McClellan is a big-bodied, scheme-versatile interior defender who wins early in the rep with a surprisingly quick first step for a 315-pound man and finishes with heavy hands at the point of attack. His run defense is legit — he holds gaps, stacks and sheds single blocks, and pursues with a motor that belies his size — but his pass-rush upside is capped by inconsistent pad level that lets NFL guards put him on skates and a counter-move repertoire that's still more flash than substance. The Senior Bowl confirmed his floor as a rotational early-down nose who can control gaps in any front, but the ceiling of a starting 3-technique depends entirely on whether his leverage and conditioning issues are coachable or structural. He's a Day 3 bet on physical tools and competitive toughness, with a narrow but real path to starter reps if the technique catches up.
- Excellent size/length combination (6-3⅜, 315 lbs, 34-inch arms, 11-inch hands) with positional versatility from 0-tech to 4i alignment
- Surprisingly explosive first step for an interior lineman that creates quick penetration on both run and pass downs
- Strong grip and hand power in one-on-one run defense situations — stacks, locks out, and sheds effectively against single blocks
- High motor and competitive toughness with excellent pursuit angles and awareness to recognize screens and swing passes
- Scheme diversity — can two-gap in odd fronts or penetrate in even fronts, and loops effectively on stunts and twists
- Inconsistent pad level is the primary liability — tendency to pop upright at the snap compromises his anchor, play strength, and block-shedding ability
- Limited and developing counter-move repertoire as a pass rusher — bull rush is the go-to, but when it stalls, he lacks reliable secondary options
- Gets driven off the line by double teams when leverage is poor, making him a liability on passing downs without a rotation
- Conditioning concerns — appeared to gain weight late in the season, and may need to be managed in an active DL rotation rather than playing 60%+ snaps
Steelers Depot directly comped him to Mathis — both are versatile two-gapping defenders with solid power rush ability who need to improve snap quickness and handling of lateral blocks. Similar body type, similar run-defense-first profile with pass-rush upside dependent on technique refinement.
