Campbell is a bowling ball in a phone booth — a thick, powerful guard who mauls defenders at the point of attack and creates genuine movement in the run game when blocking downhill. His anchor is legit and his pad level is naturally low, which lets him neutralize power rushers despite being slightly undersized for the position. The concerns are real, though: his feet are heavy in pass protection, his hands come up late and wide inviting holding penalties (10 flags in 2025 alone), and his lateral agility caps his effectiveness against NFL-caliber interior speed. In the right gap-heavy scheme he's a plus starter; in a system that asks him to mirror or reach, he could be a liability. The 5.01 combine 40 was eye-popping for his size, but until that straight-line speed translates to better play in space, the projection carries meaningful risk.
- Dominant downhill run blocker who creates genuine vertical displacement at the point of attack with elite lower-body power and natural leverage
- Reliable anchor in pass protection — natural knee-bender with low pad level who absorbs bull rushes and re-anchors when initially beaten
- Effective puller who reaches, kicks out, and logs defenders in gap-scheme concepts, opening clean running lanes consistently
- Veteran experience (43 career starts) with strong stunt recognition and communication, especially impressive as the only returning starter on Texas's 2025 OL
- Mean streak and relentless effort — consistently looks for work, blocks multiple defenders per play, and finishes with nasty intent
- Heavy feet in pass protection — labors in kick-slide and struggles to mirror athletic interior defenders or pick up delayed blitzes through gaps
- Hands come up late and wide, allowing defenders into his frame; tendency led to 10 penalties in 2025 and poor one-on-one reps at the Shrine Bowl
- Stiff hips limit recovery ability when initially beaten and create awkward lunging when forced to redirect quickly or block on the move
- Limited positional flexibility — 2,633 of 2,635 career snaps at right guard with essentially zero experience elsewhere on the line
Steelers Depot's Alex Kozora comp nails it — both are wide-bodied, powerful interior maulers who dominate in gap schemes with raw strength and physicality but lack the foot speed and lateral agility to be scheme-versatile. Simpson carved out a starting role in Las Vegas/Green Bay by leaning into his power advantages while needing scheme accommodation for his athletic limitations.
