Detroit enters training camp with continuity up front—and fierce competition behind it
The Detroit Lions head into 2025 with one of the most experienced starting offensive lines in the NFL. But behind that established unit lies a deep group of linemen fighting for limited roster spots. With rookies Tate Ratledge and Miles Frazier joining a crowded group of returning reserves, the battle in the trenches this summer could define the team’s long-term depth—and possibly even 2026’s starters.

TL;DR
- The starting five: Decker, Glasgow, Ragnow, Mahogany, Sewell
- Tate Ratledge and Miles Frazier will serve as top backups with developmental upside
- Detroit boasts versatile depth across both tackle and interior spots
- A few roster cuts are inevitable in what may be the most competitive position group on the team

Top Reserves and Depth

Giovanni Manu | OT | Size and athleticism make him a developmental project |
Kayode Awosika | OG/C | Valuable interior flexibility; reliable depth piece |
Netane Muti | OG | Physical run blocker; depth/spot duty option |
Colby Sorsdal | OT/OG | Versatile backup with starting experience at multiple spots |

Kingsley Eguakun | C | Undrafted center from 2024 competing for a PS spot behind Ragnow |
Key Position Battles to Watch
Backup Guard: Ratledge vs. Frazier vs. Muti
The Lions won’t carry four backup guards. Ratledge, the second-round rookie, is a near-lock for a roster spot and could be a future starter. Frazier brings strong pass-blocking upside but must prove his versatility. Netane Muti, though experienced, could find himself on the bubble if younger players step up.
Swing Tackle: Skipper vs. Manu vs. Sorsdal
Dan Skipper brings leadership and proven versatility, but he’ll need to hold off Giovanni Manu, a size-speed project with high upside, and Colby Sorsdal, who played valuable snaps in 2023. This might be a true three-man race, but it would not be surprising if Sorsdal or Manu get cut.
Development Watch: Christian Mahogany’s Growth
Christian Mahogany enters Year 2 as the starting right guard after replacing Kevin Zeitler. The Lions clearly trust him, but 2025 will be the year to prove he can consistently anchor the interior next to Sewell. Don’t be surprised if Tate Ratledge gets some rotational reps to push the second-year lineman and keep the pressure on.
The Bottom Line
The Lions’ starting five is locked in, but don’t let that fool you—this offensive line room might be the most competitive in camp. Between rookies with long-term potential and veterans fighting to stay relevant, the battle for backup spots will be fierce. If everyone stays healthy, this could be the deepest line of the Brad Holmes era—and that’s exactly how a contender builds from the inside out.
