The Jets’ Week 1 win over Detroit feels like it was sometime around the Paleozoic Era. Since that dramatic opening night victory, the Jets have dropped three in a row, and looked bad doing it last week against the Jaguars.

They return home Sunday to face a 2-2 Broncos team that is dealing with a two-game losing streak of its own. It is the first of three home games for the 1-3 Jets, and they come back to MetLife Stadium in desperate need of a victory.

“Every single day you come in here and work, obviously when you lose, we’re not trying to lose, we’re trying to win ball games here,” rookie quarterback Sam Darnold said. “It obviously sucks because you put so much time into the week trying to beat these guys and then you just come up short on the weekend, during the game. That’s not what you want. At the same time, you just got to keep the same mindset, one team one goal, we’re all we got.”

Darnold has already experienced plenty of rookie growing pains. Last week against the Jaguars, he could not establish any rhythm and missed some open receivers on big plays. His defense did not help him out by allowing Blake Bortles to carve them up with short crossing patterns.

The Broncos are coming off a disappointing loss Monday to the Chiefs. Denver, with new quarterback Case Keenum, will be trying to avoid its own three-game losing streak in this game.

Jets players emphasized communication this week and starting a winning streak at home.

“They’re a very good team that runs the ball well,” nose tackle Steve McLendon said. “The biggest thing is it’s about us. It’s about the men in this locker room and what we’re capable of doing.”

On offense, the Jets need to come out with a fast start. They have scored just one first-quarter touchdown this season and have not scored on their opening drive yet.

“We’ve got to go to work and go to the field angry,’’ offensive coordinator Jeremy Bates said. “We have to have a better opening series and that starts with coaching. We have to find a way to get into a rhythm.’’

Jets right tackle Brandon Shell vs. Broncos OLB Von Miller

The Jets have seen a run of good pass rushers this season already. Now, they get maybe the best in the NFL. Miller has four sacks this season and 87.5 sacks in his career, which leads the NFL since 2011.

Miller moves around, but he primarily lines up on the offense’s right, meaning it will be on Shell to stop him. The two faced off last year and Miller had one sack.

“He is an excellent player,” Jets offensive coordinator Jeremy Bates said. “One of the best players I’ve faced. You’ve definitely got to know where he is at. he definitely changes your game plan and you definitely have to require some thinking about where he is on the field in every situation, they move him all over the place. He is a great player. He is quick with his hands, quick with his feet. He loves the game, and it’s another challenge and another good opportunity to go against a great defensive end.”

Communication breakdown: The Jets defense looked lost last week in Jacksonville, as Dede Westbrook ran wide open through gaping holes in the coverage. This week, the defense spent more time working on communication.

Safety Jamal Adams said the defense would have a players-only meeting on Friday to go over film and calls as a unit, rather than broken down by position group.

“We just need to get better,” Adams said. “I’m taking it upon myself to set everybody up as a defense so we communicate better and be better on Sundays. It’s just time. It’s time to do a little bit extra.”

The Jaguars killed the Jets with crossing routes. The linebackers and defensive backs looked confused and unsure of who they were covering. It was not all because of a lack of communication, but it was certainly a problem.

“It can always be better,” Adams said. “We just want to get better, man, and make sure we’re on the same page at all times.”

Nowhere to run: The Jets had just 34 yards rushing last week. They failed to establish any sort of ground game and that put too much on the shoulders of rookie quarterback Sam Darnold.

Offensive coordinator Jeremy Bates said it was not a game-plan issue, but they simply did not do enough on the early downs to control the ball and get the offense rolling.

“I don’t think we were pass-heavy,” Bates said. “I think we’ve just got to do a better job on first and second down so we are in manageable down-and-distance on third down. We need to execute on third down so we have an opportunity to run more plays.”

Rookies rolling: The Broncos have a pair of rookie running backs who are leading the way for their offense. Phillip Lindsay, an undrafted free agent has rushed for 267 yards and a touchdown. Royce Freeman, a third-round pick, has 219 rushing yards and three touchdowns. Denver is third in the league in rushing entering this game, averaging 148.3 yards per game.

“They have a few good backs back there,” defensive end Henry Anderson said. “No. 30 Lindsay is playing really well and with Freeman, they’re kind of split in carries and both paying really well. We’ve got to do a really good job up front with out rushing attack and force them to throw the ball.”

Home run: It would not be fair to call this desperation time for the Jets, but we’re getting close. These three home games are huge for them. The season could slip away if the slip up at home against the Broncos, Colts and Vikings.

“It’s important because you want to defend home turf, first of all, I mean you don’t want nobody walking into your stadium and beating you,” coach Todd Bowles said. “It’s important to get on a winning streak one at a time that can get us back in this season, so it’s very important.”

This looks like a close game to me. Case Keenum has not thrown a touchdown since Week 1. Sam Darnold has stumbled in recent games. Both defenses have potential. The Broncos rushing attack makes the difference in the fourth quarter.
