Lions looking to new faces on the offensive line, with Blake Miller and Christian Mahogany tipped for starting roles

The Detroit Lions’ offseason offensive line reshaping is now being measured in the most practical way, with expectations for who will start when the games begin. According to Pro Football Rumors, rookie first-round tackle Blake Miller is viewed as the heavy favorite to be the Week 1 starter at his projected spot, while guard Christian Mahogany is still seen as the team’s preferred option to start at left guard.

The projections are tied to how the Lions plan to handle a major continuity issue at tackle and interior. In the club’s current scheme planning, the starting lineup is expected to reflect positional changes rather than a simple plug-and-play replacement. Pro Football Rumors reports that Detroit moved Penei Sewell from right tackle to left tackle, a specific change framed as part of the response to a key departure at the other spot.

That pivot matters because the Lions had Taylor Decker at the right tackle position, and Pro Football Rumors reports that Decker was released. With Decker no longer in the picture, the Lions’ approach has been to create a clear line of succession. The same report describes Blake Miller as a first-round pick selected with the idea that he could become Sewell’s immediate successor at right tackle, effectively aiming for a fast handoff of responsibilities.

Detroit’s interior mix is described as having another central piece in Christian Mahogany. Pro Football Rumors says Mahogany is still the leading candidate to start at left guard, indicating the Lions may view him as more than a depth option as they sort out the group after a season described in the report as involving significant regression along the offensive line.

Along with those internal answers, the Lions also added another name to the line mix in free agency. Pro Football Rumors reports that the team signed Cade Mays to man the pivot, pointing to a broader strategy of building competition across the middle spots rather than relying on only one returning option.

Taken together, the picture is not just about two individual players. It is about how Detroit wants to stabilize its protection and run-game structure by aligning roles across the line. When a team moves a cornerstone player like Sewell and couples that with a first-round investment for the other tackle spot, the expectation becomes that the unit is not waiting for development, it is expected to function immediately.

What to watch next is how those camp-and-roster expectations translate into the preseason and into the early-season lineup. Pro Football Rumors’ view is a forecast, not a roster guarantee, and the Lions’ final configuration will depend on how quickly the new tackle and guard plans fit together in practice and in game-week preparation.

The most important test of the Lions’ approach will arrive when the regular season forces the line to deal with a full slate of pass rush and movement packages from opposing defenses. If Miller and Mahogany hold up as starters as projected, Detroit’s offseason reset could look like a streamlined transition. If not, the Lions’ willingness to move parts will likely continue.

For now, the team’s “best guess” starters are centered on Miller at the right tackle spot, Mahogany at left guard, and Sewell operating on the left side. That combination would represent a clear chain of responsibility across the front, built to replace an earlier lineup and to limit the time the group spends without established structure.
