Week 1 of the 2021 NFL season is officially in the books. Sixteen teams logged wins. Sixteen others fell short. But what did we learn about each of the 32 after one game of action? We're so glad you asked. As Week 2 draws near, here's a look at one thing we took away from each team thanks to the opening weekend of football:
Whatever Kliff Kingsbury concerns you may have, Kyler Murray is still a problem. For opponents, that is. Chandler Jones stole the show with five sacks, but No. 1 alone could keep Arizona in the hunt for a surprise division title.
Despite the arrival of new coach Arthur Smith, their offense is lifeless, and that includes longtime QB Matt Ryan, who was practically left a mangled mess against the Eagles -- literally face down in the turf -- after getting little help from his O-line.
Concerns about their offense are warranted. Lamar Jackson remains one of the NFL's deadliest weapons, but he faced a ton of pressure against the Raiders and fumbled twice while, perhaps, overcompensating for moving parts up front and in the backfield.
Despite all the Super Bowl hype, they might actually be candidates for regression. It's early, but what if 2020's 13-3 finish and Josh Allen MVP candidacy represented the peak? Allen and Sean McDermott both made some questionable decisions against Pittsburgh.
Sam Darnold is probably an upgrade at QB. Or at least from what Teddy Bridgewater was in 2020. There's time for this to change, but the ex-Jets signal-caller looked athletic, smooth and, best of all, confident in a close game.
We already knew it, but Sunday night's loss confirmed it: Justin Fields deserves to start at QB. Not because Andy Dalton was horrible against L.A., but because Fields, in limited snaps, is far and away the superior athlete/prospect.
After an offseason of both cautious optimism and mild skepticism, Joe Burrow hasn't lost a step coming off a serious knee injury. The young QB was poised against the Vikings, especially when Cincy needed him the most.
After going blow for blow with -- and, for a while, leading -- the reigning AFC champion Chiefs, they proved 2020 was not a fluke. The Browns are a balanced contender and will be a tough out all year long.
With a solid supporting cast around him, Teddy Bridgewater is the clear QB1. He was always a safer play than Drew Lock, his camp competition, but he looked both poised and elusive in the pocket against the Giants.
They will not be pushovers. How else do we interpret them pulling within one score of the 49ers (and dropping 33 on them!) in the first outing of the Dan Campbell-Jared Goff rebuild regime?
All that offseason drama, and Aaron Rodgers is suddenly cause for concern. A rebound may -- and likely will -- come in short order, but man, did No. 12 have the most anticlimactic season opener in recent NFL history. Who's to say all that time away from the team this summer didn't actually affect his chemistry and/or mental preparation for the new year?
Thanks to Tyrod Taylor and a band of veteran misfits, they might not be the worst team in the NFL. Look what happens when you have nothing to lose!
Their training camp COVID issues took a toll. Not sure how else you describe Frank Reich's offense looking so "meh" against Seattle's defense; new QB Carson Wentz, who missed plenty of practice time, was fine but unspectacular.
Simply having Trevor Lawrence does not mean Urban Meyer will win. And Lawrence himself doesn't look especially comfortable, either. Buckle up, Jags fans.
Kansas City Chiefs
Sorry, but it has to be this: Patrick Mahomes remains king. However imperfect he and the Chiefs start, he is always good for a thrilling and seemingly effortless comeback.
Las Vegas Raiders
It took a crazy fourth quarter and overtime to confirm it, but they might have something at wide receiver. Darren Waller still dominated as Derek Carr's favorite target in a wild upset of Baltimore, but Bryan Edwards' emergence was something else.
No surprise here, but Justin Herbert is still that guy. In a lower-scoring game, he still led big gains and, best of all, played smart when it mattered most for the win.
The Matthew Stafford hype is warranted. The QB wasn't perfect in his Rams debut, but he repeatedly hit on big-time throws to make pretty light work of Chicago.
Color Vikings fans surprised: The offensive line is still an issue. Kirk Cousins didn't always help matters against the Bengals, but the trenches were consistently a source of trouble, whether via penalties or poor blocking.
Regardless of the final score, Mac Jones was right to be declared QB1. The rookie just has a feel for the game, and things should only get better from here.
Jameis Winston is a thing. Seriously, what else is there to say? Five TDs per game is not sustainable, but boy did Drew Brees' overlooked successor look comfy airing it out against the Packers.
New York Giants
Their defense was probably overrated. Most of us already figured Daniel Jones is probably not elite material under center; fewer of us figured Patrick Graham's unit would let Teddy Bridgewater look like Patrick Mahomes.
Zach Wilson can have all the electricity in the world, but the offensive line is, in fact, a mess. That's made worse by Mekhi Becton's injury, but it was apparent in how little room Wilson's backfield counterparts had to run.
This one's especially for the jokers who clowned him because of his opening press conference: Nick Sirianni has the juice. He had the Eagles cool and confident, easily routing the Falcons in their own stadium.
Thanks in large part due to their still-stingy defense, they can't be counted out. After an offseason in which most assumed they'd fall behind the Browns and Ravens, they just beat one of the AFC favorites.
San Francisco 49ers
They need reinforcements in the secondary. That should've already been clear coming in, but with Jason Verrett down and the Lions threatening a comeback, they're on high alert.
Whatever your feelings about their defense, the Shane Waldron offense looks like a match. Russell Wilson airing beautiful bombs to Tyler Lockett, with Chris Carson still active on the ground? That's a "W" nine times out of 10.
At 44, Tom Brady might actually be in his prime. Sounds nuts, but not if you watched him uncork all kinds of pretty (and clutch) throws in Tampa Bay's first win post-Super Bowl.
Their offensive line might be in big trouble. Longtime left tackle Taylor Lewan just got eaten alive by Chandler Jones, but what if he's also just permanently on a decline? He just turned 30 and is less than a year removed from an ACL tear.
Washington Football Team
Their gamble on Ryan Fitzpatrick was always really risky. Maybe Taylor Heinicke will step in admirably, but no one should've ever expected a smooth ride after giving the keys to a 38-year-old journeyman with an injury history.
