The Detroit Lions are expected to return all five starting offensive linemen from their 2025 roster next season, but that doesn’t mean upgrades aren’t coming.

According to The Athletic’s Nick Baumgardner and Scott Dochterman, the Lions could target the offensive line in the first round of the 2026 NFL Draft. In their latest mock draft, the duo projected Detroit to select Utah offensive tackle Caleb Lomu with the No. 17 overall pick.

“The Lions’ offensive line could use a youth infusion, and Lomu, more than any of the other available offensive tackles, would fit perfectly with what Dan Campbell wants,” Baumgardner and Dochterman wrote. “He is durable (800 snaps at left tackle last season) and allowed only two quarterback hits all year, according to PFF. It’s possible he could step in at guard before shifting outside, if required.”

With veteran guard Graham Glasgow and left tackle Taylor Decker viewed by some analysts as potential cap casualties, Detroit could look to add a young, versatile lineman who can develop behind its current starters.

Caleb Lomu Profile and NFL Comparison

Standing 6-foot-6 and weighing 308 pounds, Lomu started two seasons at Utah and has already built a reputation as a reliable pass protector. NFL.com draft analyst Lance Zierlein compared him to Tennessee Titans left tackle Dan Moore Jr., citing his balance, punch timing, and grip strength in pass protection.

“Utah’s run game leaned heavily on movement and misdirection, preventing Lomu from firing out and showing his power,” Zierlein wrote. “His run blocking trails his pass protection, but improved pad level and a nastier demeanor could close the gap.”

Zierlein added that Lomu’s anchor and recovery skills give him a solid base to build on, and his development could accelerate with NFL strength training and coaching.

Why Lomu Fits Dan Campbell’s Lions

Lomu’s positional flexibility makes him a strong schematic fit for Dan Campbell’s physical brand of football. The Utah product could initially line up at guard or right tackle before eventually transitioning to left tackle in the future.

Because Detroit has veteran depth across the offensive line, Lomu would not be forced into an immediate starting role. That makes the Lions an ideal landing spot for a player still refining his technique.

“Lomu flashes but is still under construction,” Zierlein noted. “His play could improve rapidly with strength gains and additional coaching.”

Lions Offensive Line Outlook for 2026

The Lions enter 2026 with solid depth up front, even after the retirement of All-Pro center Frank Ragnow. Graham Glasgow shifted to center to replace him, creating ripple effects across the line that contributed to a decline in overall performance.

Detroit also has young players waiting for expanded roles, including former fourth-round pick Giovanni Manu.

However, concerns remain at left tackle, where Taylor Decker will be 33 years old before Week 1 of the 2026 season and carries a projected $21.1 million cap hit. That financial reality could force the Lions to explore younger, cheaper alternatives in the draft.

Long-Term Plan at Left Tackle

While Lomu may not be ready to immediately start at left tackle, his versatility gives Detroit long-term options. He could begin his career at guard or on the right side before eventually taking over the blindside role.

If Lomu develops as expected, the Lions could gain both short-term depth and a future franchise tackle — a “dream fit” for Campbell’s offense.
