The Seahawks, who were swept by the 49ers in 2006, routed the 49ers on Sunday, 23-3, and took control of the NFC West. Running back Shaun Alexander, playing with a cast on his cracked left wrist, finished with 78 yards, while QB Matt Hasselbeck passed for 281 yards and two touchdowns. ... Pittsburgh lost at Arizona, 21-14. Ben Roethlisberger mounted a fourth-quarter comeback that ended when his pass with 9 seconds left was intercepted by Cardinals cornerback Ralph Brown
Seahawks LB Julian Peterson vs. Roethlisberger. The Steelers are coming off their first loss of the year in which they surrendered four sacks to Arizona -- their total through the first three weeks. The Seahawks, meanwhile, are coming off a six-sack effort against San Francisco, with three coming from Peterson. If Pittsburgh's O-line can keep Roethlisberger upright, he should have enough time to exploit a mediocre secondary.
