Derrick Harmon: The Catalytic Force On The Defensive Line
Derrick Harmon, the Steelers’ first-round defensive tackle selection in 2025, is rapidly becoming one of the most talked-about rookies this NFL winter. Towering at 6’6” and over 320 pounds, Harmon’s size alone catches your attention. Yet, his most remarkable trait isn’t just his imposing frame—it’s the surprising agility and explosiveness he brings to the trenches.
During the Steelers’ rookie minicamp, coaches and teammates described Harmon as a rare blend of size, strength, and fluid athleticism. Unlike many big men who plod through drills, Harmon carries his weight with a grace that allows him to maneuver around blockers, generate bursts of speed, and execute complex pass-rush moves with precision. Defensive line coach Karl Dunbar was visibly impressed when teammate Yahya Black’s drill efforts literally pushed him backward, underscoring the type of power embedded in the rookie squad.
Harmon’s pressure statistics from college hint at his disruptive upside—he led the NCAA with 55 pressures, a number that caught the eye of talent evaluators nationwide. The rookie’s ability to attack the pocket with a mix of raw power and nuanced moves already compares favorably to established NFL talents.
- Height & Weight: 6’6”, 322 lbs
- College Production: NCAA leader in pressures (55)
- Draft Round: 1st Round, 2025 NFL Draft
- Projected Role: Key rotational player, especially on third downs
- Strengths: Explosiveness, versatility, pass-rush variety
Despite the rookie season’s inevitable learning curve, the Steelers’ plan appears to be gradually integrating Harmon into their defensive front alongside veterans like Cam Heyward and Keeanu Benton. Historically cautious about overexposing young defensive linemen, Pittsburgh is balancing his development while maximizing his bursts of game-changing potential.
| Metric | Value | Notes |
|---|---|---|
| Age | 21 | Standard age for rookie DL |
| 40-yard Dash | 4.95s | Top 25% for DLs, showing speed |
| Weight | 322 lbs | High-level NFL size |
| Height | 6’6” | Elite height in position |
| Pressure Count (College) | 55 | Led NCAA in pressures |
Harmon’s presence impacts not only the defense’s power but the psychological edge. The combination of his build and movement suggests he can be a game-changer in short-yardage and pass-rush situations. Fans hungry for an energizing presence up front should keep him on their radar. With his evident strengths and draft pedigree, Harmon tops the list of Steelers picks making the biggest impact this winter.
Kaleb Johnson: The Powerhouse Running Back Steering Pittsburgh’s Ground Game
Running back Kaleb Johnson, the third-round pick out of Iowa, is rapidly gaining recognition for his rare blend of physicality and finesse. Johnson’s running style defies the conventional mold; while he doesn’t possess the towering size of traditional power backs, his aggressive style and unrelenting toughness make him stand out in the Steelers’ offense.
At rookie minicamp, Johnson exhibited a relentless work ethic, revealing a disciplined routine that involved running four miles and hitting the weight room before stepping into his first NFL practice. Such commitment hints at his hunger to carve out a significant role in Pittsburgh’s ground attack.
What truly makes Johnson a prospect to watch is his ability to fit into the Steelers’ zone-heavy scheme seamlessly. He combines speed to reach the edge, the strength to engage second-level defenders, and a fearless approach to contact. Comparisons are naturally drawn to past stalwarts like Najee Harris, whose production set a high bar for rookie backs. Johnson may be smaller, but he runs with a comparable power that is proving to be an invaluable asset.
- Weight: Lean and muscular, with minimal body fat
- Running Style: Physical, outside-zone specialist
- Draft Round: 3rd Round
- Projected Role: RB2 behind Jaylen Warren with potential to challenge for lead duties
- Key Strengths: Speed, power, relentless work ethic
Potential concerns linger around Johnson’s third-down contributions. With limited experience catching passes or excelling in pass protection at Iowa, it remains to be seen whether he can fully take on these roles in an NFL passing offense. Still, his ability to thrive in runs and short-yardage situations provides the Steelers with much-needed stability and explosiveness at the position.
| Attribute | Detail | Notes |
|---|---|---|
| Physical Conditioning | Exceptional | Runs four miles before practices |
| Running Style | Physical/outside zone | Fits Steelers scheme |
| Third-Down Skills | Developing | Yet to prove pass-catching and blocking |
| Competitiveness | High | Leads by energy and intensity |
| Draft Pick | 3rd Round | Strong investment by Steelers |
Given his skill set and preparation, Johnson stands as a leading choice for most impactful Steelers rookie this winter—poised to push past expectations and contribute big plays as the season matures.
Will Howard: The Quarterback with a Heart Set on Pittsburgh
The Pittsburgh Steelers quarterback Will Howard’s journey to the Steel City reflects resilience and a perfect fit for the franchise’s current needs. Drafted late in the sixth round, Howard’s draft night drop could’ve demoralized many, but his reaction was pure enthusiasm and love for the Steelers’ organization. For him, landing in Pittsburgh wasn’t a consolation—it was destiny.
Howard is not your typical high-profile quarterback prospect. His draft slide means his contract came with less guaranteed money, but his eagerness, leadership qualities, and evident passion have already earned respect from coaches and veterans alike. Sometimes, the value of a QB isn’t in the draft round but in the fit and the opportunity to grow within a system tailored to his strengths.
- Draft Position: 6th round pick
- Fit with Steelers: Loves the city and offensive system
- Potential: Projected developmental QB with upside
- Early Impact: Learning, showing leadership and pocket awareness
- Strengths: Composure, work ethic, football IQ
For Pittsburgh, Howard represents a long-term investment that could evolve into a foundational player. While he may not immediately start, the chance to learn behind established players and build confidence suggests big things could be ahead as winter progresses. His story is a reminder that sometimes the biggest impact is off the stat sheet—setting culture and embodying team spirit.

Roc Taylor: The Undrafted Wide Receiver Who Might Be Pittsburgh’s Hidden Gem
Undrafted receivers often face an uphill battle, but Roc Taylor might just rewrite that script for the Steelers in 2025. Towering at 6’2” and weighing 213 pounds, Taylor’s physical presence near matches that of tight ends, which gives him a unique advantage when matched against smaller defensive backs.
While lacking blazing speed, Taylor compensates with polished route running and in-game savvy that has made him a leader among rookies, mentoring even younger players during minicamp. His ability to find soft spots in the defense and use body control to create separation suggests he could be a valuable weapon in the Steelers’ receiving corps.

- Playing Style: Physical, savvy with good route running
- Experience: Played 44 college games at Memphis

His limitations on speed keep some scouts cautious, but his production and attitude leave no clear reasons why he couldn’t become a regular contributor, especially in positional packages demanding physicality and reliable hands. Fans should watch Roc Taylor’s preseason reps closely—he could be one of the biggest surprise Steelers rookie contributors this winter.

Observers noted his blend of size and agility during rookie minicamp, with an impressive relative athletic score placing him in the upper tier among NFL fullbacks.
