Even in the darkest days of the last miserable decade, the Giants usually could count on beating the Commanders in a matchup of the downtrodden.

Consider the snowstorm Sunday morning a sign of apocalyptic times because the Giants have sunk so far into the bottom of the NFC East — and the bottom of the NFL — that they can out-mistake the bumbling Commanders and lose 29-21 in a game between teams who entered with a combined 15 straight losses.

“Just another Sunday,” Brian Burns said after the Giants’ losing streak reached eight straight.

Playing in front of a half-filled MetLife Stadium, with snow piles pushed up against the wall separating the field from the stands, the Giants could not overcome a Jaxson Dart interception and more missed snaps for a concussion test, two Younghoe Koo missed field goals, two drops by Darius Slayton, head-scratching decisions by interim coach Mike Kafka and defenders who were even not in the right zip code on two touchdowns.

“We want to put out a product that the fans are proud of,” a disheartened Andrew Thomas said, “and obviously we’re not doing that, so that’s why they are not there.”

How many fans who braved the conditions even wanted to see a win when the loss allowed the Giants to hold onto the No. 1 pick in the 2026 NFL Draft for another week?

You never would have guessed by the first half that the Giants (2-12) were favored in the game for the first time in 13 months — since Daniel Jones’ last game in the uniform (a loss to the Panthers in Germany). The Giants haven’t won as a favorite since Week 2 of the 2023 season — a 21-point road comeback in Arizona — and share the NFL’s worst record (11-37) over the past three seasons.

“Our guys just have to keep on fighting,” Kafka said. “That’s what we’re going to need. That’s what it’s going to take to get over the hump and get a W.”

It was one thing when the Giants — who were 7-2-1 against the Commanders (and 22-51 against the rest of the NFL) from 2019-23 — were swept by the NFC Championship game-bound Commanders last season. But to lose a fourth straight in the series, with journeyman backup quarterback Marcus Mariota at the controls to snap an eight-game losing streak, is another level of incompetence.

How did it happen?

The Commanders (4-10) had no trouble moving up and down the field on three of their first four possessions for 176 yards of offense, 10 first downs and a 13-0 lead.

Add in a disastrous final 80 seconds of the first half that started when Cam Johnston — signed to the practice squad last week and elevated to replace the injured Jamie Gillan — had a punt returned 63 yards for a touchdown. It was the second time in as many games that special teams coordinator Michael Ghobrial’s unit has allowed a score.

Trying to answer back, Dart threw an interception that was returned 55 yards. It flipped field position from the Giants being on the edge of field-goal range to the Commanders converting a chip shot on the final play of the first half as the deficit grew to 22-7.

“I take accountability for this one,” Dart said. “I didn’t play well enough today for this team to win.”

Or consider this sequence spanning the final two quarters when the Giants were trailing 22-14:

John Michael Schmitz was called for a personal foul penalty to turn second-and-5 into second-and-20, Slayton could not hang onto an over-the-shoulder touchdown catch after slipping behind the defense, Kafka called a run on third-and-20 and Tyrone Tracy Jr. gained just 2 yards as the third-quarter clock expired.

“[Officials] said that it was like a headbutt, kind of just helmet-to-helmet type thing,” Kafka said of the Schmitz penalty that sent everything askew. “Just have to be smart there. Obviously, can’t have those penalties.”

And then, Koo missed a 51-yard field goal by about a mile into the same end zone where he missed earlier and struggled during pregame warmups.

“I hit the ball exactly the way I wanted — it was just the conditions,” Koo said. “The first one, I went to drive it a little more and I did, but it didn’t move the way I anticipated. The second one got caught up there. I think I had the leg to get it there, but those are makeable kicks. I have to make them.”

The Commanders extended their lead to 29-14 on Terry McLaurin’s 51-yard touchdown as he spun around Dane Belton and was left with more real estate than Jacory Croskey-Merritt had on his walk-in 16-yard touchdown run in the first half.

But the Giants had three more possessions: a turnover on downs at the 4-yard line when Dart missed two snaps while getting checked for a concussion for the fifth time this season (four passed), a fourth-down 16-yard touchdown pass to Wan’Dale Robinson to make things interesting and another turnover on downs.

The defense actually gave the Giants life because Dane Belton and Abdul Carter each forced two fumbles, with two of the four loose balls leading to takeaways in the final six minutes.

But Dart’s last pass fluttered incomplete with 97 seconds remaining.

“Today, in the red zone, we were terrible,” Thomas said. “We left a lot of points out there, which didn’t help us.”
