Heading into Sunday's game against a Chargers defense ranked third in the league against the pass, the Vikings made what wide receiver Justin Jefferson called a "big adjustment," emphasizing a desire to get the ball to him and Adam Thielen with a more aggressive approach.
On Sunday, at least, that approach still didn't take the form of many deep strikes. During the Vikings' 27-20 win, Kirk Cousins' biggest completions of the day — a pair of 27-yard sideline connections with Jefferson — were two of the only three passes he attempted of 20 yards or more. But he exploited an area of the passing game he hasn't used much this season: the middle of the field.
According to Pro Football Focus, Cousins attempted seven passes between 10 and 19 yards downfield on Sunday, connecting on four of them for 78 yards and helping the Vikings solve a defensive scheme they're going to see again in some of their most important games the rest of the way. He had one pass nearly intercepted by Tevaughn Campbell after Thielen fell down, but made some of his biggest throws by exploiting seams in the Chargers' zone coverages, fitting throws in behind their linebackers and in front of their safeties.
He hit Jefferson for a 12-yard third-down pickup that had Chris Harris furious with teammates because of a coverage breakdown, and beat a blitz with a 16-yard throw to Thielen later on the same drive. His final completion of the day — an 18-yard shot over the middle to Thielen on third-and-20 — put the Vikings in position to go for it on fourth down and seal the game with a toss play to Dalvin Cook.
"I think the one to Adam on third down was pressure, so I was hot and used my hot throw and they voided the middle of the field [on the blitz]," Cousins said. "On the deeper one to Adam on the last third down of the game, it was just a two-deep shell and that was where the void was. They did play a fair amount of split safety and I guess that was just kind of where my reads took me."
The Chargers hired coach Brandon Staley after his work as the Rams' defensive coordinator, where his iteration of Vic Fangio's defense used lighter boxes with split-safety looks to take away big plays downfield. The thesis of Staley's defense, which has become popular around the league, is a willingness to give up yardage on the ground while forcing offenses to work methodically and squeeze throws into traffic.
That Cousins was able to beat the scheme Sunday is significant first of all because it helped the Vikings win a game they badly needed. But if it carries forward through the season — starting with a Packers defense that's adopted a similar scheme to Staley's under defensive coordinator Joe Barry — it could help the Vikings remain productive against teams intent on slowing Thielen and Jefferson down.
Cousins has the second-highest passer rating in the league on intermediate throws this season, per PFF, but he has attempted the third-lowest percentage of those throws in the NFL this season (only Jared Goff and Joe Burrow have done it less). As the Vikings have reduced the frequency with which they use play action, and as they've taken fewer deep shots, their passing game had often been reduced to short throws or checkdowns, particularly after the first drive of the game.
