Exactly. It does not matter what your defense is, if they are on the field most of the game, they are going to give up points. POints against is very subjective on more than just the defense. If you turn the ball over and the other team scores from the 5 yard line in 3 tries, whos fault is it. People tend to use what makes their argument work as to what really consititues being good or bad. The pats offense for 19 years was the most consistent offense in football, they are not going to give up a ton of points off mistakes.
