10 Rookies From the 2026 NFL Draft That Are Already Showing Major Green Flags

The 2026 NFL season is rapidly approaching, as we have to get through the preseason and see rookies get evaluated and make their marks in front of the world.

Some of these guys may have a couple of red flags, but the green flags outweigh the red and should cause some excitement for the fan bases of teams looking to rebound for a stronger 2026 season. 

These rookies bring a lot of promise to their respective teams and could be the missing pieces they need to make a run towards the playoffs.

Which players in the 2026 NFL Draft are showing a ton of promise?

Caleb Downs

Drafted 11th overall by the Dallas Cowboys, Downs is already drawing rave reviews for his plug-and-play versatility and will likely have a huge impact on the Cowboys’ secondary once the regular season begins.

Head coach Brian Schottenheimer revealed that Downs is one of four defenders and the only rookie trusted to wear the green-dot helmet during training camp, as the green dot designates players listening in to defensive play calls from the sidelines and communicates them to teammates on the field.

Downs is incredibly versatile, as mentioned earlier, and can be utilized in multiple spots in the defensive formation, making him a great safety to coach under defensive coordinator Christian Parker.

Oh, and Downs can play different roles like a nickel-corner close to the line of scrimmage, inside the box, and a deep-middle third safety role.

Downs is also incredibly fearless against the opposing competition, as he’s battled CeeDee Lamb in 11-on-11 drills during training camp and held his own.

Downs looks to see numerous interceptions and fumble recoveries when the regular season begins. Don’t be surprised if the Cowboys make a playoff run because of Downs boosting the team’s defense. 

Rueben Bain Jr.

Although Bain Jr. has had his off-field issues, he brings a high football IQ to the Buccaneers’ defense and immediate backfield disruption by collapsing the pocket very quickly.

Bain Jr. has dominated early trench work, positioning himself as a potential NFL Defensive Rookie of the Year candidate in 2026, thanks to the explosive plays he’s shown in training camp so far.

Besides disrupting opposing quarterbacks, Bain Jr. is incredibly versatile by dropping into coverage and making game-changing tackles against elite offensive talent.

Bain Jr. displays a no-nonsense, elite mentality with his strict business demeanor, focusing on practice instead of rookie distractions.

Bain Jr. also plays with a chip on his shoulder, as critics have pointed out how his arm length may not be suitable against the league’s best offensive linemen.

When the regular season begins, we look forward to seeing Bain Jr. dominate in Todd Bowles’ defensive system and the havoc he will cause against opposing offenses getting in his way. 

Vega Ioane

Ioane has so far been a standout for the Ravens during OTAs and training camp, as he looks fully prepared to take on a day-one starting role.

Ioane has looked like a polished veteran rather than a rookie out of college, thanks to his maturity and business-first mentality, adapting to the Ravens’ physical identity.

Head coach Jesse Minter and general manager Eric DeCosta have raved about Ioane’s physical tools and referred to him as a “beast” during early offseason practices, watching him transition from college to a pass-blocker ready for the professional level.

Video clips from OTAs have shown Ioane exploding right off the snap and effortlessly moving opposing defenders, which is a great sign for the Ravens’ offensive line heading into the regular season.

Ioane’s rare combination of power and mobility fits the Ravens’ run-heavy scheme, as he’ll protect Lamar Jackson and Derrick Henry from disruptions by opposing defenses.

Ioane also brings great leadership traits, having already established himself as a tone-setter in the locker room, excellent communication skills, and reinforcing the narrative that he’s ready to anchor the interior offensive line for years to come. 

Sonny Styles

Washington Commanders rookie linebacker Sonny Styles has generated immense excitement and has flashed significant green flags heading into the 2026 season.

Styles has been trusted to wear the green dot on his helmet, as defensive coaches will feed him play calls while in traffic and lead Dan Quinn’s defense on the field. 

Defensive coordinator Daronte Jones has said that the game isn’t too fast for Styles and he’s reacting rather than overthinking. 

Fellow linebacker Leo Chenal has praised Styles’ maturity and referred to him as a guy who’s more like an eight-year veteran than a rookie.

Styles has played linebacker and safety back in his college days at Ohio State, and that versatility is a huge asset for the Commanders heading into the 2026 NFL season. 

His ability to absorb complex defensive concepts allows coaches to move him seamlessly, making him a Swiss Army knife and building excellent defensive schemes around him.

Styles also has strong maturity and a purposeful mindset and has embraced the pressure of becoming a starter on day one. 

Arvell Reese

Staying in the NFC East, Arvell Reese is showing significant green flags for the Giants by demonstrating elite coverage versatility, physical traits, and a sharp mental approach to the game. 

Reese has displayed stellar pass coverage by tracking down opposing wide receivers like Odell Beckham Jr. in practice to break up passes from Jaxson Dart.

At six-foot-four, Reese’s 32.5-inch arms and wingspan have caused disruptions against opposing offenses, which has earned praise from head coach John Harbaugh for how Reese can bat down balls that other linebackers can’t.

Reese’s development has been stark, as he’s a “see ball, get ball” kind of guy who’ll cause an immediate impact against opposing offenses when the regular season begins. 

Defensive coordinator Dennard Wilson is actively exploiting Reese’s college edge-rushing traits, and the team has successfully lined him as an off-ball linebacker, a stand-up blitzer, and a true edge rusher. 

Reese also has an elite execution to his style of play in the first-team run-defense sessions during training camp, and he’s shown no hesitation plugging gaps and hitting his assignments cleanly.

Carnell Tate

Titans’ rookie wide receiver Carnell Tate has shown excellent green flags during the 2026 NFL offseason workouts and training camp.

Tate has traveled to Houston during breaks to build a strong chemistry with second-year quarterback Cam Ward, which is very important for when the regular season begins.

During training camp, Tate has shown effective red-zone efficiency on multiple touchdown passes from Ward, signaling immediate comfort in tight spaces. 

Tate has shown elite route-running, which allows him to adjust to complex NFL schemes, and an excellent catch radius, with spectacular one-handed grabs during practices. 

Tate has also been competing to earn the Titans’ WR1 role against veterans like Calvin Ridley and Wan’Dale Robinson, and is looking like he’ll become that X factor for the team.

During OTAs, Tate caught 10 passes and scored three touchdowns during two open media sessions, which drew rave reviews from NFL veterans.

Tate should be ready for regular-season action and will form great on-field chemistry with Cam Ward during key games when week one kicks off. 

Fernando Mendoza

Even though Kirk Cousins was named the Raiders’ starting quarterback heading into the 2026 season, Mendoza has shown some positive green flags fans of the “Silver and Black” should enjoy. 

Mendoza embraces a learning mindset, as he’s focused on competing “with” rather than “against” Cousins.

Following early practices, Mendoza has acknowledged he has a learning curve, but he has shown a high level of self-awareness. 

Team reporters have noted that Mendoza doesn’t have an ego and is completely down-to-earth, has an authentic demeanor, and has quickly earned respect from his peers in the locker room.

Offensive Coordinator Andrew Janocko has praised Mendoza for instantly absorbing information as it comes from meetings and applying it on the field in real time. Not to mention, observers have seen how fast Mendoza can get the ball out of his hands, limiting negative plays.

Mendoza has an incredible work ethic, as he’s taken 25-50 extra snaps under center at his hotel every night just to build muscle memory and tackle his weaknesses by moving away from the shotgun-heavy college systems to an under-center professional system.

Mendoza has also shown he’s capable of being a dual-threat runner by breaking away from defenders by flashing mobility for certain gains during scramble drills.

When Mendoza eventually starts for the Raiders, he will bring much-needed excitement to a team wanting a true game-changing quarterback. 

Cyrus Allen

Kansas City Chiefs rookie Cyrus Allen has emerged as a breakout star in early training camp, flashing several major green flags that “Chiefs Kingdom” will like to see during the regular season.

Allen is quickly emerging as one of Patrick Mahomes’ new favorite targets, as he’s repeatedly looked for him during 11-on-11 drills and has thrown passes for Allen even when coverage is incredibly tight. Head coach Andy Reid has praised the growing chemistry between Mahomes and Allen, saying, “I think Pat’s got some trust there.”

Just like Carnell Tate, Allen has also made some viral one-handed catches over multiple defenders, adding to the excitement when the regular season kicks off. 

Not to mention, Allen has already outpaced fellow veteran wide receivers during first-team reps and hauled in five passes during day three of training camp, which was the most of any receiver in the 11-on-11 drill.

Xavier Worthy has praised Allen as an electric route runner, which is something the Chiefs truly need heading into the regular season.

Allen has also adjusted fairly quickly to Andy Reid’s notoriously complex playbook, when rookie receivers had struggled with it in the past. When week one kicks off, Allen should hit the ground running and fit in beautifully to Reid’s and offensive coordinator Eric Bieniemy’s system.

Mansoor Delane

Staying on the Chiefs, Mansoor Delane has also shown exciting green flags on the defensive side of the ball. 

Delane has capitalized on mistakes by reading deflections yards away in zone coverage and has intercepted passes in practice that were meant for Travis Kelce. 

Head coach Andy Reid has praised Delane’s maturity and strong work ethic, calling him smart, focused, sharp, and willing to work, making for a great addition to the Chiefs’ rebuilding secondary.

Despite dealing with a shoulder injury and wearing a non-contact yellow jersey during OTAs, Delane has stayed mentally locked in and took as many active, non-contact snaps as he could. 

Delane has openly acknowledged that it can be naturally hard for him to turn down his signature on-field aggression; he does recognize he needs to play smart and protect his teammates during training camp. 

Delane has told reporters he’s chasing perfection and isn’t just trying to survive training camp, but rather master it, making him the perfect guy for defensive coordinator Steve Spagnuolo’s system. 

Delane has also been rapidly adapting to Spagnuolo’s heavy-man coverage scheme, drawing on his extensive press and vertical phasing experience from his collegiate days at Virginia Tech and LSU.

When training camp and the preseason are all said and done, the Chiefs may have a new Pro Bowl-caliber cornerback causing havoc against the NFL’s best wide receivers for the 2026 regular season.

David Bailey

Rookie edge rusher David Bailey has flashed significant green flags that should excite Jets fans during training camp ahead of the 2026 regular season.

Bailey has shown he’s a sack producer by getting three would-be sacks during day two of training camp in unpadded drills. 

Bailey is a natural bull-rusher who can split tackles and break double teams to get to opposing quarterbacks, as his signature burst and sudden change of direction have left opposing tackles off balance.

His football IQ has shown in training camp, as he focuses on misdirection plays and maintaining edge containment against the run rather than hunting sacks. 

Not to mention, Bailey has told reporters he doesn’t let his draft position get to him, and there’s no added pressure even when playing in a stressful New York sports market.

Teammates and coaches have raved about Bailey’s high motor skills and daily work ethic, as he approaches every workout and practice with a veteran’s mindset. 

Starting center Joe Tippmann has also given Bailey the ultimate compliment by referring to him as the ultimate pain in the butt to block. 

When the regular season begins, Bailey will stand out as a pass-rushing machine in head coach Aaron Glenn’s and defensive coordinator Brian Duker’s system, and we can’t wait to see it all unfold.
