Jets fans have been clamoring for one fourth-round rookie to get his shot.

Another is already making the most of his.

While quarterback Cade Klubnik waits behind Geno Smith, defensive tackle Darrell Jackson Jr. is coming off his best game of the season. He finished with four tackles, a sack, a tackle for loss and a quarterback hit in the Jets’ 17-12 victory over the Browns.

“Just being around the guys, the older guys, the vets,” Jackson said. “Just going in the office talking to Coach [Karl] Dunbar and talking over what he expects from me and what I expect for myself.

“Just coming into that mentality that I can go out there and do it. Just going out there and putting it on display, I feel like it has been big.”

Rookie edge rusher David Bailey earned AFC Defensive Player of the Week honors after recording three sacks against Cleveland. But Jackson also gave the Jets a glimpse of what he could become.

“We give David a lot of flowers, but D-Jack has been working his tail off since he got here,” Jets defensive tackle Jowon Briggs said. “It was nice to see a big guy, good guy going out there, especially in the D-Tackle room getting production like that.

“Two passes deflected back-to-back and big-time moments getting that sack. I would say it’s a long time coming, but I’m not surprised. And I expect him to have more performances like that because he’s one heck of a player.”

Before the Jets selected him 103rd overall in April’s draft, Jackson took a winding path through college football. He began his career at Maryland before transferring to Miami and later Florida State. After redshirting in 2023, he started 25 games for the Seminoles, totaling 80 tackles, 4.5 sacks, and 7.5 tackles for loss. He earned All-ACC honorable mention in each of his final two seasons.

Jackson entered the NFL projected as a run-stuffing rotational player in Aaron Glenn’s defense. But veteran defensive tackle David Onyemata’s move to injured reserve following core muscle surgery gave the rookie his opportunity.

In his first four games, Jackson has recorded eight tackles, a tackle for loss and a quarterback hit. Against Cleveland, he showed he could do more than clog rushing lanes.

Jackson helped pressure Deshaun Watson as the Jets piled up eight sacks, adding interior pressure to complement Bailey and the rest of the pass rush.

“He’s another guy that has been getting a ton of reps, and the thing is, he’s deserved those reps, because he has been playing his butt off,” Glenn said. “When you look at a guy of his stature, he really fits exactly what we’re trying to do as far as that five technique and then being able to reduce down to a three technique, and sometimes even a shade for us.

“Each week he’s getting better. He’s getting better, and he’s understanding exactly what we do and how we’re trying to do it, so kudos to him and kudos to Dunbar for pushing him to where there’s no stopping to what he’s trying to do, and you have to earn everything you get, so he’s been doing a good job of that.”

Jackson also used his 6-5 frame and 7-2 wingspan to disrupt passing lanes, batting down those consecutive throws at the line of scrimmage. With Onyemata’s return timetable unknown, Jackson has a chance to stake a claim to a bigger role.

The Jets wanted more size and versatility along their defensive front. Jackson offers both, combining strength and length at the point of attack with surprising quickness for a 315-pound player. Those traits complement fellow defensive tackles Briggs, Harrison Phillips and T’Vondre Sweat.

Film work and guidance from the Jets’ veterans have helped Jackson grow more comfortable. The next step is turning his breakthrough against Cleveland into a weekly expectation.

Klubnik may remain the fourth-round pick fans want to see. Jackson is becoming the one opposing offenses have to account for.

“The game has slowed down for me,” Jackson said. “When you first get out there, everything is moving fast, so you feel like everything is different.

“But when you get back to the basics, it is just football. Just go out there and be prepared and just go out there and hit somebody.”
