It is an interesting read. (http://www.si.com/nfl/2014/10/15/bill-parcells-excerpt-bill-belichick-new-york-jets)
On the afternoon of Monday, Jan. 3, 2000, Bill Parcells announced his resignation from the Jets to the public, becoming the first head coach in franchise history to step down with a winning record: 30–20. He informed reporters that his defensive coordinator, Bill Belichick (whose contract from three years earlier ensured that he would take over whenever Parcells decided to leave), was empowered to make all football decisions, while Parcells himself would stay on as a confidant and consultant. And although the contract language lacked preciseness regarding ultimate authority, Parcells, still technically director of football operations at a $2.4 million salary, vowed not to overshadow Belichick. Big Bill insisted that thePatriots’ interest in hiring Little Bill -- they had sent a fax requesting permission to interview him -- was no factor in the development, although it certainly seemed to accelerate matters.
Parcells recalls, “He made a deal and then tried to get out of it. A deal’s a deal. You want out? You’re going to pay. Simple.”
