Getty Bills quarterback Josh Allen and his wife, Hailee Steinfeld. The Buffalo Bills kicked off their preseason opener against the New York Giants on August 9. While Bills quarterback Josh Allen took what turned out to be his only preseason snaps during the opener last year, head coach Sean McDermott announced he’d sit out on Saturday. Buffalo took a 34-25 loss in the meaningless exhibition game. Allen’s backup, Mitch Trubisky, took over as the team’s starter and played the entire first half.
