Predicting the Detroit Lions Starting Defense Following 2026 NFL Draft

This group brings toughness and versatility.

Campbell continues to anchor the unit, Barnes adds physicality and range, and Rodriguez provides instincts and energy. It may not be flashy, but it fits the identity Detroit wants—fast, physical, and reliable.

Secondary

Cornerbacks:

• D.J. Reed
• Terrion Arnold
• Roger McCreary (Nickel)

Reed gives Detroit a proven veteran presence, while Arnold enters the season looking to bounce back healthy and make a major impact.

McCreary in the nickel role adds flexibility and toughness inside, giving the Lions a solid trio to match up with modern offenses.

Safeties:

• Kerby Joseph
• Christian Izien

This is the biggest question mark.

Joseph is a playmaker when healthy, but his return from injury will be something to monitor. Izien steps in as a versatile option who can stabilize the back end if needed.

The bottom line

This defense has potential.

The defensive line could be the strength, the linebackers bring stability, and the secondary has a mix of youth and experience.

The key?

Development and health.

If Derrick Moore emerges, if Terrion Arnold takes a leap, and if the safeties hold up, this unit could surprise people in 2026.

And if that happens, the Lions won’t just be good—they’ll be dangerous.
