It was also that fax, in which the Pats were asking for permission to talk to BB, that led to BB resigning as HC of the NYJ. When the fax came in, fat ass Parcells received it, and immediately lumbered down the hall and resigned as head coach. By doing that, it triggered BB's contract, and he became head coach of the Jets, which meant, he couldn't speak to any other teams. BB was furious about it, and pissed that they had backdoored him into the HC position, without giving him the opportunity to talk to the Pats, and he resigned the next day. Then Parcells contacted Kraft and negotiated the release of BB from the contract, so he could take the job with the Pats.
That fax literally changed the history of NFL football.
