According to Jeff Howe of the Boston Herald, the NFL has not notified Tom Brady or the Patriots of any punishment for deflate-gate. That doesn’t mean he won’t be punished, but the NFL has not told Brady anything yet.
So basically, this is on the NFL. Whatever disciplinary action occurs (if any) is entirely up to the league. Negotiations are non-existent.
If Brady will be punished, it has not been disclosed to him or the Patriots, according to a variety of sources.
This is just pure speculation on my part, but I think this is good news for Brady and the Pats.
