Massive nose tackle whose lack of productivity belies his potential to imprint on NFL games as a run defender. Jackson is a complete non-factor as a rusher, so his spot on a draft board will be relative to a team’s willingness to take a two-down player in need of polish. He’s long and plays with extremely heavy hands and an ability to overwhelm single blockers at times. When he’s allowed to swap paint and focus on smaller areas of containment, he’s a tough out. He gets knocked off his spot more than he should, but better block take-on and technique should create better consistency. Jackson has freakish size and is a more enticing prospect when tape flashes are prioritized in the evaluation process.
