Bill Belichick is shopping a book, but don’t expect Tom Brady, Patriots tell-all

Bill Belichick is shopping a book, insiders tell Page Six.AP

Bill Belichick is adding a new page to his playbook.

The legendary NFL coach is shopping a book, multiple sources exclusively tell Page Six.

But the tome isn’t a behind-the-sidelines exposé on Tom Brady, Robert Kraft and the storied New England Patriots franchise.

Sources tell us the publication is more of the business variety.

Said an insider, “It’s the big business imprints that are the ones meeting and bidding on it.”

The infamously bellicose Belichick, 71, left the Patriots in January after 24 seasons — including six championship titles and nine Super Bowl appearances.

The enigmatic pigskin wizard reportedly wants to continue coaching, though his former rival, Peyton Manning, reportedly wants Belichick to join his Omaha Productions team if the grizzled veteran of the gridiron decides to go the broadcasting route.

We hear the book is being shopped via InkWell Management co-founder Richard Pine.

Pine did not get back to us, and Belichick’s rep did not comment.

Off the field, the former Patriots coach — who split from longtime girlfriend Linda Holliday last year, we previously reported — was recently spotted on an apparent date in Boston, a new report claims.

An anonymous tipster sent a photo to the Instagram gossip feed DeuxMoi, alleging they saw the storied football guru at dinner with a mystery woman this month.

“Ex-Pats Head Coach Bill Belichick with unnamed brunette at Contessa in Boston,” the submission read. “Clearly a date,” the witness claimed. “Check his smile and her shoes.”

The photo showed the duo sitting at a window table where they appeared to be in a deep conversation.

He was married to Debby Belichick from 1977 to 2006, and the former couple share three children.
