A depth chart is about what's on the paper. The NFL is about what's on the turf. A standout example of that was delivered on Saturday in Buffalo, where the New York Giants opened their preseason with the debut of their prized QB pupil

The Bills are a much better team than the Giants, and while much of that is the star quarterback and difference makers on both sides of the ball, there’s another reason that becomes apparent quickly during preseason football. Good teams usually have better depth throughout their roster, giving them an advantage when it becomes backups vs. backups.
