Massive man with evenly distributed body weight that will have him pegged as a nose in either even or odd fronts. While the traits say run-plugger, the tape does not. He doesn't control the point of attack with power and frequently gave ground to double teams and angle blocks. He has the power to handle single blocks and might be able to strengthen the anchor if his bend and leverage can be improved. He's a try-hard rusher whose athleticism creates more pressure than expected. He has late-round value and might become a developmental prospect on a practice squad.
Campbell's 2019 tape is better than his 2020 film, but it still might not be good enough for the next level. He isn't explosive off the snap and lacks natural athleticism to make up for it. Below-average knee bend will get him pushed around the field as a run defender and he doesn't have the skills to create flash plays as a pass rusher, which makes it hard to envision a team getting excited about how he'll project with more coaching.
