The Giants’ expectations have changed.

Brian Daboll’s players weren’t thinking like grateful underdogs who scored their third straight upset after Sunday’s 23-17 nail-biter over the Jacksonville Jaguars.

They were carrying themselves like winners who expected a lofty goal beyond this regular season, unsatisfied with the mistakes that nearly prevented them from improving to 6-1.

“Other teams might be happy right now that they got a win and they’re looking at their record, but winning teams don’t,” center Jon Feliciano said. “It’s great to win, but really, Jacksonville kicked it out. We’ll come in Monday and work on the things we have to work on.

Saquon Barkley, their offensive focal point, committed the mother of all Sunday misdeeds: He stepped out of bounds with 1:07 left, the Giants up three and the Jaguars out of a timeout. Staying indoors will keep the clock running for less than 30 seconds.

That’s why Fabian Moreau, Xavier McKinney, Julian Lowe and Landon Collins had to tackle Jaguars receiver Christian Kirk at the Giants’ 1-yard line as time expired.

“You know they’re in this situation because of you,” Barkley said, shaking his head despite finishing with 110 yards rushing.

Barkley also criticized himself for “going soft” in the first half while “thinking about the wrong things” – perhaps protecting his right shoulder.

The defense was even more disappointed in itself as they nearly wasted a dynamic day from Daniel Jones (career-high 107 rushing yards, 202 passing yards, two TDs).

McKinney called Sunday “probably our worst defensive performance.” “We’re not satisfied at all,” linebacker Jaylon Smith said after Trevor Lawrence allowed a season-high 452 yards on offense.

McKinney forced a Travis Etienne fumble at the Giants’ 5-yard line in the first half, which Julian Love recovered in the end zone. And Smith and Love jammed Lawrence on a fourth-down sneak at the Giants’ 21-yard line in the fourth quarter.

“On those stops, we knew we had to make a play for our offense,” Smith said. “Our offense did a hell of a job today, DJ moved the ball and kept us in it. We knew it was our time to make plays, do something, impact the game.

Even Jones showed frustration and significant emotion on Sunday, which is typically out of character for the Stoke quarterback but not necessarily unwelcome.

After a fourth-and-2 drop by receiver Marcus Johnson at the Jaguars’ 1-yard line, cameras caught Jones saying “catch the ball.” Another shot showed Daboll pushing QB coach Shea Tierney away from Jones to talk to the sacked QB on fourth down.

Jones felt bad if he appeared to be showing off Johnson, which was not his intention.

“The heat of the moment, and I wish I could take that situation back,” he said. “I’m proud of being composed under those circumstances. I wasn’t there. I have all the faith and trust in the world in Marcus, and yes, I’m disappointed that I let that happen.”

That’s okay, though. Because Jones’ frustration, the defense’s frustration, and Barkley’s frustrations are all coming from the best place: These Giants think they can be something this season.

“There’s an ultimate goal and we have to focus on that week in and week out,” said Smith, the veteran linebacker.

McKinney said the Giants need to improve “to get where we want to be.”

They’re not saying the word “playoffs” out loud. But after overcoming a second-half deficit for the fifth time through seven games, they ended up thinking they didn’t belong.

They see the task ahead: keep winning, improve, and brace themselves for five NFC East games in seven weeks from Thanksgiving to Jan. 8.

McKinney, in fact, didn’t want to hear the weekly question about how many doubters the Giants still have. They don’t consider themselves underdogs. They have high standards.

“I don’t even care about that question anymore,” said the safety. “I’m tired of answering it because it’s the same thing every week. Obviously we know. We really don’t care.”
