EAST RUTHERFORD, N.J. — The Super humbling of the highest-scoring team in NFL history began on the first play from scrimmage and continued pretty much unabated for the remainder of a deceptively warm and beautiful February evening just off Exit 16W of the Jersey Turnpike.

It was shocking in its suddenness and humiliating in its comprehensiveness. The Broncos played like a pickup squad that met for the first time an hour before kickoff.

The first outdoor Super Bowl in a northern climate turned out to be a travesty all right, but the environmental conditions were the one factor the Broncos couldn’t blame. The temperature at kickoff was 49, fully 10 degrees warmer than the coldest Super Bowl on record, back when they used to play outdoors in New Orleans.

If Mother Nature treated the Broncos well, she was alone. The Seattle Seahawks manhandled and dismantled them in every way imaginable on their way to a 43-8 blowout. Give them credit, as the Broncos kept saying afterward, but blame the Broncos, too. Their early wounds, the ones that set the doleful tone, were self-inflicted.

It began on the first play from scrimmage, when the Broncos’ first snap from their own 14-yard line sailed past Peyton Manning into the north end zone of MetLife Stadium. Somehow, the Broncos were lulled by the neutral site into believing they would be able to convey their signals verbally. Had the game been in Seattle, they would undoubtedly have used a silent snap count. Buried deep in their own end, enveloped by the boisterousness that always accompanies the beginning of a Super Bowl, Manning lined up in the shotgun and called for the ball.

Center Manny Ramirez failed to snap it. So Manning walked toward the line to reset the play. Ramirez, suddenly realizing he was late, chose that moment to snap the ball.

“That was on cadence, so it was about what he was saying,” a miserable Ramirez explained afterward. “It was really loud and I (thought) I heard him. Unfortunately, I was three seconds late.”

“A little bit of a cadence issue,” said head coach John Fox.

“I felt terrible for them,” said Seahawks coach Pete Carroll. “We didn’t deserve that. They just gave it to us.”

Running back Knowshon Moreno hustled back to the ball, turning the faux pas into a safety rather than a touchdown. It was a screw-up, but the damage was minimal. Twelve seconds into the game, the score was 2-0. It was the fastest score in Super Bowl history.

“That’s the way the start of any Super Bowl is,” said receiver Wes Welker, a veteran of three. “It’s going to be loud. The fans are going to be yelling. They don’t really know why they’re yelling, it’s just the start of the Super Bowl. We didn’t prepare very well for that, and it showed.”

Imagine that. A team that prided itself on preparation all season was unprepared for something that seemed obvious to a player who had been there before.

Following the required free kick, the Seahawks’ lightly-regarded offense marched 51 yards on its first possession, converting two third downs along the way. The Broncos again managed to minimize the damage, stopping the Seahawks about six inches short of a first down inside the 10-yard line and forcing a field goal. When Manning & Co. got the ball back, it was still only 5-0.

Following a three-yard gain on a running play, Manning completed the first two passes he threw — for two yards to Demaryius Thomas and three yards to Julius Thomas. Two completions, five yards. They had to punt.

The Seahawks began another march, using up most of the remainder of the first quarter. The Broncos’ defense once again limited the damage near the goal line, forcing another field goal when linebacker Nate Irving knocked an apparent touchdown pass out of the hands of wide receiver Jermaine Kearse.

The first quarter wasn’t over yet and the Broncos had already prevented two touchdowns on hustle plays by Moreno and Irving. Despite a disastrous start, the score was a manageable 8-0.

For the third time, Manning took the controls. For the third time, the crowd waited for the precision passing game that produced a record 606 regular-season points. A five-yard completion to Welker. A three-yard run from Moreno.

But wait. When Moreno was stopped, he was still on his feet. Seahawks defensive end Chris Clemons ripped the ball from his grasp. Guard Zane Beadles made the Broncos’ third fortuitous play of the quarter, falling on the loose ball and preventing a turnover. Instead of third-and-2, now it was third-and-7.

Manning tried to convert it by hitting Julius Thomas, his tight end, up the middle, but Seahawks pass rusher Cliff Avril came around right tackle Orlando Franklin on a speed rush and Manning was forced to step up in the pocket to avoid him. He let loose a throw that wasn’t even close to its mark — a duck, as Seahawks cornerback Richard Sherman would call it, both too high and behind the intended receiver. It landed gently in the arms of Seahawks safety Kam Chancellor, a room service interception.

“A poor play on my part,” Manning admitted afterward.

When the first quarter ended, the Seahawks had the ball at the Broncos’ 17-yard line on their way to a 15-0 lead. The Broncos had possessed the ball only momentarily, it seemed, mostly because they were in such a hurry to give it away whenever they did.

Yet another self-inflicted wound contributed to that first Seahawks touchdown. The Broncos defense, again playing damage control near its goal line, forced a third-and-4 from their 5-yard line. It was looking to limit Seattle to another field goal when nickel back Tony Carter face-guarded Seahawks receiver Golden Tate in the end zone while gripping his jersey, possibly the most obvious pass interference call of the season. This resulted in a first down at the 1. It still took the Seahawks two running plays to punch it in.

Three minutes into the second quarter, the most prolific offense in NFL history didn’t have a first down. Credit the Seahawks’ hard hitting or pass rush if you like, but if this was tennis, both the bad snap and errant throw would be ruled unforced errors.

Moments later, the Seahawks lived up to their reputation for creating turnovers. Avril again beat Franklin, this time pushing past him and hitting Manning’s arm as he threw. The ball fluttered like . . . well . . . yes . . . a wounded duck, directly into the arms of Seahawks linebacker Malcolm Smith, whose 69-yard return for a touchdown would be the key to his Super Bowl MVP award a couple of hours later.

Now it was 22-0. Slightly more than three minutes remained in the first half. The Broncos desperately needed a score. Slowly, uncertainly, they began to matriculate down the field, in Hank Stram’s famous phrase from another era. They achieved a first down. Then another. Facing a manageable third-and-4 for yet another, Louis Vasquez, their best offensive lineman, was called for a false start. Yet another error. Maybe Seattle’s fearsome foursome made him do it, but still.

Moments later it was fourth-and-2. Fox decided to go for it.

“I’m thinking that three points wasn’t going to make a big difference in the game, and it proved to be true,” he explained.

At the snap, it looked like an uncovered Julius Thomas signaled to Manning for a simple pitch-and-catch that would move the chains. Instead, Manning looked the other way and threw the ball into the ground at the feet of Demaryius Thomas.

In the press box, in the stands, on social media and in living rooms all over Colorado, people who had watched this offense operate like a jet engine all season watched in astonishment as it sputtered like a lawn mower. Who were these guys?

It wasn’t just that the Broncos had switched hotels the night before the game, they appeared to have switched players, too. The replacements looked a lot like the guys they’d replaced. They even wore the same numbers. But they didn’t play anything like them.

The cherry on top came on the first play of the second half. Matt Prater, the Broncos’ Pro Bowl kicker who led the league with 81 touchbacks, inexplicably pooched the kickoff in an apparent attempt to keep it out of the hands of returner Percy Harvin. Kicking it out of the end zone, which Prater had done more often than any other kicker, would accomplish the same result.

Harvin had rushed twice in the first half for 45 yards. Rather than match strength with strength and let Prater try to boom the kickoff across the Hackensack River, the Broncos got cute. Harvin charged out of the end zone and the pooch bounced directly into his hands. Members of the Broncos’ coverage unit converged and knocked each other down as if playing electric football. Harvin took it all the way for a touchdown, 87 yards in all.

The Seahawks had again scored just 12 seconds into the half. This would converge with the narrative surrounding their 12th man — their fans, who arguably influenced the mistake that led to the first 12-second score — into a sort of mythic sense of numerological destiny.

More to the point, it was now 29-0 and the Broncos had shown themselves to be vulnerable in every phase of the game. No team had overcome a deficit greater than 10 points to win any of the previous 47 Super Bowls. At 2-0, 5-0, 8-0, 15-0, a Broncos comeback still seemed plausible, given their own precedents. Even at 22-0, a miraculous comeback from a team that averaged 37.9 points a game in the regular season seemed possible.

But the Harvin kickoff return dashed whatever hope remained. Not only was a 29-point deficit an insurmountable obstacle against the league’s best defense, the Broncos had shown little sign of even elementary competence. The more pertinent question seemed whether the Seahawks could impose the first shutout in Super Bowl history.

“We just weren’t real sharp executing our offense,” Manning said in perhaps the understatement of the season. “We got ourselves in a hole and we weren’t able to overcome it.”

Once the game was out of hand, the Broncos managed to roll up enough meaningless yards to make the final statistical comparisons look benign. In fact, of the six Super Bowl records set Sunday, four were by the Broncos. Of course, one of them was for most Super Bowl losses (five), which is not a record you want to hold. But Manning’s 34 pass completions were a record, as were Demaryius Thomas’ 13 catches. They were as hollow as any Super Bowl records ever set.

The Seahawks set records for fastest score to start a Super Bowl and most time playing with a lead (59 minutes, 48 seconds).

The cumulative record for losses in the big game might seem fastidious, conflating a 21st century result with games played in the 1970s and ’80s, but this one was eerily reminiscent of those losses in the ’80s, when the Broncos won the AFC in three out of four seasons and were blown out by successively larger margins in the ensuing Super Bowls — 39-20 by the Giants following the ’86 season, 42-10 by the Redskins following the ’87 season and 55-10, the worst blowout in Super Bowl history, by the 49ers following the ’89 season.

In each case, the result was disturbing and dispiriting. The Broncos had gone through a long season and postseason with the look of a champion, only to look utterly overmatched in the most important game of all. It’s hard to know how to react to such a dramatic reversal of fortune.

“I think we were playing a great football team,” Manning said. “I think we needed to play really well in order to win and we just didn’t come anywhere close to that . . . . Give Seattle credit. They’re an excellent football team and they caused a lot of our mistakes. But at the same time, we just didn’t play well tonight.”

Twenty-four hours after winning his record fifth Most Valuable Player award, Manning bristled when asked if the loss was embarrassing.

“It’s not embarrassing at all,” he said. “I would never use that word . . . The word embarrassing is an insulting word, to tell you the truth.”

Welker was not so reticent.

“To get this far and lose like this, it’s embarrassing,” he said.

“They dominated us across the board,” said fellow receiver Eric Decker.

The Seahawks were exuberant, of course, having won so much more powerfully and easily than even they expected. The Broncos needed to credit them to save face, and certainly they kept Manning unsettled in the pocket and hit hard in the secondary, as is their reputation.

Still, the number of self-inflicted wounds made the Broncos look amateurish and unqualified for the game. They finished with four turnovers — two lost fumbles and two interceptions — to Seattle’s none. The third turnover, by Demaryius Thomas following a 23-yard, third-quarter completion deep in Seahawks territory when a comeback was still theoretically possible, verged on slapstick.

Which was a terrible shame, considering how well the Broncos played all season. You could empathize with Manning’s sense of dignity without agreeing with him that this was not an embarrassment.

On any given Sunday, and all that. They just picked the most important game of all to pull out a true stinker.

“We had some chances to get back into it,” said John Elway, the quarterback in those losses of the ’80s and now the team’s executive vice president of football operations. “We just couldn’t get it done.”

“This team used last year’s playoff loss to fuel us; I think it made us a better team,” Manning said. “Hopefully we can use this loss to fuel us and make us better.”

Maybe they will. Elway’s Broncos were unable to bounce back from the Super Bowl blowouts of the ’80s until nearly a decade later, but Manning’s team was so uncharacteristically bad, maybe it can turn this one around much faster.

Asked if the loss reminded him of those blowouts a generation ago, Elway replied: “No. Those are separate.”

Still, for all the praise Manning gets when he’s dominating opponents, it is only fair to point out his mediocre play when opponents dominate him. The Broncos’ oft-maligned defense wasn’t great in this game, but it was required to perform a great deal of damage control for its far more famous offense.

Manning completed 34 of 49 passes for 280 yards, many of them in garbage time, with one touchdown, two interceptions and a passer rating of 73.5. His counterpart, second-year Seahawks quarterback Russell Wilson, the former Rockies farmhand, was 18 of 25 for 206 yards, two touchdowns, no interceptions and a passer rating of 123.1. Wilson was clearly the better quarterback in this championship game.

“Offensively, we were clicking on all cylinders,” Wilson said. “That’s what we wanted to be, especially the last game of the season, to finish that way in that fashion. That’s our mindset. We want to be champions every day and bring it every time.”

Credit the Seahawks for playing a very sharp game. They deserve congratulations on winning their first NFL championship in very convincing fashion.

“We ran into a buzz saw,” Fox said.

That’s a little too easy. The Seahawks played very well, but the Broncos took themselves out of the game early by playing very badly. From a vantage point high above the action on a beautiful night for football in the New Jersey Meadowlands, it looked like the highest-scoring offense in NFL history mostly self-destructed.
