Costello’s call: These are two similar teams that are counting on their second-year quarterbacks to make a big jump this year. I think Sam Darnold outplays his buddy Josh Allen in this one. The Jets get off to a good start on Sunday under Adam Gase and win an entertaining game over the Bills.

Score prediction: Jets 27, Bills 20

Marquee matchup: Jets running back Le’Veon Bell vs. Bills linebacker Tremaine Edmunds

The Jets handed Bell a four-year, $52.5 million contract in March, hoping that he can spark their offense and give Sam Darnold some help. Bell did not play at all in the preseason but looked strong during training camp practices. He has not played a game in 20 months after sitting out last season during a contract dispute with the Steelers.

The question is whether he can recapture the form he showed in 2017, when he gained more than 1,900 yards from scrimmage. Bell said this week he is ready, telling coach Adam Gase not to hold him back.

“I could carry it 50 [times] if you asked me to. I’m ready,” Bell said. “When I said don’t hold back, I mean literally that. I don’t want them to go out and try to sprinkle me in or things like that. I’m ready to play football. I’ve been waiting a long time for this moment.”

Edmunds had a monster rookie season for Buffalo last year at just 20 years old. He was the only player in the NFL with 120 or more tackles, 12 or more passes defensed, two or more sacks, two or more interceptions and two or more forced fumbles. He can be disruptive.

Allen-town: The Jets’ defense has to find a way to bottle up Bills quarterback Josh Allen, who has a cannon for an arm and can beat you with his feet. Allen accounted for 18 touchdowns last year as a rookie. Against Adam Gase’s Dolphins last year, Allen ran for 135 yards in one game.

“He’s maybe 240, running out there,” Jets linebacker Jordan Jenkins said. “It’s like a smaller Cam Newton that can run the ball. I’m pretty sure his 10-yard split is just as fast as anybody’s. If you let him go vertical, he’s going to make you pay. If you have bad rush integrity and bad gap integrity when it’s a pass, he’s going to make you pay for it. If his reads aren’t there, he’s going to try to make something happen.”Allen can throw the ball a mile and is very good at extending plays. This will be a test for new defensive coordinator Gregg Williams’ unit.

Line of communication: The Jets’ offensive line played zero snaps together in the preseason. Center Ryan Kalil was signed a week into training camp and they eased him into practice. Right guard Brian Winters (shoulder), left guard Kelechi Osemele (chest) and right tackle Brandon Shell (knee) all missed time in camp. Now, the five will play together against a Bills defense that finished No. 2 overall last year.

“These guys are pros,” Gase said of his line. “They’ve been working since that group has really gotten together. Even with guys being injured or not practicing, they’ve done a great job in the classroom communicating, they do a good job communicating with me as the play-caller as far as how they’re seeing stuff.”

Kicking carousel: The Jets will trot out their third kicker in the last month on Sunday. Kaare Vedvik will kick in his first NFL game against the Bills. Vedvik was cut last weekend by the Vikings, who traded a fifth-round pick for him just two weeks prior.

Gase was a master at winning close games in Miami, going 20-6 in one-score games over his three years, the best mark in the league. Close games often come down to kickers. Can the Jets trust Vedvik? We may find out on Sunday.

D-line debuts: The Jets and Bills both drafted defensive linemen in the first round this year, with the Jets taking Quinnen Williams No. 3 overall and the Bills selecting Ed Oliver six picks later. The two will get to make their NFL debuts against each other. Both come with big expectations.

“[Williams] does a great job as far as executing the defense called,” Gase said. “He’s going to play with a lot of energy, I don’t think there’s going to be any doubt about that. Just watching him practice, watching him go through the preseason, I’m sure he’ll be excited. It’s a different feeling that first week of the season. When you’re a rookie, you don’t know until the game hits, but the speed is amplified times 100.”
