The 2026 NFL season is here, and while NFL Mocks will have you covered on the road to the 2027 NFL Draft, we'll also be keeping a close eye on the 2026 draft class to see which rookies emerge as immediate stars.
After projecting our All-Rookie offense, it's time to turn to the defensive side of the ball and highlight the players we believe will have the best rookie seasons in 2026.
The 2026 class was filled with so many interesting debates regarding positional value and hybrid players, but now it's about how the players play on the field. Building out these all-rookie teams brings us back to a lot of questions about "value" or "impact", whether it be based on counting stats or the quality of snaps played.
Does the edge rusher with more sacks get the nod over the one who plays more snaps and defends the run better? Does the linebacker with more tackles beat out the one who makes a bigger impact in coverage? And does the cornerback with more interceptions get the edge over the one quarterbacks simply stop targeting?
Those are the debates we'll be watching all season. For now, here are our predictions for the 2026 NFL All-Rookie defense.
Projecting the 2026 NFL All-Rookie defense
EDGE: Rueben Bain Jr, Tampa Bay Buccaneers
When the Tampa Bay Buccaneers selected Rueben Bain, he became the skeleton key of the 2026 class. But not just for the Bucs.
Bain was in the top five of big boards all season, and falling to the Bucs at No. 15 as a perfect fit for a Todd Bowles defense feels like something we'll all look back on and say, "I can't believe the league let him fall there."
Bain is going to be on the field right away because of his strength as a run defender and edge setter. Even though he is undersized, his squatty body gives him natural leverage to hold his ground.
The run defense gets him on the field, but the pass-rush ability will keep him there and give him the production. He's a natural bull rusher who uses his strong hands really well, with a punch/swipe to shock blockers, as well as a swim move to get by. Within this well-built defense, Bain should have a big year.
Projected Stats: 800 snaps, 52 combined tackles, 7.5 sacks, 2 forced fumbles, 1 fumble recovery
EDGE: David Bailey, New York Jets
David Bailey is a natural pass rusher with all of the traits you could want. He has a compact but thick frame, which will give him good leverage and the ability to move past blockers, as well as elite burst off the edge.
The Jets remade their defensive roster this offseason, but no significant moves at edge rusher that will get in the way of Bailey. In fact, they cleared the way for him by trading away Jermaine Johnson II.
It is unlikely the Jets ask Bailey to do anything he can't do, which means he'll get plenty of opportunities to pin his ears back and rush after the quarterback. Bailey should lead the rookie class in sacks in 2026.
Projected Stats: 700 snaps, 45 combined tackles, 10 sacks, 1 fumble recovery
DT: Peter Woods, Kansas City Chiefs
The Kansas City Chiefs are counting on Peter Woods a lot this year. On their path to getting back to the Super Bowl, they revamped the defense during the offseason, and Woods serves two key purposes in doing so.
Through the prime years of Chris Jones, the Chiefs have opted for a run-defending nose tackle-type to play next to him. But now that Jones is 32-years-old and coming off of back-to-back single-digit sack seasons, they gave him a real running mate instead.
At Clemson, Woods showed flashes of being an interior penetrator as a big defensive tackle with a quick first step. The playing weight he's reportedly at this year should give him the best of his strength and quickness in order to do just that.
The combination of his own sacks, plus the pass-rush lanes he helps open up for Jones, will make for a great season for Woods.
Projected Stats: 500 snaps, 38 combined tackles, 3 sacks, 1 fumble recovery
DT: Kayden McDonald, Houston Texans
The Houston Texans have built an elite defense since DeMeco Ryans became the head coach. But the one position they hadn't yet fully addressed was the defensive tackle. Veterans Tim Settle and Sheldon Rankins have manned the position the most in the last three seasons, and played well enough, but neither reached the heights of the rest of the unit.
In comes Kayden McDonald. The perfect fit for what Ryans and the Texans needed. McDonald has a chance to be an elite run defender with his size, length, and physicality. But he's not just a plugger. McDonald uses a quick first step and long arms to knife into the backfield when asked to make plays behind the line of scrimmage.
Conditioning and overall foot speed might keep McDonald from being a true pass rusher, at least as a rookie. But as the final piece of this already great defense, McDonald will plug a lot of holes. Literally and metaphorically.
Projected Stats: 400 snaps, 30 combined tackles, 1 sack, 1 forced fumble
Which rookie linebackers will make an immediate impact?
LB: Sonny Styles, Washington Commanders
2026 was the year of the linebacker in the draft, with seven being drafted in the first two rounds. That number had been two or three in years past. In 2026, we had two drafted in the top seven picks.
All that said, the linebackers should have productive seasons, even as rookies, in 2026. Sonny Styles, in particular, is getting a big role in the Washington Commanders' defense this year. He'll be on the field most of the time and even wear the green dot in certain packages.
Styles's blend of size, instincts, and athleticism will lead to plenty of production on the field. Whether that be tackles, sacks, or turnovers. But his IQ will also help him play sound football in the middle of Washington's defense, which is something they'll need from him this year.
Projected Stats: 900 snaps, 130 combined tackles, 3 sacks, 1 interception, 1 forced fumble
LB: Arvell Reese, New York Giants
Arvell Reese is the other highly drafted linebacker from the 2026 class. He doesn't have the same coverage experience as Styles, but his instincts and hitting ability are off the charts.
Reese will also be on the field plenty, but he has the benefit of playing next to a veteran in Tremaine Edmunds. Playing next to Edmunds will allow Reese to go full speed and make plays.
Reese will be used in a multitude of ways, allowing him to impact different aspects of the game. He'll rush off the edge, blitz through the interior of the line, and probably drop out into coverage. And he has the talent to do all of those things well.
Projected Stats: 930 snaps, 90 combined tackles, 4 sacks, 2 forced fumbles, 1 fumble recovery
Projecting the 2026 NFL All-Rookie secondary
CB: Mansoor Delane, Kansas City Chiefs
As we mentioned, the Chiefs have overhauled their defensive roster. But while Woods gets to play with Jones, George Karlaftis, and Nick Bolton up front, Mansoor Delane is being counted on for a lot in the secondary as the team's starting outside corner.
But Delane is up for the challenge. He has the requisite size and athleticism needed, but his instincts and IQ are what helped him stand apart in the 2026 class. Like Bain and Bowles, there's a real chance Delane and Steve Spagnuolo have a mind-meld during Delane's rookie season.
Delane will have his struggles as all rookies do, especially at cornerback, but Spagnuolo is known for putting his secondary in good positions, even early in their careers. And Delane has all of the tools to capitlize on that opportunity.
Projected Stats: 900 snaps, 55 combined tackles, 3 interceptions
CB: Avieon Terrell, Atlanta Falcons
There are other cornerbacks slated to have bigger roles than Avieon Terrell in week one. But the buzz around Terrell this summer, plus his draft profile, tell us it's only a matter of time until he's on the field making an impact.
Terrell has been taking reps this summer on the outside and in the slot for the Falcons. As an outside corner, his speed and ability to mirror receivers stand out. And while he wasn't much of a slot player in college, his quickness and physicality tell us he'd also thrive in that role.
Having a few weeks to start the season in a fairly talented secondary will only help Terrell over the long run of the NFL season. And once he's on the field, he'll be ready to make a significant impact.
Projected Stats: 700 snaps, 70 combined tackles, 1 interception, 1 forced fumble, 1 fumble recovery
NB: Caleb Downs, Dallas Cowboys
With the significance of the nickel corner in today's NFL, we had to specifically designate Caleb Downs as a nickelback for this team. New defensive coordinator Christian Parker is coming over from the Philadelphia Eagles, where this role is filled by Cooper DeJean.
Downs is an extremely instinctual and high-IQ player. Getting him as close to the line of scrimmage gives him and the Cowboys the highest chance of success in 2026. He is excellent at diagnosing a play and making a tackle on the ball in the middle of the field.
But having him at cornerback also allows him to impact the game in coverage. And while he doesn't have elite coverage chops in terms of reps or physical traits, he has just enough of those to let his football acumen take him to the necessary level.
Downs can be the linchpin of the Cowboys' defense trying to course-correct under Parker.
Projected Stats: 950 snaps, 80 combined tackles, 2 sacks, 2 interceptions, 2 forced fumbles, 1 fumble recovery
S: Treydan Stukes, Las Vegas Raiders
Treydan Stukes is a versatile defensive back with good size and speed. He made himself known very early in training camp and overtook Isaiah Pola-Mao for one of the starting safety spots.
Stukes will be moved around in the Raiders' defense, giving him plenty of chances to produce. He'll likely have a lot of tackles and be involved in multiple turnovers.
The Raiders are undergoing enough changes defensively that Stukes will have plenty of opportunity to find his role in the defense and hold on to it. But there's still enough talent on the roster in Maxx Crosby, Eric Stokes, and Jeremy Chinn that Stukes is insulated just enough to help him shine.
Projected Stats: 1,000 snaps, 90 combined tackles, 2 interceptions
S: AJ Haulcy, Indianapolis Colts
Like Stukes, AJ Haulcy quickly moved into a starting role for the Colts in training camp. Haulcy's physicality helps him stand out on the field and will give the Colts a bit of an edge they need from the group.
Haulcy can play as a deep or centerfield safety if asked, but his best trait is playing downhill in the box. Teammate Cam Bynum at the other safety spot perfectly complements Haulcy, which will allow the rookie to focus on what he does well.
Haulcy should still see a role in pass coverage, though. He has the athleticism and instincts, but he plays flat-footed in coverage, so he can be late to the ball. But with an experienced and skilled defensive coordinator in Lou Anarumo, Haulcy should develop and be put in position to succeed right away.
Projected Stats: 1,100 snaps, 95 combined tackles, 1 sack, 1 interception
This is our starting point for the 2026 rookie class on defense, but we know there will be plenty of surprises along the way. Now it's time to see which rookies step up, make an impact, and force their way onto the All-Rookie Team by the end of the season.
