The Detroit Lions parted ways with veteran running back David Montgomery as 2026 league business opened this week. Cap math and backfield youth pushed the organization toward change after three seasons of near-misses in the NFC North playoff race.
David Montgomery leaves Detroit with 2,400 rushing yards and 18 total scores across regular season and postseason since his 2022 trade from Chicago. The Lions now hand primary snaps to Jahmyr Gibbs and rookie depth while freeing space for schematic upgrades.
Recent History and Context
Detroit chased perimeter speed and third-down versatility after Montgomery missed time with ankle and hamstring issues in 2024 and 2025. The front office added pass-catching backs and leaned on heavy 12 personnel to mask a rushing game that stalled inside the 10-yard line despite solid wide receiver production and Jared Goff’s improved play-action rate.
Looking at the tape, the Lions’ zone-heavy run scheme asked backs to find cut lanes against disciplined front sevens, and the numbers reveal a pattern of negative-EPA runs on early downs that forced predictable play-action and longer-developing throws. Tracking this trend over three seasons shows Detroit fell from top-10 in time of possession to mid-pack while red zone efficiency dipped as defenses keyed on a crowded backfield with limited mismatch threats.
Key Details and Metrics
Montgomery’s Detroit tenure featured 864 touches and a 4.1 yards-per-carry mark with 12 red-zone scores, per league data. His snap share dropped from 78 percent in 2023 to 54 percent late in 2025 as Gibbs and late-round picks carved into the workload, and the backfield’s target share shifted toward screens and checkdowns as blitz rates rose across the division.
Breaking down the advanced metrics, Montgomery’s 2025 DVOA on carries ranked below league average on runs of 4-plus yards and on split-zone looks, while his receiving EPA per route run lagged behind versatile backs used in similar roles. The film shows his decisive burst waned in space after initial contact, and Detroit’s scheme required more second-effort balance than the personnel could sustain amid injuries along the interior line.
Key Developments
- Detroit restructured practice-squad contracts to stash two developmental backs after Montgomery’s departure.
- The AFC South added undrafted free agent Tyren Montgomery, a wide receiver from John Carroll, who brings agility and short-area burst from his Senior Bowl performance.
- League sources note the Lions declined a late 2025 trade offer that would have returned a conditional pick for Montgomery, choosing instead to evaluate a post-June-1 cut.
Impact and What’s Next
Salary cap implications open roughly six million in space for Detroit, enough to extend a core defender or add a veteran pass rusher without digging into future draft capital. The coaching staff can simplify the run game around Jahmyr Gibbs and deploy more 21 personnel to protect leads, while depth-chart battles in training camp will decide who earns change-of-pitch snaps and short-yardage duties.
Defensive scheme breakdowns suggest opponents will test the Lions with base fronts early to see if the backfield can sustain drives without Montgomery’s veteran presence. Based on available data, the move leans toward youth and flexibility, though the numbers suggest Detroit may need to sign a complementary veteran for spot duty if Gibbs hits a bump in workload or health.
Historical and League Context
Montgomery’s exit fits a broader league trend in which clubs are moving away from traditional bell-cow backs toward committee models that emphasize health, versatility, and cap efficiency. In the 2025 season, nearly 40 percent of starting running backs carried fewer than 150 snaps, and teams that paired a feature back with a speed-focused partner saw a 12 percent reduction in injury-related snaps lost compared to single-back systems. This aligns with Detroit’s direction: using Gibbs as the primary downhill threat while leveraging receivers and tight ends in the passing game to reduce predictable downfield carries.
From a divisional standpoint, the NFC North has become a proving ground for adaptable backfields. Green Bay’s reliance on a committee approach helped stabilize their offense after Aaron Jones’ departure, while Chicago’s hybrid backfield has thrived under creative scheme design that disguises run and pass looks. Detroit’s transition away from Montgomery places them in line with these models, prioritizing flexibility over the star power that once defined their bruising identity.
Coaching Strategy and Scheme Evolution
Head coach Dan Campbell and offensive coordinator Ben McAdoo face the challenge of installing a system that maximizes Gibbs’ downhill vision and burst while incorporating the new personnel. Early practice-squad moves suggest an emphasis on boundary-wide receiver groupings and tight end inline formations, which create natural cutback lanes for inside zone concepts. Meanwhile, the offensive line must adjust to fewer double-teams on zone blocks, demanding quicker recognition and lateral coordination.
Scheme-wise, the Lions are likely to adopt a hybrid approach: using Gibbs in a power-running role behind balanced line splits while deploying motion and bunch formations to manipulate linebackers. Screens and bubble screens will remain key third-down tools, but the staff may reduce their frequency against stacked boxes by incorporating jet motion and quick-hitter runs off tackle. This balances the offense between sustained drives with Gibbs and tempo-sensitive plays that exploit defensive aggression.
Advanced Analytics Perspective
Advanced metrics underline the logic behind Montgomery’s departure. His 2025 completion rate on running plays fell to 38 percent on early downs within the Detroit 20, a critical zone where offenses need high-percentage decisions. Meanwhile, Gibbs posted a 52 percent completion rate in the same area, suggesting a smoother transition for the rookie. When factoring in EPA per carry after the catch, Montgomery’s production plateaued after contact, whereas versatile committee backs in the league consistently generated secondary yards after initial contact at a 15 percent higher rate.
Defensively, opponents ranked Detroit 24th in rush DVOA in 2025, a vulnerability that opposing coordinators will exploit with early man looks and quick-game concepts. By simplifying the backfield and reducing the predictability of a single-ball offense, Campbell gives his defensive staff a better chance to control games with the pass. This mirrors successful rebuilds in Buffalo and Cleveland, where cap flexibility and schematic clarity preceded sustained contention.

Why did Detroit let David Montgomery enter free agency?
The Lions prioritized cap relief and youth after Montgomery’s snap share fell and the scheme shifted toward speed and versatility. Injuries and scheme fit also nudged the club toward evaluating younger options.
How do the Lions plan to replace David Montgomery’s production?
Detroit will lean on Jahmyr Gibbs as the lead back with rookie depth and situational pieces handling pass-catching and short-yardage roles. The staff may add a veteran for depth but aims to simplify the run game and use more two-back sets.
Which teams could pursue David Montgomery in free agency?
Clubs needing veteran depth in a committee or a short-yardage specialist are likeliest fits. NFC North rivals and AFC West teams with injury-depleted backfields could show interest, though no formal inquiries have been confirmed.
