This feels like a total mismatch again for the Jets, but funny things happen each week in the NFL. I think Sam Darnold gives the Jets a big boost on the field and in morale, and they pull off the upset for their first win of the season.

Jets 24, Cowboys 21

Cowboys offensive line vs. Jets defensive line

This matchup pits the sixth-best rushing offense in the NFL (averaging 140.8 yards per game) against the league’s seventh-best rushing defense (allowing an average of 87.5 yards per game).

The Cowboys have one of the best offensive lines in football but may be without two of their stalwarts. Tackles Tyron Smith and La’el Collins did not practice this week and both are listed as questionable.

The Jets know with or without those guys they are in for a fight.

“All great offensive linemen want to establish a good run game,” defensive end Leonard Williams said. “That’s the one thing we have to stop.”

Ezekiel Elliott has been a beast behind this line. He has 386 yards rushing and four touchdowns. The Jets have done a good job against the run this year — led by Leonard Williams, Steve McLendon and Henry Anderson. Anderson is not going to play, but rookie Quinnen Williams should make up for his loss. The Jets have allowed just 100 yards rushing once this season, in Week 1 to the Bills.

Over the line: The Jets’ offensive line has been awful this season. The return of Sam Darnold should help, but he is not going to cure the problems. The Jets gave up 10 sacks last week in Philadelphia and now face DeMarcus Lawrence, one of the best pass rushers in the league.

The Jets are expected to go with the same five starters they played last week, when rookie Chuma Edoga started at right tackle and Alex Lewis started at left guard.

“We’re confident, it’s a process and we are not where we want to be, but we are making headway,” offensive coordinator Dowell Loggains said. “I thought Alex stepped in and played really well for us, and Chuma has been showing a lot of things over the last couple of weeks that gave us enough faith in him to put him out there.”

‘O’ wow: The Cowboys come to MetLife Stadium with the No. 1 offense in football. They are averaging 452.8 yards per game and 26.2 points per game (ninth best). They are No. 4 in passing offense and No. 6 in rushing offense.

Quarterback Dak Prescott, running back Ezekiel Elliott and wide receiver Amari Cooper lead an attack that will be a huge challenge for the Jets defense.

Asked what stands out to him about the Dallas offense, Jets coach Adam Gase read his long list.

“Yeah, probably their Pro Bowl offensive line, probably one of the best running backs in football, explosive wide receiver, good slot wide receiver, Hall of Fame tight end, quarterback’s pretty good, outside of that,” Gase said jokingly.

Adams attack: There have not been many positives for the Jets this season, but one has to be the play of safety Jamal Adams. He is ranked No. 3 at his position by Pro Football Focus and has been a force all over the field.

As good as Prescott has been this year, he has thrown six interceptions. Adams might be able to notch his second pick of the season.

“I think he is playing at a very high level, he makes a lot of plays,” Gase said. “This last game, we talked about it, it’s probably the cleanest game he’s played since we’ve been here. He was on it, and he was for four quarters.”

Where’s Robby? No one has been more affected by Darnold’s absence than wide receiver Robby Anderson. The Jets’ No. 1 target has been an afterthought with Luke Falk playing. Falk does not have the arm strength to hit Anderson downfield like Darnold does. Anderson has just 11 catches for 131 yards and no touchdowns through four games.

“It’s not his fault, he’s open, he’s open, we just haven’t been able to get him the ball, something’s always happened,” Gase said. “He’s doing a good job as far as what we are asking him to do. We have had opportunities, we just haven’t hit on them yet.”
