When it comes right down to it, there is only 1 measurable defensive stat that means anything --- Points allowed.
The Ravens allowed 16.7 points per game. If you look at a team like Miami, who allowed 19.6 points per game and had the misfortune of having two of those games against the Patriots (who hung a total of 65 points on them).
Statistically, take out the games that included us (we unfairly influenced their defensive ranking ), and the Non Patriot-playing Dolphins defense is basically on par with Baltimore defense in points allowed (16.7 vs. 17.6).
If you remember, we had no issue hanging an average of 32 points on them.
In fact, if you look at 10 top defenses in
points allowed, we played 3 of them (Pittsburgh, Miami and Philly)........ If you take out the NE games, all 3 of those teams improve statistically (2 significantly). Pitt (ranked #1) stays #1, but their PPG improves a few tenths of a point. Miami and Philly improve dramatically to 4th and 6th respectively (from 7th and 10th).
Conversely, Baltimore....... when faced with teams whose offenses are in the
top 10 in points for, they only played two (SF and SD). They handled SF okay, but got schooled by SD. They average 20 PPG allowed between the to, which is significantly worse then their average of 16.6.
Bottom line...... Sure, Baltimore has a good defense, but they really haven't played very many good offenses, and when they did, they allowed more points then they normally do. When the Pats played top-10 defenses, we still average over 30 ppg. That's slightly under the 32 we average against all teams, but certainly enough to win MOST of the time.
