2025 Nebraska Football Position Previews: Defensive Line

Nebraska’s defensive line might be the most exciting swing factor on the roster this fall because the group blends real versatility with the kind of short-area juice that shows up as disruption. Yes, Ty Robinson is gone, and that’s a big presence to replace, but the current room gives John Butler options Nebraska didn’t always have a year ago. The expectation isn’t just to be sound—it’s to be louder at the line of scrimmage, to create more negative plays, and to squeeze quarterbacks into hurried throws.

If you’re hunting for a breakout, start with Keona Davis. His practice tape jumps for all the right reasons—explosiveness out of his stance, the ability to win in tight spaces, and a closing burst that ruins blocking angles. That’s the profile of a lineman who can tilt a series by himself. Pair that with Riley Van Poppel’s next-step development inside and Elijah Jeudy’s returning size and savvy, and you begin to see a front that can both hold point on early downs and still threaten backfields when it’s time to hunt.

The edges add shape and ceiling. Cameron Lenhardt brings functional strength and relentlessness that offenses feel in the fourth quarter, while blue-chip newcomer Williams Nwaneri gives Nebraska something it hasn’t always had in recent seasons: a long, explosive threat who changes protection plans on Tuesday and down-and-distance on Saturday. Mix-and-match those five and you can play multiple without wholesale substitutions—kick Lenhardt inside on passing downs, stand Nwaneri up, slant the front with Davis chasing from the backside, and suddenly the picture shifts faster than offenses want to process.

That’s the difference between solid and special. The first two years of the Rhule era gave Nebraska honest, assignment-sound line play; what’s been missing is consistent havoc—hits, hurries, sacks that steal possessions. This rotation has the athletes to raise that ceiling. If Davis turns flashes into production, if Van Poppel and Jeudy give you dependable interior wins, and if the young edge talent forces protections to slide, the downstream effects touch everything: linebackers run free, the secondary triggers faster, and third-and-manageables become third-and-long.

Depth will decide how far it goes. Nebraska doesn’t need one star so much as a wave—six, seven bodies who keep the standard high when the game turns into a 70-snap grind. If the rotation holds and the group stays healthy, this line stops being a talking point and starts being an identity. That’s how you turn Saturdays: by living on the other side of the line of scrimmage and making offenses play your game.
