With the Buffalo Bills introducing a new defensive scheme this season, there have come questions about how the players on the roster fit new defensive coordinator Jim Leonhard’s vision. After former head coach and defensive designer Sean McDermott was fired, the team has seemed to embrace a more physical, aggressive approach in their defensive preparations. Rather than relying on sound adherence to place and assignment, the Bills are prioritizing playing quickly as the assignment.
One of the positions
on the roster that has garnered plenty of discussion is that of the nose tackle. In a 3-down front like Leonhard has implemented, that position is essential to the rest of the defensive line’s success. Truthfully, this isn’t too different from how McDermott’s scheme operated, as the “one-tech” position was analogous to the nost tackle in that it was the spot that allowed the other players on defense to shine. Without a strong player in the middle, the defense is set to struggle.
Do the Bills already have that strong player at the nose? In today’s edition of “91 players in 91 days,” we’ll discuss the team’s presumed nose tackle. Spoiler alert: He’s a stud.
_____________________________________________________________________________
Name: Deone Walker
Number: 96
Position: DL
Height/Weight: 6’7” 331 lbs.
Age: 22 (23 on 3/11/2027)
Experience/Draft: 2; selected by Buffalo in the fourth round (No. 109 overall) of the 2025 NFL Draft
College: Kentucky
Acquired: Fourth-round draft choice
Financial situation (per Spotrac): Walker enters the second year of his four-year rookie contract, which is worth $5,247,040 overall. In 2026, Walker carries a cap hit of $1,266,760 if he makes the 53-man roster. If he’s released, the Bills will carry a dead cap charge of $785,280.
2025 Recap: After a collegiate season where a back injury limited Walker’s explosiveness, he slid all the way to the fourth round in the 2025 NFL Draft. The Bills scooped him up, and they have reaped the benefits since. Walker was excellent as a rookie, playing in all 17 games and serving as a point of consistency in the middle of a defense wrecked by injuries. Walker totaled 39 tackles, eight tackles for loss, four pass knockdowns, four quarterback hits, one fumble recovery, and one sack during the regular season. He played 464 defensive snaps, good for 47% of the team’s total on defense, as veteran Ed Oliver missed nearly the whole season thanks to a litany of injuries. That snap total was the highest among Bills’ defensive tackles, as veteran DaQuan Jones also missed five games. In the playoffs, Walker was still a wrecking ball, and he put together two very good games. He had six tackles, two pass knockdowns, and an interception while generally wreaking havoc on both the Jacksonville Jaguars and the Denver Broncos.
Positional outlook: Walker is set to start at the nose, with DeWayne Carter, Phidarian Mathis (who is suspended for the first three regular season games due to a violation of the NFL’s substance abuse policy), and Zion Logue also playing snaps at that spot. The other defensive linemen on the roster are Tommy Akingbesote, Ed Oliver, Zane Durant, Landon Jackson, Travis Clayton, and T.J. Sanders.
2026 Offseason: Walker is healthy and he has played well this summer. He was only on the field for ten snaps in Buffalo’s preseason opener against the Carolina Panthers, but he was a menace. Walker had a sack, three tackles, two QB pressures, and one tackle for loss.
2026 Season outlook: Buffalo Bills general manager Brandon Beane has done a good job in the middle rounds of his drafts, and it seems like he’s found another mid-round gem in Walker. The big fella is versatile enough where he really could play any role along Jim Leonhard’s three-man front and he’ll find success. That leads to the question of whether the team wants him to be the nose tackle long-term, or do they think it would serve him—and the team—best to play more as a penetrating attacker.
If the Bills were looking at Walker as a traditional nose tackle—think Ted Washington—then Walker will be successful. However, he was at his best last season when he was replacing Oliver as the penetrating three-tech player. An overly simple explanation of the difference in roles comes down to gap responsibilities. A one-tech (or zero-tech, as a nose would be considered) is often expected to control more than one blocker as part of his responsibility. As players go farther away from the middle, many defenses ask those linemen to exploit one-on-one matchups, and those matchups are often exploitable because of the success of the big fella in the middle.
Leonhard’s defense seems to be less concerned about the gap assignments and more concerned with causing chaos in opposing backfields. That should give Walker (and the rest of Buffalo’s defensive line) plenty of freedom to make plays. That freedom was on full display during Buffalo’s preseason opener, and while any exhibition results should be digested with caution, there were plenty of reasons to be optimistic. Walker, both literally and figuratively, was one of the biggest reasons for optimism.
So long as Walker stays healthy, he’s going to have a huge role on the Bills’ defense this season. If his early play is any indication, he might become a household name sooner rather than later.
