Not coincidentally, the Bucs were also New England's opponent in the regular-season opener. A few days before the game, Walsh told Senate investigators, according to notes of the interview, a backup quarterback named John Friesz was summoned to Belichick's office. Offensive coordinator Charlie Weis and a professorial, quirky man named Ernie Adams were present. Adams was -- and still is -- a mystery in the Patriots building, a socially awkward amateur historian of pro football and the Vietnam War who often wore the same red, hole-ridden Patriots sweater from the 1970s. He had a photographic memory, and Brady once said that Adams "knows more about professional football than anyone I ever met."
