Not good. For the 4th time in 6 weeks, Seahawks will be facing a team using their 2nd or 3rd string QB. The other 2 weeks they faced a mediocre Kaepernick. They're a great defense, but they've faced mediocre offenses lately. St. Louis is a very inconsistent team, but they do sometimes play good enough defense to play with anybody. They did beat Seattle earlier this year.
