1.) The Ravens played like one of the worst teams in the league, and John Harbaugh is going to start taking real heat for it.
The Jets stink.
They had been outscored by a combined 74 points in their previous four games going into Sunday. And by advanced statistical measures such as Football Outsiders' DVOA ratings, they were even worse than the winless Cleveland Browns.
As if to remind us of this reality, they muffed a punt on their first drive of the game to hand the visiting Ravens a 7-0 lead.
Just the scenario the Ravens would have drawn up for a game they badly needed to win, right?
Yet somehow, for the rest of a depressing afternoon, the Ravens made the Jets look frightening rather than frightfully bad.
Geno Smith and Ryan Fitzpatrick combined for a passer rating that would make Joe Montana blush. Joe Flacco, meanwhile, guided the Ravens to a whopping 42 yards on 27 plays in the second half.
Against arguably the worst team in the league, they were clearly the worst team on the field. Suddenly, the idea of the Ravens contending for anything (other than another top-10 draft pick) felt ludicrous.
Every week now, John Harbaugh laments how they're not playing winning football, not translating their efforts in practice to production on Sunday.
If that's the case, the ire of a dispirited fan base is going to focus increasingly on Harbaugh himself. And according to his own description of the problem, it's scrutiny he deserves.
He'll get a very long leash from owner Steve Bisciotti, and he should. He's always won when working with talented, healthy rosters, and he's rarely failed to coax spirited efforts from his players.
I fully expect Harbaugh to coach the Ravens in 2017. But if they don't alter their fortunes rapidly, I expect to hear wide speculation about a coaching change for the first time since he took the job in 2008.
It's possible to spin the Ravens' situation as not terribly dire. Because of a 3-0 start, they're still only a game out in the AFC North. The division-leading Steelers — next up for the Ravens after their bye week— are playing without quarterback Ben Roethlisberger.
One well-timed win, and the Ravens could be right back in the mix.
But they'd have to resemble a functional NFL team to justify such optimism, and right now, they're headed in the opposite direction.
2.) Joe Flacco had the look of a shaken man.
For one fleeting moment in the first quarter, Flacco was golden. Backed against his own goal line, he froze the Jets defense with a faked play-action handoff and heaved a lovely 53-yard bomb into the arms of a sprinting Mike Wallace.
For those few seconds, it was possible to imagine a new offensive dawn, lifting on the quarterback's powerful right arm and the swashbuckling instincts of new coordinator Marty Mornhinweg.
Instead, the drive stalled three plays later, and the Ravens were on the way to perhaps their most incompetent offensive performance of the season. Which is saying something given that they already got one coordinator fired.
The injury-riddled offensive line played poorly again, creating scant running room for Terrance West and allowing too much pressure on Flacco.
Perhaps because of that pressure or perhaps because of his ailing right shoulder, Flacco played hesitantly in the second half. He fell into his chief bad habit of not striding into throws.
Flacco threw his first interception in 176 passes when he locked onto Breshad Perriman on an outside route and apparently did not see lurking Jets cornerback Buster Skrine. On the next possession, he sailed a pass well over Perriman's head and into the arms of safety Marcus Gilchrist.
On several other attempts, he missed open receivers high or wide because he seemingly threw without conviction. He threw a ball straight into the ground on the team's last drive, appearing spooked when there wasn't a defender close to him.
Perhaps the Ravens will return from the bye week with their starting offensive line, and perhaps Flacco's shoulder will feel stronger after two weeks of rest.
The Ravens better hope so, because they can't win with their franchise quarterback looking this ill at ease.
3.) The interior defensive line is this team's best feature.
The Ravens allowed too many big plays against the Jets, largely because of poor tackling on the outside and in the secondary.
But the middle of their defensive line, led by Brandon Williams and Timmy Jernigan, played another outstanding game.
Williams is the bedrock on which this defense is built, even though his efforts rarely translate to splashy individual statistics. So I always feel good for him when he produces a game like he did Sunday with eight tackles, a sack, two tackles for loss and a blocked kick. It helps remind everyone the Ravens have a star at nose tackle.
Jernigan added a sack in what's shaping up as his breakout season. He showed us flashes of greatness from the first day he strapped on a Ravens helmet. The difference now is he makes a positive impact every week.
And don't forget Williams' rookie understudy, Michael Pierce, who chipped in another five tackles and a sack.
Fans understandably assail general manager Ozzie Newsome for his uneven drafts in recent years. But they can't say the man has lost his eye for promising defensive tackles.
4) There will be calls to pull Devin Hester, but he deserves the benefit of the doubt.
I saw plenty of harsh Twitter comments about Hester after he fumbled twice (he didn't lose either) and totaled just nine return yards against the Jets.
He certainly appeared shaky after sitting out the previous week because of a thigh injury. And he's now fumbled four times in six games— deadly sins for a returner.
But it's too early to call this a failed signing.
I know Hester has yet to break a return touchdown, his signature during his Pro Bowl years with the Chicago Bears. And I know he's more clever than he is scorching fast these days.
Look at his production, though. He averaged 28.8 yards per kickoff return coming into the Jets game, which would be the second-best mark of his career over a full season. He popped off long returns against both the Cleveland Browns and Oakland Raiders, plays we've forgotten largely because the Ravens did not take full advantage of them.
Even in his diminished state, Hester offers the Ravens a threat they've not possessed since peak Jacoby Jones. And they're at a point where they can't toss aside anyone who might move the ball in 40- or 50-yard chunks.
5) The Ravens are wasting a spectacular season from Justin Tucker.
Blustery winds whipped across the New Jersey Meadowlands on Sunday afternoon, making a 50-yard field-goal attempt feel like a perilous endeavor.
Not for Tucker.
He extended his perfect 2016 with makes from 50, 49 and 44 yards. As has been the case all year, his 50- and 49-yard kicks looked like they would have been good from 60.
Remember last season, when we worried Tucker had lost something because he went 4-for-10 from 50 yards or beyond?
He says he's not doing anything different this year, but he sure seems to be hitting the ball more consistently, no matter the conditions.
It's a shame his excellence has been overshadowed by the team's overall inability to score.
