The Detroit Lions offensive line took a step backward last season, falling from a top-four unit in 2024 to a slightly above-average group in 2025. If the trend continues, Detroit’s hopes of returning to the playoffs could quickly slip away.
According to analysis from Pro Football Focus, the Lions’ biggest issues came along the interior of the offensive line. Left guard Christian Mahogany and center Graham Glasgow were identified as the weakest links in the unit.
Glasgow is no longer on the roster and has been replaced by Cade Mays on a value deal. However, Detroit still needs to strengthen the guard position and find a long-term replacement for veteran left tackle Taylor Decker.
Joel Bitonio Linked as Potential Lions Free-Agent Target
Gary Davenport of Bleacher Report recently named former Cleveland Browns guard Joel Bitonio as one of the best remaining free agents who could help the Lions return to the postseason in 2026.
“Not that long ago, the Detroit Lions fielded arguably the best offensive line in the NFL,” Davenport wrote. “There are still a few guards available on the open market, including one with seven Pro Bowls in the last eight years on his résumé.”
During the 2025 season with Cleveland, Bitonio played nearly 1,100 snaps and allowed just two sacks while committing only one penalty, according to Pro Football Focus. His experience and consistency could make him a valuable veteran addition for a Lions team looking to contend.
Bitonio Could Still Return to Cleveland
Bitonio will turn 35 early next season, and although he is approaching the later stage of his career, he remains a highly productive offensive lineman.
The veteran guard finished the 2025 season ranked 23rd among interior offensive linemen by Pro Football Focus out of 81 qualified players. Over his career, he has earned seven Pro Bowl selections and is widely viewed as a potential Hall of Fame candidate after retirement.
Bitonio played last season on a one-year $15 million deal. According to Spotrac, he could sign a contract worth just under $13 million for the 2026 season.
Despite being released by the Browns at the start of the league year in March after the sides failed to agree on an extension, the possibility of a return remains open.
Browns general manager Andrew Berry addressed Bitonio’s future during the NFL’s annual league meetings on March 30.
“Joel’s going to take the time that he needs to make the decision for the next step in his career,” Berry said. “It’s a pretty big life decision for him.”
Lions Expected to Target Left Tackle in the NFL Draft
While Detroit could explore adding a veteran guard, the team also has a major need at left tackle following Decker’s departure.
According to Ben Solak of ESPN, the Lions may look to address that position in the first round of the 2026 NFL Draft.
Solak noted that Larry Borom is a solid swing tackle but may not be the ideal long-term solution protecting quarterback Jared Goff on the blind side.
“With the 17th pick, the Lions are squarely in contention for a franchise left tackle,” Solak wrote.
General manager Brad Holmes has also suggested a possible lineup shuffle that could see Penei Sewell move to left tackle while Borom handles duties on the right side.
However, adding a proven veteran like Bitonio could stabilize the interior line and help Detroit regain its status as one of the NFL’s most dominant offensive fronts.
