Thin margin of error has Gang Green laser-focused

The Jets have spent the past week trying to forget their nightmare game in Kansas City and turn their attention to Sunday’s game with the Seahawks.

“We had a bad game last week,” veteran linebacker David Harris said. “We know that. Of course we would like to be 3-0 right now, but we’re not. We’re 1-2. We have to keep fighting.”

Facing a difficult schedule in the coming weeks, this game looms large for the Jets. Cornerback Darrelle Revis even labeled it a “must-win.” The Jets travel to Pittsburgh and Arizona after facing the 2-1 Seahawks, so the pressure is on to get a win. It won’t be easy. Despite some early season struggles on offense, the Seahawks arrive at MetLife Stadium boasting the top-ranked defense in football — which has not given up a passing touchdown this season. Quarterback Russell Wilson is nursing a knee sprain, but is expected to play. Seattle has been remarkably consistent since 2012, and the Jets have not beaten the Seahawks since 2004.

“This is a week where we have to be on point,” wide receiver Brandon Marshall said. “This is a really good defense that plays together, but they also have really good guys. They have Pro Bowl players. This is going to be a great challenge for us in our backyard, but we’ve got to protect [our] home field and escape with a victory.”

It starts with quarterback Ryan Fitzpatrick, who threw six interceptions in the 24-3 loss to the Chiefs last week. Jets coach Todd Bowles was blunt this week when asked why he believes Fitzpatrick will play better Sunday.

“He can’t play any worse, and we can’t coach it any worse,” Bowles said. “There’s nowhere to go but up.”

Fitzpatrick will be without wide receiver Eric Decker, who has a partially torn rotator cuff in his right shoulder. That will complicate things for the offense. Fitzpatrick said he believes facing a defense as talented as the Seahawks helped preparation this week. Seattle is allowing just 6.5 yards per catch.

“It almost makes us better,” Fitzpatrick said. “It makes us understand that we’ve got to execute perfectly with the things that we do. We can’t miss our chances when we have them. You try to have the attention to detail every single week. I think if anything we see it as a great challenge. If anything, it makes us a little more focused.”
