Three areas in which Jets have improved from last season and three areas of concern

Aaron Glenn doesn’t bring the same hype as Aaron Rodgers. The only thing the Jets and their fans care about is whether Glenn can produce more wins.

The Jets won only five games last year despite being hailed as Super Bowl contenders entering the season. Vegas oddsmakers put the over/under for this year’s Jets at 5.5 wins.

The Glenn era officially begins Sunday at MetLife Stadium against Rodgers and Pittsburgh. Here are three areas in which the Jets have improved from last season and three question marks heading into Week 1:

THE GOOD

Stability: Glenn has brought that much-needed aspect to the Jets after a tumultuous 2024.

Former coach Robert Saleh was on shaky ground heading into the season. It was widely believed that he would need some playoff wins to return for a fifth season. Saleh was fired with the Jets at 2-3. Players were stunned and the Jets never recovered.

Glenn is very much in charge of the operation now. He has the full support of owner Woody Johnson. The players know that and believe in him. They will play hard for Glenn and follow his lead.

The running game: This should be a major upgrade with the addition of quarterback Justin Fields along with the system that coordinator Tanner Engstrand and the blocking scheme that offensive line coach Steve Heiden brought with them from Detroit.

The Lions were sixth in rushing yards and third in rushing touchdowns last season. The Jets were 31st in both.

Breece Hall, underutilized last season, should have a big year. Braelon Allen could emerge as a 1A back in Year 2. Fields is dynamic running with the football. Only Lamar Jackson (57.3) has more rushing yards per game than Fields (50.2) since 2021, and Fields (19) has scored five more touchdowns than Jackson.

Defensive tackle: New general manager Darren Mougey strengthened that position during the last week of camp when he acquired run-stopper Harrison Phillips from Minnesota to play next to Quinnen Williams.

Phillips finished second in tackles among all defensive linemen two years ago with 92. Former Bengal Jay Tufele had a good camp and preseason and will be in the tackle rotation. Mougey picked up Jowon Briggs from the Browns the same day he got Phillips.

The Jets opened last season with Williams, Solomon Thomas, Javon Kinlaw and Takk McKinley as their top tackle depth. Kinlaw and McKinley were disappointments.

THE CONCERNS

The No. 2 receiver: Garrett Wilson needs someone to take double teams away from him. The Jets haven’t gotten that guy yet for Wilson — or, for that matter, Fields, whom they’re hoping to make a more complete quarterback.

Josh Reynolds knows the system, where to be and how to get open. Allen Lazard is a good blocker and a big, strong target in the red zone. Both bring value, but neither demands much attention from defenses. Rookie Arian Smith will stretch the field with his speed, but he’s not a No. 2.

The Jets are expected to use Hall prominently in the passing game. Rookie tight end Mason Taylor also could be featured. Wilson still can expect heavy double coverage.

Quarterback: Rodgers gets a lot of blame for the Jets’ underachieving season, but defensive breakdowns and doinked late-game field-goal attempts contributed. Rodgers still threw for the third-most yards and third-most touchdowns in franchise history.

Fields remains unproven as a passer in the NFL. He has only two 300-yard passing games in 44 starts and has never thrown more than 17 touchdown passes in a season.

Glenn and Engstrand believe he has untapped potential and can excel playing quarterback in this system. It’s prove-it time for Fields, who is playing for his third team in three years.

Growing pains: There is a leadership void with C.J. Mosley retired and respected veterans Morgan Moses, Tyler Conklin, D.J. Reed and Thomas Morstead with other teams. Other players, including Wilson and Sauce Gardner, have to step up.

The Jets also are starting two rookies at important positions: right tackle Armand Membou and Taylor, replacing Moses and Conklin, respectively. Membou and Taylor look as if they could develop into good NFL players, perhaps even Jets cornerstones, but there will be mistakes they have to work through and learn from this season.
