards the beginning and then at the end of the interview. There's no secret that he views windows for his receivers in millimetres, not just inches. As he's gotten older, he's increasingly depended on precision for his success. He doesn't feel he has much margin for error.
I never try to read anything into Brady's affect during an interview since it's pretty much the same all the time. He's always under control, practically flat, as he was with King. But his repeating that phrase makes me think that he feels something important is missing and he's not sure he can get it fixed anytime soon.
