Two other players who stood out:
Everson Griffen: All offseason, the Vikings have expressed guarded optimism that Griffen could return to being the player he was from 2014-17, after a mental health episode sent things off course last year. The 31-year-old defensive end showed early signs of a return to form, posting a sack on Sunday and providing a more consistent force against the run than he did last year. That second point is especially important, given how good of a run defender Griffen has been over the years and how teams started to run the ball more in his direction at times last season. His consistency is worth watching for another reason: if he plays at least 56 percent of the Vikings' snaps and posts at least six sacks this year, his contract voids and he will be a free agent after the season.
Anthony Harris: The safety received plenty of recognition after the game, but it's hard not to single him out here for his role in corralling the Falcons' passing game on Sunday. Harris' two interceptions highlighted what the Vikings like about him — he was in the right place to make a play on Julio Jones in the first quarter, when he converged on a high throw and took it away from the receiver, and he made an exceptional play to snatch Ryan's ill-fated third-quarter throw in the back corner of the end zone, almost looking like the receiver Ryan had intended to hit after Luke Stocker stopped his route. Those two picks, and his fumble recovery, could have Harris in line for NFC Defensive Player of the Week honors, but the fact he made the plays without taking unnecessary chances on defense was just as important to the Vikings.
Three areas of concern:
The running game (yes, actually): If you're in the mood to pick nits with the ground game (and you can bet the Vikings coaches noticed it while reviewing film last night), the team's gaudy running totals were dressed up quite a bit by how many explosive runs they had. Dalvin Cook, who gained 111 yards on 20 carries, got 70 of those yards on four runs, and had 11 carries that went for two or fewer yards. Alexander Mattison, who gained 49 yards on nine attempts, got 40 of them on two carries. Especially given how much the Vikings struggled to produce big plays on the ground last year — they only had seven runs of 20 yards or more all season — they're certainly appreciative of a run game that can break off a game-changing run from time to time. But they'll also have days where they need more drive-sustaining runs that net four or five yards at a time than they got Sunday. As Mike Zimmer noted after the game, the Falcons' defensive scheme means they usually have a safety near the line of scrimmage, creating an eight-man box to run against. But the Vikings will nonetheless look for more consistency out of their run game to go with the big plays.
Pass protection: This didn't gain much attention because of how little they threw the ball and how large their lead was. But Kirk Cousins, who was charged with nine fumbles last year, had two on Sunday, with the second one coming when Grady Jarrett beat Pat Elflein and stripped the ball out of Cousins' hand. Jarrett also bull-rushed Garrett Bradbury for a hit on Cousins on a first-quarter play that was nullified by pass interference, and a holding penalty later on the drive helped the Vikings pick up a first down after pressure around both edges of the line forced Cousins out of the pocket. Given how disruptive the Packers' pass rush was last Thursday in Chicago, the Vikings will have a tough test awaiting them on Sunday at Lambeau Field, and things could be especially difficult for players like Elflein and Bradbury with Packers tackle Kenny Clark.
Mackensie Alexander's health: While the cornerback will have a MRI on his dislocated right elbow on Monday, it's possible the Vikings will be without him on Sunday against the Packers, which makes Mike Hughes' health an especially important topic this week. The Vikings ruled him out for the game after he practiced last week, and Hughes is still working his way back from the ACL injury he sustained last October. But if he's able to go on Sunday in Green Bay, it would put a capable slot corner back in the Vikings' lineup at the point they might be without Alexander. They'd have to decide whether they wanted to put Hughes back in a substantial role right away — and they'd have to determine if his knee was ready for the demands of the nickel corner spot, with all of its lateral movement and changes of direction. But even if they're able to use Hughes sparingly, it'd give them an important piece if Alexander is out. The Vikings resorted to more zone coverage in the second half on Sunday, when Jayron Kearse took much of the playing time in the slot once Alexander left.
Three trends to watch:
Irv Smith/C.J. Ham: The Vikings made frequent use of both players on Sunday, though Smith was employed largely as a blocker; the second-round pick didn't have a catch in his first NFL regular-season game on Sunday, where he played 26 snaps. But the Vikings were able to make use of the tight end as a slot receiver on a number of occasions, including on Cook's 22-yard run in the second quarter, when Smith had a nice downfield block after Cook stepped through the initial hole between Josh Kline and Brian O'Neill. It'll be a busier year for Ham than it was in 2018, when the fullback only reached 20 offensive snaps in one game. On Sunday, he played 22 snaps and carved out a key role as a lead blocker on several of the Vikings' big runs (including both of Mattison's long gains).
