Zee's game preview covered this matchup pretty well, so I'll keep this short. The Cardinals may have a halfway decent offense again, but their defense is still as questionable as ever. If Tarvaris Jackson is going to prove to the fans and the team that he deserves to keep the starting QB job, today is as good a day as any.
And in case you missed it, Pro Football Weekly's Dan Arkush recently wrote that Earl Thomas and Kam Chancellor "could become the NFL's most electrifying safety tandem." I'd say that sounds about right -- whenever I start feeling too pessimistic about the Seahawks this season, I just close my eyes and remember watching Thomas bodily throw TE Vernon Davis out of bounds back in week 1. That puts a smile on my face every time.
