Justin Fields carried the ball 14 times during his Pittsburgh Steelers debut. As it turns out, that is more than any other Steelers quarterback has ever run it during a game. At least, that depends on your definition of a quarterback, a position that evolved enormously over time.
So let’s say, in the modern era, Justin Fields set a Steelers franchise record for carries by a starting quarterback. Back in the 1930s, ‘40s, and ‘50s, you had backs like Whizzer White, “Bullet” Bill Dudley, Johnny Clement, and Joe Geri, who would put the ball in the air.
