Lions, not Dan Campbell, under fire as defensive collapse risks Super Bowl window

Four weeks into the 2026 season, the Detroit Lions find themselves with one of the NFL’s worst defenses and a head coach who insists the answers are already in-house. Despite sitting at the bottom of the league in both points and yards allowed, Dan Campbell is standing firm behind defensive coordinator Kelvin Sheppard and the current structure of his staff.

The latest warning sign came in Sunday night’s 32-26 loss to the Carolina Panthers. Bryce Young, who entered the game as the league’s passing leader, shredded Detroit for 329 yards. Wide receiver Tetairoa McMillan delivered a career outing with 14 catches for 192 yards and two touchdowns, while running back Chuba Hubbard added 122 rushing yards and two more scores as Carolina repeatedly moved the ball at will.

Campbell stays loyal to Sheppard as results sag

Speaking after the defeat, Campbell acknowledged the defense as a glaring issue but dismissed talk of a coordinator change. He emphasized improving "with what we’ve got," pointing to weekly tweaks and untried wrinkles rather than a sweeping overhaul of scheme or leadership.

Players have echoed that message. Linebacker Jack Campbell backed his coordinator, saying that Sheppard works hard and that both he and Dan Campbell believe in him, stressing the need to stay the course and stick together. The show of confidence comes even as the unit has regressed sharply since Aaron Glenn departed to become head coach of the New York Jets; under Glenn, Detroit climbed each year in the standings, peaking with a 15-2 season and a divisional-round appearance.

Elite offense dragged down by failing defense

The contrast with the Lions’ offense is stark. Detroit boasts premier talent across that side of the ball: Jahmyr Gibbs as a top-tier running back, Penei Sewell anchoring the offensive line, Amon-Ra St. Brown among the league’s better receivers and Sam LaPorta off to a strong start at tight end. Quarterback Jared Goff just recorded the seventh 400-yard passing game of his career and his third since arriving in Detroit.

Yet those performances have not been enough to consistently overcome the defense. The Panthers, New York Jets, Buffalo Bills and New Orleans Saints have all scored at least 24 points on the Lions so far, with New Orleans piling up 30 after halftime and in overtime of the season opener. Detroit followed last season’s step back to 9-8 and a missed postseason by starting 2026 at 2-2, a mediocre mark for a team built to contend.

Injuries and departures on the back end have contributed. Safeties Kerby Joseph and Brian Branch are unavailable, and Terrion Arnold’s late-offseason exit left the secondary thin. Up front, however, the Lions still field Pro Bowl-caliber pieces in Aidan Hutchinson and Jack Campbell, raising questions about how effectively the group is being deployed. Unless Detroit upgrades its defensive personnel or rethinks its leadership, the league’s worst unit risks undermining an offense that looks ready to compete for a Super Bowl now.
