Ben Roethlisberger will be responsible for all changes at the line of scrimmage; before, the linemen and receivers made their own such calls. "Sometimes," Roethlisberger said, "change isn't necessarily bad." In the next month, Tomlin plans to rework much more than that. "We're going to have two-minute emphasis, red zone emphasis, short-yardage emphasis days, hurry-up offense, no-huddle offense," Tomlin said. "Just situations that need to be addressed. We know the outcome of games are defined by what happens on critical downs, in critical field position."
