The Detroit Lions didn’t just lose to the Carolina Panthers on Sunday night. They provided more evidence for a defensive problem that is becoming increasingly difficult to ignore.
After watching Detroit’s defense struggle during the 32-26 loss, former Lions cornerback Darius Slay offered a brutally simple assessment on social media.
“Bad bad.”
After what happened at Bank of America Stadium, it’s difficult to argue that Slay was being overly harsh.
The Lions entered the season with expectations of competing near the top of the NFC, largely because of an offense capable of putting points on the board against almost anyone. But the defense has repeatedly forced Detroit into shootouts, and Sunday night’s loss showed what can happen when the offense isn’t able to carry the team.
Bryce Young exposed another problem for Detroit
Carolina quarterback Bryce Young entered the game having already thrown for 939 yards through the first three weeks of the season.
He left Sunday’s game having added another impressive performance to his 2026 campaign.
Detroit’s secondary struggled to contain Carolina’s passing attack, while the defense repeatedly had difficulty getting off the field.
The Lions have now shown a troubling pattern early in the season. Tyler Shough threw for 400 yards against Detroit, while Geno Smith completed 31 of 37 passes with three touchdowns.
Those performances came despite Detroit winning two of those games.
Against Carolina, however, the defensive issues finally became too much to overcome.
Injuries aren’t helping Detroit
To be fair, Detroit’s defense is dealing with significant personnel problems.
The secondary has been hit particularly hard by injuries, leaving the Lions with considerably less depth than they expected to have entering the season.
That puts even more pressure on players such as Aidan Hutchinson and Alim McNeill to consistently create pressure up front.
But injuries don’t explain everything.
There have also been communication and execution problems that have left Detroit vulnerable to plays it should have been prepared to defend.
Carolina’s decision to move Tetairoa McMillan into the slot was one example. The Lions appeared confused by the adjustment, allowing the Panthers to exploit a matchup that Detroit never seemed to fully solve.
Linebacker Jack Campbell has also struggled to provide the consistency expected from an important piece of the defense, while first-round pick Tyleik Williams has yet to make the type of jump many expected.
Detroit’s offense can’t keep covering for the defense
This is ultimately the biggest concern.
The Lions have one of the league’s more dangerous offensive cores with Jared Goff, Jahmyr Gibbs and Amon-Ra St. Brown.
When that group is clicking, Detroit can overwhelm opponents.
But the offense cannot realistically be expected to score 30-plus points every week just to give the Lions a chance.
Sunday’s game was a reminder of that.
Detroit scored 26 points and still lost because the defense couldn’t do enough to slow Carolina down.
That’s particularly concerning for a team with legitimate aspirations of making a deep playoff run.
The defense needs answers quickly
There isn’t an obvious overnight solution.
Detroit cannot simply replace an entire secondary because of injuries, and there isn’t a magical defensive adjustment that will suddenly eliminate every problem.
That puts pressure on the coaching staff to get more out of the players currently available.
The pass rush will also be crucial.
Hutchinson has already recorded 3.5 sacks through the first three games of the season, and Detroit’s defensive front entered the Panthers matchup near the top of the league in sacks.
Generating pressure is one of the simplest ways for Detroit to help a struggling secondary.
If the Lions can consistently make opposing quarterbacks uncomfortable, the defense has a chance to survive its personnel issues.
If it can’t, the same problem will continue following Detroit into every shootout.
Slay’s criticism hits differently
Darius Slay knows what a good Lions defense is supposed to look like.
He spent seven seasons in Detroit and became one of the most recognizable defensive players in franchise history.
So when Slay watched Sunday’s performance and simply described the defense as “bad bad,” Lions fans had plenty of reason to pay attention.
The bigger issue isn’t whether Slay’s assessment was too harsh.
It’s whether Detroit can prove him wrong.
The Lions still have enough offensive firepower to make this season exciting. But if the defense continues allowing opposing quarterbacks to dictate games, Detroit may find itself playing far more close games than its talent level suggests.
The offense can keep the Lions competitive.
At some point, the defense has to start winning games for them, too.
