re: NFL Films chooses not to release audio of exchange between Tom Brady, Tyrann Mathieu

There's audio of TB retorting to a Saints defensive back. TB was calling on a Ref to throw a flag. The Saints player said something to TB along the lines of taunting him because the Refs didn't throw a flag. TB's retort "frick you, [Saints player name], you bitch!"

It's fair to surmise that this is the gist of what TB said to T. Mathieu.

I find it doubtful that TB would be using any kind of racial slur or even Gay slur, such as calling people a "fig". He just calls them a "bitch" or a "pussy" instead.
