Should be a great game when the 11-3 49ers meet the 11-3 Seahawks to decide the NFC West Division. Oh wait, that's next week. 
Seattle can't help but be looking ahead to that crucial matchup. Problem is the Seahawks aren't good enough to cover this high of a number especially in a look-ahead spot. 
The Seahawks being eight games above .500 doesn't match their statistics and point differential. They have outscored their opponents by just 26 points on the season. Seattle only has 24 sacks, which ranks among the bottom-three. The Seahawks also have half a dozen injuries to key defenders, including underrated free safety Quandre Diggs. He carries a doubtful tag while Seattle's other banged-up defensive players are questionable. 
The Cardinals are adept offensively. They have scored 25 or more points in seven of their last 10 games. Kyler Murray is a poor man's Russell Wilson. His weapons match the Seahawks especially with Josh Gordon back on suspension and likely done in the NFL, which was a distraction for Seattle this week. 
The Seahawks have actually played better on the road. They have covered only twice during their last seven home games often overpriced like they are here. Arizona is 8-4-1 ATS as an underdog this season.
