Boom or bust: Who are 2026 NFL Draft's high-risk, high-reward prospects?

It didn't take long for one of the most volatile prospects in the 2025 NFL Draft to find his way as a pro.

In compiling one of the most remarkable testing profiles in recent history at the NFL scouting combine, South Carolina safety Nick Emmanwori carved out a space for himself as one of the draft's most dynamic defensive players. Yet his urgency and recognition didn't always align with his timed speed, and he had to wait until the second round to be selected by the Seattle Seahawks. In coach Mike Macdonald's defense, however, Emmanwori blossomed in a bespoke role that allowed him to harness his athleticism and playmaking streak. He became more formidable as the season progressed for the eventual Super Bowl champs and finished as runner-up in NFL Defensive Rookie of the Year voting.

Is there a lesson there for the rest of the league in how to approach high-risk, high-reward prospects in this year's draft?

Trying to account for the gap between a player's proven play and their capabilities can be one of the more bewildering elements of evaluations. While placing a premium on unrealized potential can lead to success stories like Emmanwori's, not all draftees or teams are equipped to reach that ceiling - or even approach it. In this year's class, several figures present a difficult dilemma, with wildly disparate outcomes on the table for their development.

Here are the 10 biggest boom-or-bust prospects in the 2026 NFL Draft:

QB Taylen Green, Arkansas

In most cases, a player who might not be selected until Day 3 wouldn't warrant mention in this exercise. Green, however, is a singular case. At 6-6 and 227 pounds with breakaway speed (4.36 seconds in the 40-yard dash) and dazzling arm strength, he has unmatched big-play prowess behind center.

Yet despite his distinct set of physical gifts, Green has remained resolute that he won't entertain a position switch. That could limit his options considerably in the early stages of his career, as teams will be reticent to trust a quarterback who is consistently late and reckless when operating from the pocket. As a developmental option, he's uniquely alluring. Without making significant strides, however, Green will have a difficult time sticking even as a backup.

WR Zachariah Branch, Georgia

Even by Southeastern Conference standards, Branch is on a different level from his peers when it comes to speed. He blazed a 4.35-second 40-yard dash at the combine, and pulling away from would-be tacklers in the pass and return game was little problem for him.

As a receiver, however, Branch has an extremely limited comfort zone that might not easily be expanded. By spamming the 5-9, 177-pounder with screens and throws at or behind the line of scrimmage, Georgia reduced him to a gadget player and inhibited his development. Branch can gain more comfort tracking deep balls, but his minimal catch radius doesn't bode well for downfield work. While his value on special teams provides a floor, Branch embodies a receiver archetype - undersized slot who depends on generating big plays out of schemed touches - with a rather uninspiring hit rate.

WR Chris Brazzell II, Tennessee

In his sizzling September start, the Tulane transfer differentiated himself at least slightly from recent Tennessee receivers. While several of his predecessors revealed themselves as one-note deep threats propped up by the Volunteers' rudimentary passing attack, Brazzell showed a level of fluidity that should enable him to diversify his route tree. Still, the primary selling point is how the 6-4, 198-pound target can stretch defenses vertically.

Yet press coverage seems bound to disrupt him, and Brazzell will be subjected to those looks until he proves he can punish cornerbacks who try to get physical with him. That concern isn't just limited to his work at the line of scrimmage, either. Brazzell is accustomed to simply plucking the ball over the heads of defenders, but fighting for tight-window throws won't come easily to a player who's not particularly comfortable operating in close quarters. With the play strength problem also percolating in the quick game and in his lack of contributions after the catch, Brazzell might be boxed into a limited role until he proves himself more trustworthy over the first two levels.

TE Kenyon Sadiq, Oregon

At a time when many NFL teams are changing the personnel calculus for opposing defenses by routinely utilizing two or three tight ends, Sadiq arrives as a uniquely challenging matchup. The 6-3, 245-pounder ripped off a 4.39-second 40-yard dash at the combine, reinforcing just how dangerous he can be in breaking free from coverage anywhere on the field. Sadiq also is tenacious as a run blocker, doling out big hits to unsuspecting defenders in space.

His production in his one year as a starter, however, was not that of a truly dominant weapon in the passing game, with drops an all-too-common problem. Much of that falls on Oregon's offense, but Sadiq lacks the track record as a seam threat that would provide greater assurance about his projection. And for as determined as Sadiq tends to be as a blocker, he can be overwhelmed when left to ward off defensive ends rather than linebackers or safeties. His future offensive coordinator should be able to create mismatches with Sadiq and free him up for run-after-catch opportunities, but there's still work to be done if he's to fully deliver on his immense potential.

TE Eli Stowers, Vanderbilt

A converted quarterback, Stowers took to his new position right away, winning the John Mackey Award in just his third year as a pass catcher. Still, the New Mexico State transfer is hardly tapped out on growth. With his 4.51-second speed in the 40-yard dash and 45 1/2-inch vertical leap, Stowers can create mismatches down the seam far more often than he did for an aerial attack that seldom sought to weaponize him in that way.

As essentially a supersized slot, however, Stowers relies on either being schemed into open space or creating it for himself, as he has yet to demonstrate he can consistently pull down catches in traffic. He's also very nearly a non-factor as a blocker, which eliminates any possibility of him being used as an in-line option. That means Stowers will have to earn his keep on his production as a detached receiver, and his production there might not be quick to materialize.

OT Kadyn Proctor, Alabama

At 6-7 and 352 pounds, Proctor has operated outside the norms for a left tackle since he became a Day 1 starter for the Crimson Tide. When he's dialed in, he can shut down paths to the quarterback for even the speediest edge rushers. And driving defenders backward on run plays comes easily to him.

Proctor's build, however, can't save him from several notable shortcomings. His eagerness to envelop edge rushers leaves him vulnerable to inside moves, and he's too easily thrown off balance. After exceeding 400 pounds as a freshman, Proctor will face heavy scrutiny for his playing weight. For now, though, lapses in technique are the bigger threat to Proctor finding any sense of reliability as a blocker.

DT Caleb Banks, Florida

At his best, Banks has all the trappings of a top-10 pick. No defensive tackle is more difficult to handle right off the snap than the 6-6, 327-pounder, who's equally comfortable pushing back blockers and shooting gaps. Highlights, however, hardly tell the full story.

Banks missed all but three games of last season due to a foot injury, and he was sidelined again at the NFL scouting combine with a fracture of his fourth metatarsal. That track record alone could be cause for concern, and it's compounded by the more undeveloped elements of his game. Banks' quickness and forcefulness off the line of scrimmage is too often mitigated by his leverage issues and improper hand usage. And despite his knack for making his way into the backfield, he's developed lots of bad habits as a tackler, too often allowing quarterbacks and ball carriers to escape his clutch. With a more disciplined approach, Banks could become one of the most formidable interior forces in the league. Until then, he might only generate sporadic disruption.

OLB Cashius Howell, Texas A&M

When in pursuit of a quarterback, Howell has a way of keeping others' hands off of him. The Bowling Green transfer racked up 11 1/2 sacks and became the SEC Defensive Player of the Year by rocketing past blockers off the snap and flattening his rush. Yet he doesn't merely rely on straight-line speed, as he can rapidly redirect and knife back inside when needed.

When a lineman does make contact with Howell, however, he has limited recourse. The 6-3, 253-pound edge rusher can be washed out of run plays, and his 30 1/4-inch arms - well below the universal threshold at the position - make disengaging tricky. He should provide his fair share of splash plays, but Howell might find an every-down role hard to come by until he becomes a stouter and more reliable presence.

CB Brandon Cisse, South Carolina

In short bursts last season, Cisse looked capable of following Mansoor Delane and Jermod McCoy to become the third cornerback selected in this year's draft. At just shy of 6-0 and 189 pounds, he looks built to stay glued to bigger targets downfield. But the North Carolina State transfer still depends on his athletic tools to do the heavy lifting in college, and they might need to do the same for his draft stock.

Though his instantaneous closing speed makes him a dangerous player to test in college, Cisse too often doesn't get a bead on throws to his area until it's too late. With just 10 passes defensed and two interceptions across his college career, his sense for making a play on the ball remains underdeveloped. The bigger worry for his pro projection, however, is how easily he can be outmaneuvered by receivers who don't merely operate in a straight line. He could be a volatile presence in the early going, with repeated chunk gains given up if left to operate in zone or off coverage too frequently. Still, teams might be understandably eager to mold a corner who can handle some of the most imposing coverage assignments a defense can face.

S Jalon Kilgore, South Carolina

The Emmanwori comparisons are inevitable for the player who followed the standout safety at South Carolina. At 6-1 and 210 pounds with the ability to cover plenty of ground, Kilgore has not just the physical makeup of a multitalented playmaker, but also the disposition of one.

But expecting anyone to follow the same trajectory of a player on his own athletic plane inevitably will end in disappointment. For Kilgore, any parallels to his former teammate might start to fall apart when discussing their pro roles. While Emmanwori flourished as a do-everything nickel for the Seahawks, Kilgore is prone to being shaken by quick-twitch slot receivers at the underneath and immediate levels. Handling tight ends and patrolling from deep might better suit his skill set, but that vantage point is a largely unfamiliar one for Kilgore. With his inconsistencies extending to his run fits and tackling, Kilgore might test the patience of whatever team drafts him.
