Master scouting report

Duff is a towering outside receiver whose catch radius, body control and contested-catch production can change the geometry of a passing game. He must prove that his releases, route pacing and speed create enough clean targets against NFL press coverage instead of forcing every win through contact.

By Draftanomics · Sources & edition · Print report

01Career And Production

Duff started all 12 games for Rutgers in 2025 and led the team with 60 catches, 1,084 yards and seven touchdowns. He averaged 18.1 yards per reception, produced a 241-yard game at Purdue and earned second-team All-Big Ten honors.

02Size And Catch Radius

Rutgers lists Duff at 6-foot-6 and 225 pounds, giving quarterbacks an unusually large target outside the numbers. He extends naturally beyond his frame and can shield the ball from smaller corners. That size is a true receiving advantage, not a reason to relabel him as a tight end; his 2026 role remains wide receiver.

03Contested Catch Skill

He tracks the ball through contact, positions his body between the defender and the throw and finishes with strong hands away from his chest. The skill can rescue difficult placements, but an NFL offense will still want more separation before asking him to live on low-percentage chances.

04Releases And Press

Duff can use length and play strength to clear a corner's hands, and his stride eats space once he is free. He needs a more varied package of footwork, swipes and pace changes to prevent physical corners from dictating the rep.

05Route Running

His route work is more developed than a simple jump-ball label suggests. Tighter cuts and greater urgency at the top of short routes would create easier throws underneath.

06Vertical Game

Duff produced 21 receptions of at least 20 yards in 2025, showing that the long stride and catch-point control generate explosive plays. He can stack a corner after gaining outside leverage and remains available when the defender recovers. Pure speed is not the foundation of his game, so safeties with good angles can cap routes that depend only on running past coverage.

07Hands And Ball Tracking

Strong, confident hands allow Duff to pluck throws above his helmet or outside his frame. He adjusts late without losing position and remains composed near the sideline. His reliability gives a quarterback freedom to place the ball away from leverage rather than aiming for a perfect strike.

08After The Catch

Duff is a build-up runner who can stride through open grass and use his frame to finish forward. His NFL value will come from catches downfield and possession wins more than a screen-heavy workload.

09Blocking And Physicality

The frame gives Duff the tools to block corners and crack smaller defenders when his hands land inside. More consistent pad level and sustain would make him an asset on early downs rather than merely an imposing matchup receiver.

10Role And Development

Duff enters 2026 with preseason All-America recognition and a place on the Senior Bowl Top 300. He has already shown he can command volume when every defense knows where the ball is going. The final step is proving that sophisticated press and safety help cannot reduce him to a specialist who needs contested throws to stay involved.

The case for the player

Strengths

  • An enormous catch radius expands the available throwing window.

  • He produced 1,084 yards and seven touchdowns as a first-year full-time starter.

  • Body control and tracking remain effective through contact and near the sideline.

  • Twenty-one catches of at least 20 yards demonstrate real downfield value.

  • His long stride creates late separation on vertical and crossing routes.

The questions that remain

Concerns

  • Quick press corners can delay his release before the long stride opens.

  • Short-area separation is less consistent than his work downfield.

  • He offers modest elusiveness and tackle-breaking value after the catch.

  • Average top speed allows well-positioned safeties to cap purely vertical routes.

Building the fit

NFL role and scheme fit

Use Duff as a boundary X who can dictate isolated coverage, win back-shoulder throws and attack the red zone. Posts, fades, deep overs and comebacks let him use his stride and catch radius, while reduced splits or motion can prevent corners from landing an uncontested jam. He can move into the slot against smaller defenders, but his greatest value comes from forcing a defense to decide whether one corner can handle him outside. He profiles as a starting possession receiver with explosive-play value if the release package keeps improving.

The Draftanomics view

Bottom line

Grant Potter's full report reaches the right tension: elite catch radius and reliable hands against limited short-area quickness, separation and yards after the catch. The 1,084-yard breakout proves he can carry targets, not that every NFL target will remain available when corners crowd the release. Duff belongs in the second-day conversation; a first-round rise requires clean wins against press rather than more spectacular catches through coverage.
