After a low-scoring victory in Detroit, the Seahawks played their Week 2 home-opener against their fellow NFC West rival, the Arizona Cardinals.  Unlike Game 1, Seattle's offense got off to a strong start, as RB Shaun Alexander got a 2-yard TD run, while QB Matt Hasselbeck completed a 49-yard TD pass to WR Darrell Jackson.  That's how the rest of the first half would end up.  In the third quarter, the score of the period was Arizona kicker Neil Rackers completed a 43-yard field goal.  In the fourth quarter, the Seahawks got a 1-yard TD run by FB Mack Strong.  The Cardinals would get a touchdown, which would come in the form of a 40-yard TD pass from QB Kurt Warner to WR Bryant Johnson, but fortunately, Seattle would maintain the lead for the win.  The Seahawks would extend their home winning streak to 11 straight games and improved to 2-0.
