Florida State has produced no shortage of NFL talent under head coach Mike Norvell, and the 2026 NFL draft is shaping up to add another name to that growing list. Former Seminoles defensive lineman Darrell Jackson is generating legitimate buzz heading into draft weekend, and the latest projection from ESPN analyst Matt Miller places him squarely on an NFL roster in the fourth round.
Miller’s updated mock draft slots Jackson to the San Francisco 49ers at No. 139 overall — a pairing that, on closer examination, makes considerable schematic sense. For a Florida State program that has worked hard to rebuild its identity as a pipeline for defensive line talent, Jackson’s mock draft placement serves as another data point in that ongoing narrative. His journey from a developmental prospect to a legitimate Day 3 target reflects both his personal growth and the program’s investment in player development at the point of attack.

A Career Built on Growth and Physicality
Jackson’s time in Tallahassee was defined by steady development rather than overnight stardom. He recorded career-best numbers during the 2025 season, totaling 44 tackles, 11 solo tackles, and 33 tackle assists, capping a college career that saw him grow into one of the most physically imposing interior defenders in the ACC.
Scouts are particularly intrigued by his presence in the middle of the defensive line. When he attacks blocks properly, he consumes two gaps — a rare and coveted trait for any interior defender. His most impressive physical attributes are his 11-inch hands and a 7-foot-2-inch wingspan, measurements that give him the tools to control blockers and disrupt passing lanes from the inside.
Why San Francisco Makes Sense
The 49ers operate one of the most sophisticated defensive systems in professional football, and the team has a well-documented history of maximizing interior linemen who bring elite physical tools and a willingness to develop technique. San Francisco’s scheme demands versatility and football IQ at the point of attack, traits Jackson has demonstrated throughout his collegiate career.

Adding a physically unique, run-first interior piece in the fourth round represents low-risk, potentially high-reward roster construction, and Jackson would enter a competition-rich environment that rewards the kind of professional habits he says he is committed to building.
The Scouting Report: Upside and Areas to Address
NFL analyst Lance Zierlein’s overview captures both the intrigue and the developmental work ahead:
“While he’s an enormous interior presence with impressive physical features, Jackson’s inconsistencies are partially rooted in flawed fundamentals and technique. He plays too upright and with inconsistent base width/block take-on, making him more easily cleared from gaps.” Zierlein added that Jackson “could see vast improvement in his shed-and-control with quicker hands, improved upper-body power and a full-time move to odd-front end,” noting that “Jackson’s size and length could be considered unmined gold by some teams.”
It is a scouting profile that reflects genuine upside paired with real work to be done, exactly the kind of prospect a team like San Francisco has historically been willing to invest in.

Draft Outlook
Currently projected as a third-round pick in most evaluations, Jackson’s placement at No. 139 in Miller’s mock represents a slight slide from his consensus value, though fourth-round selections with his physical profile and two-gap capability rarely go unnoticed on an NFL roster.
If the fundamentals Zierlein flagged continue to sharpen and the weight management holds, Jackson has the raw tools to outperform his draft position. For the Seminoles’ top NFL prospect this cycle, the best football of his career may still be ahead of him.
