SEATTLE — This is what the Giants do. They give you agita. It’s who they are, like it or not. And it’s not likely to change anytime soon. 

This, of course, is not good for anyone’s health. Not Giants owners John Mara and Steve Tisch. Not head coach Brian Daboll or general manager Joe Schoen. And certainly not Giants fans. 

But the Giants are now eight games into the Daboll-Schoen regime and the common denominator to these games has become quite clear: Every single one of them is a three-hour, three-antacid nail-biter that’s likely going to be decided by a touchdown or less. 

The Giants aren’t an uber-talented group. They won’t have a lot of players voted onto the All-Pro roster. Save for rejuvenated (and finally healthy) running back Saquon Barkley, they’re not a team with a lot of stars. 

And yet somehow here we are through eight games after Sunday’s 27-13 loss to the Seahawks before a raucous 68,921 at Lumen Field: The Giants head to their bye week at 6-2, one of the most unlikely stories in the NFL regardless of this loss. 

The Giants entered the game having trailed their opponents four times in the fourth quarter, winning all four times. On Sunday they entered the fourth quarter trailing the Seahawks 13-10. 

This time they lost. 

They were never going to win all of these things. 

Any Giants fan who was told before this season began that the team would be 6-2 as it entered the bye week would have signed for that with their own blood. Any Giants fan that told you anything different would have been either fibbing or simply delusional. 

Sometimes, the other shoe drops. On Sunday for the Giants, it dropped. 

Call it a correction. The Giants, for all of the guile they’ve shown this season in the clutch and all the well-coached moments that have been on display, were probably due for one of these to go the wrong way on them. 

“I’m still happy about where we’re at,’’ Giants defensive lineman Leonard Williams said. “We have no reason to hang our heads. That was a good team that we just played. We didn’t lose against any slouches or anything like that. We’ve got to go back Monday and figure out why we didn’t win a game like this that we count on winning.” 

For a while, it looked like the Giants might pull yet another one of these fourth-quarter games out. They tied it at 13-13 early in the fourth quarter on a 45-yard Graham Gano field goal. 

That’s when Seattle quarterback Geno Smith, the former Jet and Giant who’s been maligned for most of his career as a castoff backup, took over the game, completing 5 of 5 for 75 yards on the go-ahead drive, climaxing it with a 33-yard strike to Tyler Lockett with 9:18 remaining. 

Then the Giants did things they’ve not been accustomed to doing on this magical ride through the first seven games: They made back-breaking mistakes that sabotaged their chances of engineering yet another comeback. 

With the Giants trailing just 20-13 and about to get the ball back, their punt returner Richie James fumbled away his second return of the day. He was separated from the ball by Seattle’s Travis Homer and the ball was recovered by Seattle’s Will Dissly with 6:04 remaining in the game. 

Two plays later, the Seahawks capitalized with a 16-yard scoring run by Kenneth Walker for a 27-13 lead. 

In the second quarter, James had the ball knocked loose by a Dissly hit, a turnover that led to a Seattle field goal and a 10-7 lead. 

“Taking care of the ball is one of our main goals and obviously we didn’t do it,’’ Daboll said. “The ball is important. We have to do a better job of taking care of it. Richie knows you’ve got to take care of it and that’s the game. Turn the ball over on your side of the field, it’s tough. So, we have to fix that.’’ 

If Daboll and the Giants took anything out of Sunday it’s that there’s much to fix, that while the 6-1 record entering the game wasn’t a mirage, it also wasn’t the complete truth about who this team is. 

Sunday was a disappointing day for the Giants, but not one that should be followed by panic. It was a correction. The Giants were never really as good as the 6-1 record they brought with them to Seattle. 

And yet still, with the Texans, Lions and two games with Washington still remaining on their schedule, a playoff berth, thought to be improbable at the start of this season, is hardly out of reach or out of the question for them.
