Jerry Jones and Arthur Blank had plenty of opportunities to exchange pleasantries before the Dallas Cowboys and Atlanta Falcons game. Each strolled the field during pregame warm-ups, but didn’t bother saying hello or shaking hands with each other. According to a Cowboys staffer, it’s customary for the home owner to walk across the field and greet the visiting owner. Jones made himself visible and available throughout pre-game warmups, walking the sideline in front of the Cowboys bench area. But Blank, who spent much of the time before the game in the middle of the field, didn’t make an attempt to move toward Jones on the Cowboys sideline.
