Kansas Is Counting On A Bigger Edge To Fix Its Run Defense

Kansas Jayhawks' defensive ends are packing on pounds to enhance their run-stopping power and strategic edge, as they focus on size and strength gains for the upcoming season.

Kansas is looking a lot sturdier off the edge this fall, and the change starts with two transfers who arrived at very different sizes and ended up meeting in the middle.

Leroy Harris III came to KU in the spring of the 2025 offseason at 230 pounds. Alex Bray, who also joined during that transfer window, had played at 270 pounds at Illinois.

Now the gap is basically gone. Defensive coordinator D.K.

McDonald recently listed Harris at 274 pounds, and Bray said he sits somewhere between 265 and 270.

“Yeah, he put on size pretty quick,” Bray said of his teammate. “He’s a monster now.”

That added bulk is a big part of the Jayhawks’ plan up front. Last season, McDonald pointed to a defensive end who was 225 pounds, a body type that fit better on the edge than inside.

This year, Kansas is leaning into heavier ends and the results are showing in the numbers on the roster. Strength coach Matt Gildersleeve has said the defensive line is 11 pounds heavier on average than it was a year ago.

Defensive ends coach Joe Dineen made it plain why that matters.

“I think to stop the run - outside zone’s a big one - you got to create knockback on the front side, you got to squeeze things down on the back side, and having two guys that are 270 that are hard to move, that creates knockback on the front side of these runs,” Dineen said. “And if we can do that consistently, big people beat up little people … Shoot, that’s like Darwinism or something.

That’s like evolution, right? So we got to keep them big.”

Bray is no stranger to playing on the larger side. He came out of Marquette High School in Chesterfield, Missouri, and after transferring from Illinois he said part of the appeal at Kansas was getting more chances to work on the edge. He played in all 12 games last season as Justice Finkley’s backup and finished with 21 tackles.

This year, Bray says the biggest jump has come between his ears.

“I’d say I have the strength and stuff,” Bray said. “It’s been there for me.

I’ve been in college football for a while. So just taking what I learned from the classroom, because you know, D-end, you have a lot going on, especially at our ‘stud’ (strong-side) position, where you can be from a 3-tech to a 5 out in coverage, so taking what I learned from the classroom and applying that to the field has helped me more so mentally.”

He’s also stepping into a leadership role. Bray is the only senior on the defensive line this year, though he recently picked up another year under the NCAA’s new eligibility model. Even so, he said he plans to approach 2026 as if it were his last season.

“During spring ball, they kind of pushed - I wouldn’t say pushed, but they wanted a couple guys to step up, and I felt like I took that role, commanding the defense sometimes when it comes to walkthroughs, making sure that we’re all there,” Bray said. “When it’s the D-ends, making sure the younger guys are getting extra work, helping them out, so I feel like that’s kind of a step I’ve taken through this past year, so yeah, that’s kind of big.”

Harris, meanwhile, has been focusing on the finer points after adding the weight so quickly. Dineen said the combination of size and athleticism can become a serious weapon if Harris keeps sharpening the rest of his game.

“With that size, with that athletic ability,” he said, “if you can match that and pair that with great technique and great violence, then the sky’s going to be the limit.”

Harris said his work is centered on becoming more complete.

“Just my all-around game, whether it be the pass rush, setting the edge, sparking gaps. Just trying to be a master of my craft, work on my details.”

Kansas has more than just those two bodies to lean on, too. Michigan State transfer David Santiago, redshirt sophomore Dakyus Brinkley and others give the Jayhawks a deeper, bigger group at defensive end than they had before.

Bray put it simply: “You can’t be too small,” he said. “I would say last year we had some D-ends that were smaller, but I would say our lightest D-end’s probably 245 … Sleeve’s done a good job of putting size on, emphasizing the nutrition. I remember last year we didn’t have this, but this year we drink protein shakes right in the weight room when we’re done with the workout to make sure that we’re putting on size, we take creatine right after, all that good stuff.”

It all fits into a larger push the Kansas staff made across the roster this offseason, using both the transfer portal and internal development to add size throughout the lineup.

“I remember Sleeve put on the board of the weights from last year to this year,” Bray said. “… It’s crazy to see how far we’ve come, how much we’ve emphasized it.”

Lance Leipold Still Has Big Decisions To Make On KUs Defense

Kansas coach Lance Leipold got a closer look at the defense during the Jayhawks ninth practice, and the early read was encouraging on that side of the ball. The offense was more uneven, but the defensive groups gave Leipold a chance to watch how several position battles are developing, especially at defensive end and safety, where the competition has remained open through camp.

Leroy, Alex and David Santiago are among the names in the mix at defensive end, while Dak Brinkley, Garrett Martin, Corey Gordon Jr. and Taylor Davis are part of the safety conversation. For Leipold, those spots still have to sort themselves out, and the next stretch of practice will matter as Kansas keeps evaluating who can handle bigger roles when the season gets here.

Bill Selfs Tyran Stokes Comparison Will Have Kansas Fans Talking

Kansas has added another major jewel to its recruiting haul, securing Tyran Stokes, the No. 1 player in the class of 2026 and the programs second straight year landing the nations top recruit. For a fan base that has become accustomed to big names on the way in, this one carries extra weight because Stokes arrives with the kind of national reputation that immediately raises expectations before he ever steps on campus.

Bill Selfs comparison of Stokes to Andrew Wiggins and Josh Jackson only adds to the buzz, since both were elite athletes with real scoring ability during their Kansas stops. Stokes is already viewed as one of the most talented prospects in the country and, according to 247Sports, ranks as the second-highest rated recruit in Kansas history, which gives this commitment the feel of another major talent swing for a program that keeps aiming at the top of the sport.

Kansas Secondary Faces A New Nickel Twist Right Before The Opener

Kansas entered camp expecting the nickel cornerback spot to be one of the more straightforward pieces of the secondary, but that plan has changed as the opener approaches. Lance Leipold said the competition has opened up, and true freshman Trey Brown has emerged as a steady presence after arriving with the kind of recruiting profile that usually points to a developmental role rather than immediate snaps.

Brown was not supposed to be pushed this quickly into the mix, yet health issues and injuries around the cornerback room have given him a real chance to climb the depth chart. Leipold pointed to Browns work ethic and willingness to learn during fall camp, and those traits have mattered as Kansas sorts out who can hold up at nickel when the games start to count.
