Lomu is a 6-foot-6, 308-pound tackle who logged 800 snaps at left tackle last season and allowed only two quarterback hits, according to PFF. The Utah product’s versatility stands out: he could start at guard initially and then slide outside if needed, giving the Lions roster-flexibility with an eye toward long-term projection at tackle.
Detroit’s front is positioned to absorb such a development. The Lions’ depth along the offensive line remains strong, even after the retirement of All-Pro center Frank Ragnow and the subsequent shifts that followed—Graham Glasgow moving to center and Taylor Decker aging toward 33 in 2026 with a sizable $21.1 million cap hit. An infusion like Lomu could provide a supplement without forcing an immediate overhaul.
Lomu’s fit with Dan Campbell’s scheme is a central point of the argument. While his run-blocking has lagged the development of his pass protection in college (a common area for growth), his balance, hand placement and anchor show promise, and NFL coaching could accelerate his progress. Zierlein notes Lomu’s power development and pad level as areas to improve, suggesting a quick trajectory with proper coaching.
Still, there are realities to consider. Zierlein also questions whether Lomu would be ready to start at left tackle right away, underscoring that his best initial role could be on the left of Decker or another veteran tackle before moving to the blind side in the longer term. The Lions’ decision on Lomu would hinge on whether he’s ready to contribute Day 1 or if he’s earmarked for a gradual developmental path.
Overall, the mock draft reflects a plausible scenario in which Detroit maintains its core offensive-line depth while pursuing a high-upside addition who could grow into a long-term starter. Caleb Lomu’s combination of durability, versatility, and developmental upside aligns with Campbell’s emphasis on flexibility along the line, providing a blueprint for how Detroit could balance immediate needs with future growth in the 2026 NFL Draft.
