Collin Campbell

Physical Profile

Campbell's calling card is rare frame length: at 6-7 he is among the tallest players on Michigan State's roster, with the arm length and reach to hold edge rushers at a distance. His listed weight has moved between 270 (early 2025 evaluations) and 280-295 (MSU roster and 247Sports senior listing), so the frame still has room to carry 310-plus without losing mobility. Greg Biggins of 247Sports grades him a plus athlete with lateral mobility and get-off that translate cleanly to tackle. The flag is flexibility: at his height, hip and ankle bend are the difference between winning with leverage and getting stood up by shorter, lower-pad-level rushers.

Play Style

Campbell played left tackle as a junior and senior and is a tone-setting run blocker first. On film he fires off the ball, drives defenders off their spot, and looks to finish through the whistle rather than stalemate. He is comfortable in space, reaching linebackers on climb blocks and getting out in front on sweeps and pulls, which is uncommon for a 6-7 prep tackle. In pass protection he relies on length and lateral mobility to stay square and mirror; he wins when he lands his hands first and loses when a shorter rusher gets under his pads. The overall profile is a developmental left tackle with an aggressive edge rather than a finesse technician.

Strengths

• Prototype Big Ten tackle length at 6-7 with room to add 25-30 pounds; the frame alone is why Michigan State, Utah, Arizona, and Arkansas offered, and why a top-200 composite rank held while playing at a modest weight.
• Finishing temperament as a run blocker: 247Sports notes he 'loves to bury his man into the ground' and brings genuine nastiness to the trenches, which shows up on the second-level and pull/sweep reps in his junior film at left tackle.
• Athleticism for a player his size: get-off, lateral slide, and mirror ability in pass protection are already functional, and he has the movement skills to execute reach blocks and pulls in a zone or gap scheme.
• Coaching pedigree and technical foundation: his father Steve Campbell, a former Arizona State quarterback, is his high school head coach, and evaluators describe him as more technically sound than most prep tackles, with SI's MSU preview calling him 'closer than most' young tackles to college-ready.

Areas to Improve

• Mass and functional strength: he arrived around 280, and starting-caliber Big Ten tackles play at 300-plus. Anchor strength against bull rushes is the single biggest gap between his current body and a starter's.
• Flexibility and pad level: Biggins specifically cites flexibility as a development area. Tall tackles who cannot sink their hips get walked back and lose leverage in the run game against low-leverage interior defenders.
• Technical consistency: evaluators still describe him as 'far from a finished product' and 'raw in some areas,' meaning hand placement, punch timing, and set depth need reps against college-caliber speed.

College Projection

He is a true freshman reserve tackle for Michigan State in 2026 behind established starters Ben Murawski (LT) and Conner Moore (RT), with Rustin Young and Robert Wright Jr. also in the tackle rotation. The realistic path is a redshirt or limited-rep 2026, a weight-room year to reach 305-310, and a push for a starting tackle job in 2027 or 2028 as the current starters cycle out. His length and athletic baseline give him a higher floor than most freshman tackles, and a three-year starting run is the expectation if the added mass comes without losing mobility.

NFL Outlook

Legitimate NFL-frame prospect. 6-7 tackles with 34-plus-inch arms, lateral mobility, and a mean streak get drafted when they reach 310 and show anchor strength. The 2029-2030 draft window is the target if he becomes a multi-year Big Ten starter. Day-two ceiling if the flexibility and pass-set technique catch up to the frame; if hip stiffness persists he projects better inside at guard, where length is a luxury rather than a requirement.

Best Fit

Michigan State under Pat Fitzgerald is a good schematic fit: a physical, run-first Big Ten offense that values length at tackle and can afford to let him develop for a year. His pull-and-sweep athleticism suits a gap/power run game with inside-zone mixed in, and the Big Ten's power-rush edge defenders will force the anchor and pad-level development he needs. The staff's patience matters more than scheme here; the tools are those of a future left tackle, and the program that lets him redshirt and add 25 pounds before starting will get the best version.
