Many members of the Chiefs’ defense from the 2023 season are still in place, but a few notable departures have created room for rotational returnees to take on an increased workload. At the linebacker spot and in the secondary in particular, new faces are positioned to ascend to a starter’s role. 
Willie Gay signed a free agent deal with the Saints, leaving Kansas City without a three-year starter on the second level. The team still has Nick Bolton in place for one first-team spot, but Leo Chenal is poised to fill Gay’s vacancy. The 2022 third-rounder is on track to see an uptick in defensive usage, Nate Taylor of The Athletic writes (subscription required).
Chenal has played in all 34 regular season games during his career to date, along with seven playoff contests. During that combined span, he has made 21 total starts but his largest workload so far has come on special teams. The 23-year-old racked up 65 tackles and three sacks last year, adding 15 stops and a forced fumble in the postseason. An increased workload in 2024 would lead to expectations for further growth in pass coverage in particular.
Needing to devote resources to defensive tackle Chris Jones this offseason, the Chiefs tagged-and-traded cornerback L’Jarius Sneed to the Titans in March. That created a notable opening in the secondary, but second-year defensive back Chamarri Conner is a strong candidate to step into a larger role. The 2023 fourth-rounder has experience at multiple spots dating back to his time in college, and he served as a fill-in at safety during his rookie campaign. Taylor notes, though, that in spring workouts Conner took first-team reps at the nickel corner position.
At times, All-Pro corner Trent McDuffie could slide to the inside. During those instances, Taylor writes Conner will likely move to the safety spot, something which will no doubt lead to a notable uptick in usage. The Virginia Tech product was on the field for 28% of defensive snaps in 2023, a figure which could check in much higher this fall. With respect to the perimeter spot opposite McDuffie, Taylor notes Joshua Williams received the most reps during OTAs and minicamp.
The latter has also been a special teams mainstay while seeing part-time usage on defense during his career. Williams, 24, has totaled 58 tackles and 12 pass breakups over his first two years in Kansas City; his coverage statistics saw a notable improvement last season. That could give the Chiefs cause for optimism a first-team role would suit the former fourth-rounder, although Taylor adds that Jaylen Watson is also in the mix for a starting position.
Kansas City’s defense played a central role in the team’s second straight Super Bowl title, and the unit will again face high expectations in 2024. New faces in starting positions could change the Chiefs’ performance on that side of the ball, but their familiarity with DC Steve Spagnolo should lead to a relatively smooth transition.
