Honestly what's most important to me is that Brady and his team give no respect to the Commissioner, in their tone, body language, and engagement in the proceeding. Don't let him get away with acting like he is completely in control of this; insist that it is a meeting of equals. If he starts to insist, in any way, that everyone from Brady's side must be subservient to his agenda, or even polite, push back and be as cold and hard ass as possible.
I want Brady and his team to send the message that they have no respect for Goodell through this meeting. The Goodell and the NFL has an agenda against the Patriots and that this is part of the conversation. No "press conference nice guy Tom." I want Tom to act as if Goodell and his team are an NFL defense that stands between him and another ring.
And, I want Brady and his team to insist that the draft picks and fine are a penalty against him personally, and are part of what is under discussion, because they handicap him and his team from playing on an equal playing field...in other words, compromise the integrity of the game.
I know this is entirely emotional and non strategic. But that's how I feel.
