Dan Campbell’s Aaron Glenn Comments Send Clear Message About Kelvin Sheppard

Dan Campbell spent part of Friday reflecting on his relationship with former Detroit Lions defensive coordinator Aaron Glenn, who is returning to Ford Field as head coach of the New York Jets. However, Campbell’s comments about Glenn may also provide insight into his current trust in defensive coordinator Kelvin Sheppard.

Kelvin Sheppard has been under pressure after a poor start to the 2026 season, with the Lions struggling to stop various aspects of the game. Campbell has faced questions about his confidence in Sheppard, but his response has been firm.

Campbell never lost faith in Glenn during his time with the Lions. Despite a difficult 2022, Glenn went on to help transform the team into a contender. Glenn, who Campbell called "one of my dearest friends," was a "right-hand man" in establishing the Lions' identity and standards. Campbell’s history with Glenn suggests he is willing to give Sheppard the benefit of the doubt, despite the team's struggles.

Sheppard has acknowledged the Lions' defensive issues, conducting a defensive self-scout after the loss to Buffalo. He identified that about 75% of the problems were self-inflicted and called for solutions, not finger-pointing. Campbell wants the same approach from Sheppard and isn't expecting perfection after just two games.

The Sunday matchup against the Jets will be interesting, with Campbell’s former trusted coordinator and the current defensive coordinator both on the sidelines. While it's too early to tell if Sheppard's situation will mirror Glenn's, Campbell’s history suggests he will give Sheppard ample opportunity to prove himself.
