The Vikings' cornerback plan: With Holton Hill out because of a foot injury on Sunday night, the Vikings kept their two rookies (Cameron Dantzler and Jeff Gladney) on the field for every snap, playing Mike Hughes on 43 of their 54 defensive snaps when the Vikings were in a nickel defense. Hughes played both in the slot and at one of the outside corner spots on Sunday night, with Gladney moving inside in some situations. The Vikings have toyed with different combinations at corner this season, and a return from Hill would undoubtedly change the mix again. But it's worth pointing out that on Sunday night, the Vikings were comfortable enough with their two rookies to keep them on the field for every snap of the game.
Two players who stood out
Irv Smith: The second-year tight end's lack of production had been a concern through the first quarter of the season, but Smith played a major role from the Vikings' first snap of the game on Sunday night. Cousins tried him on a slant route on the game's first play from scrimmage, before K.J. Wright batted the throw down, and hit him for 23 yards on the next play when Smith made a diving catch. Smith ended the night with four catches for 64 yards, playing in the slot, splitting out wide and setting up on the line of scrimmage in 12 and 13 personnel. Smith (59 snaps) played almost as much as Kyle Rudolph (64), while Tyler Conklin saw 10 snaps and Rashod Hill got two as an extra tight end.
Eric Wilson: The linebacker has gone from a base-defense player to an every-down player in Anthony Barr's absence, and Sunday night was probably his best game as a pro. He fell down in the end zone while in coverage on Will Dissly's touchdown, but had a sack and two other hits on Russell Wilson (including one that forced a throwaway on Seattle's final drive) and made a terrific play to pick off Wilson along the Vikings' sideline for a fourth-quarter interception that appeared it would give Minnesota a chance to ice the game.
Two areas of concern
The second-half secondary: The Vikings kept their safeties back in the first half to take away Russell Wilson's deep shots, and their plan worked brilliantly as they built a 13-0 lead. But rookie mistakes on the Seahawks' final drive appeared to do the Vikings in. On Wilson's 39-yard completion to D.K. Metcalf on fourth-and-10, Dantzler appeared to misplay a ball Zimmer said he thought the Vikings were going to intercept, giving Metcalf space at the last second to make an easy catch. And on Wilson's fourth-down game-winner to Metcalf, the Seahawks ran a mesh concept with twin crossing routes designed to create a natural pick in the middle of the field. They occupied Harrison Smith with an out route from tight end Greg Olsen, while Gladney handled Tyler Lockett in coverage. But after initially reacting to Metcalf's route, Dantzler stayed on his side of the field, rather than carrying Metcalf's route while Hughes followed Freddie Swain's crossing route. After the play, NBC's cameras showed Harrison Smith giving Dantzler a sharp rebuke that wasn't hard for lip-readers to decipher.
Interior offensive line play: This has been another consistent theme throughout the year, but it bears repeating after a dreadful night for Dru Samia, who was flagged for holding three times (and had a block-in-the-back penalty the Seahawks declined). Dakota Dozier was pushed back into Cousins' lap in the first quarter, and got beat by Damontre Moore on Cousins' first fumble of the game. The Vikings ran the ball for more than 200 yards on Sunday night, and the line deserves credit for that, but pass protection remains a concern.
One big question
Are the Vikings now playing for the future? Of the 146 teams who have started 1-4 since 1990, just 10 reached the playoffs in a 12-team format (with another three — including the 2005 Vikings — missing the playoffs at 9-7). The Vikings will play a winless Falcons team at home on Sunday before their bye week, and it's difficult to concede anything in a year where 14 teams will make the playoffs and any number of strange outcomes could be possible given the circumstances of the season. But the smart money is on the Vikings being sensible with Dalvin Cook's groin injury a week before their bye, and Sunday night brought striking reminders about how much a transcendent quarterback can do to overcome weaknesses elsewhere on the roster. The Vikings have a young secondary, and a quarterback who's good most of the time. That might not be the kind of combination that can produce the 11-week run of consistent success they'd need to reach the playoffs in 2020.
