Listen to just about any interview with just about any head coach and you’ll hear a lot of the same things: “We need to establish the run; we need to stop the run; we need to control the clock.” These mantras have become ingrained in head coaches at all levels of the sport, but it’s particularly noteworthy in the NFL where there’s nary a coach that hasn’t spent decades with the game embedded in their lives. This is how the NFL has become an echo chamber where new ideas are dismissed out of hand while the prevailing ideals say that toughness and physicality are what wins in this man’s sport.
