Steve coached football, basketball and track at Hiram, and Jeannette went above and beyond to aid in his coaching duties away from the field.

"She had as much football knowledge as little Bill did at one point," family friend and 1960 Heisman Trophy winner Joe Bellino said in Ian O'Connor's book Belichick: The Making of the Greatest Football Coach of All Time. "I think she might've coordinated all of Steve's notes. She probably viewed the game films as much as Steve did."

Steve echoed the sentiment, questioning to O'Connor whether "there's a woman in the country who knows more about football."

NESN's Doug Kyed reported the Patriots postponed Belichick's regular press conference until Thursday.
