The Arizona Cardinals have turned to veteran cornerback Sean Murphy-Bunting to fill a pressing vacancy at the nickel spot as the roster adjusts to Garrett Williams’ recovery from a torn Achilles sustained late last season. With Williams sidelined and rehabbing, Murphy-Bunting has spent the early portion of offseason work lining up more frequently inside, spending time with the safeties group as the team evaluates depth and prepares for the regular season.
Murphy-Bunting’s shift to the slot is an immediate, practical response to a gap created by Williams’ absence. The nickel — a defensive back who typically covers opposing slot receivers, supports run defense on the edges and is asked to read routes quickly in tight spaces — often requires a blend of quickness, instincts and familiarity with the defensive scheme. By inserting a veteran with prior experience at the position, Arizona’s staff can run more situational packages in practice, stress-test matchups against the offense and preserve other young corners for their developmental reps while Williams continues his rehabilitation. Coaches are monitoring Williams’ progress closely; his recovery from a torn Achilles will determine how long Murphy-Bunting’s inside work remains the primary plan and when the team might restore Williams to a regular role.

Murphy-Bunting described the move back to the interior of the defense as a return to a role he first learned early in his career. “For me, that’s kind of where I started my career I guess I would say,” he told Arizona Sports’ Bickley & Marotta. “I had opportunities bouncing back and forth from inside to outside and outside to inside, but I think I’ve had most of my success, or most of my playmaking I guess, from the inside.
“It just gives me an opportunity to be around the ball and utilizing my brain where I kind of play to the scheme but also play to my abilities and do whatever the team needs me to do in that regard.” Those remarks came as the Cardinals conducted on-field sessions in Tempe, where coaching staff are reworking alignments and testing options at multiple positions while continuing to monitor Williams’ rehabilitation progress.
The Cardinals’ on-field work in Tempe has served as a controlled environment for reassigning responsibilities and integrating veterans into new alignments. With Murphy-Bunting spending reps with the safeties group and inside defensive personnel packages, coaches can evaluate how his communication with the secondary and linebackers affects coverage calls and run fits. Those practice reps also allow younger players to see veteran tendencies up close and provide the staff film-based evidence to guide depth-chart decisions once full-contact drills begin.

Murphy-Bunting’s early NFL seasons underscore the logic behind Arizona’s decision. In his first two professional seasons with the Tampa Bay Buccaneers he operated more frequently from the slot and produced some of his best work there, including a postseason run that featured three interceptions and five passes defensed on the way to a Super Bowl title in 2020. As a rookie he also compiled three interceptions and eight passes defensed. After that stretch he transitioned to a more outside-oriented role across several stops — with the Buccaneers in subsequent seasons, a one-year stint with the Tennessee Titans in 2023 and his initial season with the Cardinals in 2024.
Those early accomplishments in Tampa Bay provide the Cardinals a proven blueprint: putting Murphy-Bunting inside has precedent and has previously resulted in high-leverage plays. His experience in a Super Bowl-winning environment and familiarity with the requirements of slot coverage give the coaching staff reason to believe he can step into the role with minimal acclimation time. That continuity matters most in the early stages of the regular season, when preparation windows are short and reliable play from the nickel spot can influence defensive consistency on third downs and in two-tight end formations.
The veteran missed the 2025 campaign because of injury, but since returning to action he has continued to show playmaking ability even when aligned out wide, recording at least two interceptions and five passes defensed since 2023. Arizona’s coaching staff believes moving him back inside not only fills an immediate need while Williams continues to rehab, but also places Murphy-Bunting in scheme responsibilities that match his strengths.
Murphy-Bunting’s recent production after returning from injury — including interceptions and passes defensed over the past two seasons — supports the Cardinals’ confidence that he remains a playmaker capable of contributing in varied roles. While the outside work demonstrated his versatility, the decision to move him inside underscores the coaching staff’s assessment that his instincts and tendencies align well with the slot responsibilities they want to emphasize this season.
Defensive coordinator Nick Rallis addressed the decision during the final round of organized team activities, saying the move was rooted in roster realities and past experience. “We just felt like that was best for where our roster is at right now,” Rallis said. “It’s something that he did back in Tampa as well. So, we knew he had the ability to do it. We just had to kind of get him back into that mode, because it had been several years in a row, he’d been out there at corner only. He’s very natural inside, so he can play both those spots.”
Rallis’ comments frame the move as both pragmatic and strategic. By invoking Murphy-Bunting’s past slot work in Tampa Bay, the coordinator tied the decision to proven performance rather than experimentation. The reference to getting the player “back into that mode” acknowledges the practical coaching work required to shift a veteran’s technique and alignment — from press-man outside techniques to the spatial awareness and wedge-fitting that slot play often demands — while also signaling confidence in Murphy-Bunting’s adaptability.
From a roster-management perspective, Murphy-Bunting’s availability inside answers an immediate question for Arizona as it balances depth across its secondary. The Cardinals entered the offseason aware they would likely need a fill-in for Williams while the young cornerback works through the recovery process, and Murphy-Bunting’s familiarity with interior responsibilities presents a straightforward internal option. The veteran’s presence also gives the coaching staff flexibility during practices and preseason work as they sort out personnel and situational packages.
Beyond the immediate replacement value, the move simplifies short-term roster planning. Relying on an experienced internal option reduces the need to allocate significant reps to less proven players during critical evaluation periods and allows the team to use practice repetitions to refine coverage calls, blitz packages and matchups that involve the slot. That structure can be especially important as teams prepare for the varied route concepts and motion-heavy offenses they will face in the regular season.
Murphy-Bunting is entering a contract year, a detail that adds context to his increased snaps and the club’s willingness to deploy him in a role he has previously occupied. For Arizona, the approach allows the team to deploy a player with proven production in the slot while monitoring Williams’ return timetable. For Murphy-Bunting, it is an opportunity to reestablish himself in a role that produced some of his most notable plays early in his career, including during the Buccaneers’ 2020 postseason run.
A contract year often carries dual incentives: the team gains shorter-term flexibility while the player has a clear opportunity to showcase value for future negotiations. In this case, Murphy-Bunting’s snaps inside give him a chance to demonstrate coverage consistency and playmaking in a role that historically drew out some of his better film, while the Cardinals can observe how that performance fits into their long-term secondary plans and salary considerations.
As the Cardinals advance through the offseason calendar and into training camp, the nickel position will remain an area to watch. Murphy-Bunting’s move inside has already become a regular sight at team sessions in Tempe, and coaches will continue to evaluate how those alignments translate to game situations once pads come on and preseason competition begins. For now, Arizona’s plan is clear: use a veteran who has played the role effectively in the past to bridge the gap while Garrett Williams completes his recovery, then reassess as the season approaches.
The assessment process will accelerate as contact drills and preseason games provide more realistic stressors — such as timing with pass rush, communication under noise and live route combinations — that can reveal strengths and weaknesses not always visible in non-contact work. How Murphy-Bunting performs in those live settings, and how Williams’ rehab progresses, will dictate whether the inside assignment remains long-term or whether the Cardinals will pivot to other options as the regular season roster is finalized.
Social Media Activity on X
Discussion of Murphy-Bunting’s return to the nickel role has been minimal on X during the early offseason window, with most Cardinals-related conversation focusing instead on broader roster depth, upcoming preseason schedule speculation, and Williams’ rehab timeline rather than specific positional tweaks. No major verified accounts or player-initiated threads have driven notable engagement or new details beyond what has already been shared in local reporting.
That low level of immediate social traction may reflect the timing — early offseason coverage often centers on macro roster questions and recovery updates — but fan interest could grow as training camp approaches, pads come on and preseason snaps provide clearer indications of how the nickel experiment will play out in live-game situations.
