Fangio had great game plan for Dallas who was rolling red-hot. He was great against the Cowboys and really dialed in a defensive scheme to shut down Dak, Zeke and the receivers. Fangio could break down film of the upcoming opponents and assist the defensive coaches in film prep. He doesn't even need to work with the players. He can be a hired gun to help scheme opponents and cut film. Vance Joseph and Dan Quinn were cast-offs that proved they have expertise. What if Quinn leaves? From wiki, "Fangio’s defenses have consistently been among the most productive in the NFL in a number of categories, including scoring defense, total yards allowed and fewest penalties. His defenses have ranked in the league’s top-five in yards allowed in eight of the last 13 years while placing in the NFL’s top-5 in fewest points allowed seven times over that span". A 5 week contract. Go Dallas!!!
