Russell Wilson is a magician and he's having another magical season with the third-highest passer rating and a 7-to-0 touchdown-to-interception ratio. Wilson squares off against an equal opportunity Cardinals defense that can't stop the run nor the pass. Arizona ranks among the bottom-four in yards allowed and points per game surrendering nearly 30 a game.
The Seahawks are down defensively from previous years particularly in the secondary where the Legion of Boom no longer exists. 
Kyler Murray has transformed Arizona's offense. He's the perfect QB for the Cardinals because of his quickness and nimbleness, which masks his team's offensive line weaknesses. I expect Kliff Kingsbury to begin opening the playbook more for Murray especially being at home. David Johnson is an elite runner due for a bust out performance and Larry Fitzgerald is relevant again thanks to Murray and the Cardinals' much improved offense.
