I am not an Xs and Os guy. The NFL offense has changed. Why can't we go back to smashmouth football? Insert a full-time fullback like we had with Tim Lester. A tight-end that can block and catch. Fill the offensive line with high draft picks. Get two stud Wrs...Physically move guys off the ball, then hit them up top with Play-action? Why do we not see this anymore? What negative is there to running this kind of offense in 2021?
