Lions enter training camp with defensive and offensive line changes under review

Detroit will hold its first practice of the 2026 season on Wednesday, marking the start of training camp. Analysts note that linebacker Derrick Barnes, who signed a new contract last offseason, is expected to play a pivotal role on defense, expanding beyond his previous SAM duties and improving as both a coverage linebacker and pass rusher.

Cornerback Ennis Rakestraw, drafted shortly after the loss of Terrion Arnold, is viewed as a viable candidate for the starting CB2 position. Although Rock Ya-Sin currently holds the more trusted role, Rakestraw’s higher ceiling could earn him significant playing time.

Defensive end Levi Onwuzurike, who posted 13 quarterback hits and 45 pressures in 2024, is also considered a potential contributor to Detroit’s pass-rush improvement, despite past injuries and his age.

The Lions’ defensive scheme appears to be shifting toward a more athletic, pass-rush-oriented line. Recent roster moves—including the release of nose-tackle Jay Tufele and the addition of two Day-3 draft picks focused on pass rushing—suggest a willingness to sacrifice some run-stopping ability for greater pressure on quarterbacks. Coach Kelvin Sheppard has indicated an increased use of nickel packages, a change that could affect run-defense stability.

On the offensive side, the team’s line is undergoing a transition after the departures of Taylor Decker and Graham Glasgow. New center Cade Mays and first-round tackle Blake Miller are expected to bolster the unit, though analysts warn that chemistry will take time to develop as players adjust to new positions and partners.

The outlook for the 2026 season is tied closely to the development of the 2025 draft class. With limited free-agency additions, the Lions are relying on young players such as defensive tackle Tyleik Williams, who entered camp 50 pounds lighter, and offensive linemen like Tate Ratledge to step up. Wide receiver Isaac TeSlaa and special-teams hopeful Dominic Lovett are also mentioned as potential contributors.

Overall, the preseason will test the depth and adaptability of Detroit’s roster as the team seeks to improve on a year that saw more talent depart than arrive.
