The Arizona Cardinals have already clinched their spot in the 2021 NFL postseason, but they have a chance to improve their seeding with a win over the Seattle Seahawks in the final week of the regular season.

Meanwhile, the Seahawks have nothing left to play for except pride and it may be the final time we'll see Pete Carrol and Russell Wilson teamed up together.

Seahawks vs. Cardinals Prediction and Pick

The difference maker in this game is going to be the secondary of the two teams. The Cardinals rank inside the top 10 in passing defense, while the Seahawks rank in the bottom 10. To be specific, Seattle is 25th in opponent yards per pass attempt, giving up 7 yards per throw. That's not a good sign when you're facing one of the most electric passers in the NFL in Kyler Murray.

The Seahawks, offensively, have look good at times this season, but their third down issues have plagued them all year. They're 27th in the league in third down conversion rating, getting a first down on just 35.36% of tries. That's a stark contrast to the Cardinals, who rank 5th in that stat, converting on 44.83% of third downs.

I'm going to try not to overthink this one, and back the playoff team in Arizona.

Pick: Cardinals -6.5
