Collin Campbell

Physical Profile

The height is the separator. At 6-7 with a wide-shouldered, long-levered build (listed 270-280 across the cycle), Campbell has the length to play the edge of the line rather than being projected inside, which is the single biggest question for most tall high school linemen. Reports credit him as a plus athlete who gets off the ball, and he has enough short-area quickness to be trusted pulling and leading on perimeter runs. The frame is currently rangy rather than filled out: 280 pounds distributed over 6-7 means light play weight and a torso that gives up leverage to compact interior rushers. There is obvious room to carry 305-315 without losing the movement skill, and he is a legitimate blue-chip body once he does. His pad level and hip/ankle flexibility have to catch up to the height, which is the recurring note in his evaluations.

Play Style

An aggressive, downhill run blocker who plays with intent. He fires off the ball, attacks his landmarks and looks to finish — the temperament is ahead of the technique, which is the preferred order for a developmental lineman. In the run game he is at his best working in space: pulling, executing reach and climb assignments, and covering ground to the second level, where his length lets him cut off angles most tackles cannot reach. In pass protection he sets with adequate width and can mirror speed, but he currently protects with length and effort more than with an anchor, and he will occasionally rise out of his stance and lose the leverage battle against power. The film reads as a high-floor movement athlete who has not yet been asked to win with refined hands or a settled base.

Strengths

• Rare positional length for the region — 6-7 with true tackle proportions, the kind of frame that projects to the left side rather than a forced move to guard, and the reason he graded No. 20 among tackles nationally.
• Run-blocking demeanor and finish. 247Sports' Greg Biggins credited him with 'the kind of nastiness you have to have to excel' in the trenches; on film he regularly drives defenders off the spot and works to finish downfield rather than disengaging at contact.
• Second-level and pull mobility. He gets off the ball cleanly and has the range to execute pulls, sweep responsibilities and climbs to linebackers — unusual functional movement for a player this tall, and the trait that makes him scheme-flexible.
• Adequate lateral slide and mirroring in pass protection already, meaning he does not have to be rebuilt from zero as a pass blocker.
• Coaching pedigree and football IQ. Son of Steve Campbell, a former Arizona State quarterback and his head coach at Williams Field; he was a first-team All-Region and All-Academic selection as a junior and a Fiesta Bowl All-State pick, and he showed maturity by holding his commitment through the departure of his primary recruiter, OL coach Jim Michalczik.

Areas to Improve

• Play strength and mass. At roughly 280 pounds on a 6-7 frame he will get walked back by Big Ten interior power and long-armed edge rushers until he adds 25-35 pounds of functional weight; this is the gating item on his playing timeline, not technique.
• Flexibility and pad level. Tall tackles win or lose on ankle and hip mobility — he needs to sink and anchor rather than bending at the waist, and Biggins explicitly tied his next jump to 'technique and flexibility' continuing to improve.
• Hand technique and consistency. He is described as 'far from a finished product and still raw in some areas' — hand placement, strike timing and re-fitting on secondary contact all need refinement against college-caliber rush plans.
• Level of competition. Arizona 8-4 open-division football is a real but not elite proving ground; his tape features fewer legitimate P4-caliber pass rushers than a Texas, Georgia or Florida counterpart's would.

College Projection

A redshirt-year developmental tackle with starter upside by year three. Realistic timeline at Michigan State: 2026 spent in the weight room adding mass with scout-team and situational work, a swing-tackle/depth role in 2027, and a competition for the starting left or right tackle job in 2028 as a redshirt sophomore. He arrives as the highest-rated member of MSU's 2026 class and joins fellow 2026 tackle Eli Bickel, so the room is being rebuilt around his timeline rather than asking him to play early. The variable to monitor is coaching continuity — the OL coach who recruited him, Jim Michalczik, has departed, and technique-dependent developmental linemen are the players most affected by a position-coach change. Multi-year starter is the expected outcome if the weight gain and flexibility work land.

NFL Outlook

Legitimate but back-loaded Day 2-3 draft potential, contingent almost entirely on development. The pre-draft traits scouts pay for — 6-7 height, long arms, movement skill in space and a finishing mentality — are already in place, and tackles with that combination get drafted on projection. What separates him from a Day 3 flier is whether he can carry 310-plus pounds while retaining his current mobility and develop a true anchor. If he becomes a three-year Big Ten starter at left tackle, a 2030-31 second-to-fourth-round grade is a reasonable target; if the flexibility and mass do not come together, the likely floor is a guard/right-tackle swing body and a priority free-agent or late-round outcome. Too raw to project higher with confidence today.

Best Fit

A wide-zone/outside-zone offense with gap-scheme pulls mixed in — exactly what Michigan State runs, and the reason the fit was mutual. He needs a program that will redshirt him, has a serious strength and nutrition infrastructure to add 30 pounds without sacrificing movement, and employs a technique-first offensive line coach who will invest a full year in his hands and pad level. Systems that ask their tackles to move — reach blocks, pulls, climbs to the second level — maximize his current athleticism while the power development catches up. He is a poor fit for a program needing an immediate plug-and-play starter or a drop-back, pure-pass-protection offense that would expose his anchor before he is ready.
