I totally agree. They are really scary, in every aspect of the game. What they are doing would be impressive against Minnesota or Jacksonville, but NO has one of the most dynamic offenses in the NFL, and has been very good defensively this year, too.
I could point out that Seattle looked just as dominant last year against the 49ers, blowing them out 42-13, I think it was, at home in the second to last game of the season. Then struggled to beat Washington (the game turned around for them when RGIII went down to injury), and lost to Atlanta in the playoffs. But those games were on the road. Seattle is not going to play on the road this year, at least not until the SB. They could have trouble in NYC if the weather is really cold. OTOH, bad weather usually affects passing more than running, and Seattle has an excellent ground game, whereas the teams it would most likely face in the SB, Denver or NE, depend much more on passing.
Edit: One thing that bothers me about Seattle's dominance at home is that it seems to depend in large part on the incredible noise level at their stadium--a level that set a record, that is well above the threshold of pain. As others are pointing out, this seems like an unfair advantage, not to mention a health hazard. The Saints, and other teams that have played there, said afterwards they could not hear their signals, which obviously means they can't change plays at the line of scrimmage. Their first play from scrimmage was a big loss because, allegedly, they did try to change it, and the linemen did not pick it up.
If the NFL can't or won't crack down on this, here's an obvious suggestion: why don't visiting teams wear earphones that block out the sound? The QB could call signals through a microphone that all his teammates could hear. Since the noise level is so high that nobody can hear anything even screamed into the air, what could they possibly have to lose?
Foxxy, you gotta love Jeff Fisher. Fourth and long deep in his own territory against the 49ers, trailing by just 10 with lots of time left. And he tries a fake punt. It failed, and the Niners immediately scored.
Then the Rams drive down the field and have 4th and 11 in the RZ. Again he goes for it, and again he fails. Not sure I agree with that call. At that point they needed 2 TDs and a FG, might as well take the FG when the TD at that point was so unlikely.
