Up until it self-destructed in about the time it takes per day to perfect one's abdominal muscles, Seattle's defense was simply the best. Better than all the rest. Better than anyone .
OK, enough. Seriously, this time last week Seattle's D was ranked first in total defense and scoring defense, having allowed a meager 13 points in three games, including the first shutout of the 49ers in a league-record 420 contests.
