Seattle Seahawks at Arizona Cardinals: 2021 Week 18 NFL Pick

Seattle Seahawks (6-10) at Arizona Cardinals (11-5)

The Cardinals pulled the upset in Dallas last week to keep their chances at winning the division alive, but there is still reason to be concerned about this team long-term. They started the season 7-0, but they benefited significantly from a +8 turnover margin, which was never likely to continue (+3 in 9 games since), and they have not been the same on either side of the ball since losing top wide receiver DeAndre Hopkins and stud interior defender JJ Watt for an extended period of time. They are also missing wide receiver Rondale Moore, who could be filling in for Hopkins, interior defender Jordan Phillips, who is supposed to be filling in for Watt, and a pair of starting cornerbacks Robert Alford and Marco Wilson.

In terms of schedule adjusted efficiency, which is based on more predictive metrics like yards per play and first down rate, the Cardinals rank 12th, 19th, and 18th on offense, defense, and special teams respectively and 10th in schedule adjusted mixed efficiency. That rank is not as good as their record and they are probably even worse than that suggests given the key players they are missing. My roster rankings, which take injuries into account, have the Cardinals just 1.5 points above average.

The Seahawks are just 6-10, but they have been hurt by a 2-5 record in one score games and have a +21 point differential, despite talented quarterback Russell Wilson missing three games and being limited for about three games upon his return. If you exclude that stretch, the Seahawks are 5-5 with a +32 point differential, with their defense (22nd in schedule adjusted efficiency) and their special teams (4th) serving as complementary units to an offense that has still performed above average when Wilson has been healthy this season.

I wish the Seahawks were not missing top linebacker Bobby Wagner, talented run stuffing interior defender Al Woods, and a pair of starting offensive lineman Gabe Jackson and Brandon Shell, but I was considering making the Seahawks my Pick of the Week before those players were ruled out, so even missing those players, I still only have the Seahawks a half point below average and, with the Cardinals 1.5 points above average, we’re getting line value with the Seahawks as underdogs of 6 points.

The Cardinals did win in Seattle earlier this year by 10 with backup quarterback Colt McCoy under center, but Russell Wilson was not 100% in that game, while McCoy played at a fairly high level for the three games he filled in for Murray. On top of that, just because a team won a divisional game on the road as underdogs does not mean they will beat that same opponent more easily in a same season, regular season game rematch. In fact, divisional favorites cover at just a 41.9% rate in that spot and only win straight up about half the time as favorites of 6.5 points or fewer. This isn’t a big play, but the Seahawks are bettable as 6-point underdogs.
