I cannot believe that the show does not consult a person who knows negotiation. The Dance that Rogers and the Packers are doing is well recognizable by someone who can see such rhythms. Every expert I have seen on there postulates but is missing such key particulars that the ending message sells, but it doesn't get close to a cogent analysis.
It keeps the ball rolling, but with no awareness of which Y in the path will be taken by that ball.
