Points are a volume stats, and like any other volume stats they are misleading.
Obviously, a team needs to score more points than the opponents to win a game but that is a ''fact'' that is only applicable on a game by game basis, not good as a measure of comparison over an entire season. Yesterday game is an example that shows that looking only at the number of point given is misleading : the Steelers scored only 23 points on offense, but they only punted once, and that happened 59 minutes into the game. They took control of the game with a short passing attack, they didn't need to go for the quick score...they took 40 minutes of ball control, not giving the Pats offense any chance to get on track. The Steelers converted 10 of 16 3rd downs, a couple of 7+ yards (and one of 15 yards). This is abysmal.
The Steelers game plan yesterday wasn't to go for a shootout against the Pats, but to limit the number of time the Pats offense would get the ball. They decided to use the pass, and their game plan is obvious just by looking at Roethlisberger yard per pass attempt (YPA) stat :7.3. This is well below his season avg of 8.1. Since the Pats have the 2nd worse defensive YPA right now, behind only the Colts, it then become obvious that it was done on purpose, not because the Pats pass defense somewhat ''limited'' Roethlisberger, but because it was the Steelers game plan to control the ball with short passes. I couldn't care less that the Steelers only scored 25 points, which looks better on the score sheet than the 62 points the Colts give away a couple of weeks ago, because I never felt the Pats had a real chance to win after the 1st quarter either.
The Pats are near the bottom of the league in every efficiency defensive statistics : 3rd down conversion, yards per play (32th), yards per pass play (31st), defensive passer rating (27th), sack per pass attempt (25th).
That might be good enough to beat teams that are mistake-prone, but not a more efficient team like the Steelers were yesterday, or the Packers are at this time.
I believe the problem is roster-related at this time, but I'm also beginning to be questioning the bend-but-don't-break philosophy. The passing game is more efficient than ever, which means less mistake are done (the league avg passer rating was 80.1 in 2004, our last Super Bowl, it is now at 84.5) so before the opponent commits the drive-killing mistake, it takes a few more play each drive...thus better field position and more scoring opportunities.
