For a sixth-round pick, the path to relevance is usually supposed to be slow. Skylar Gill-Howard has not followed that script. After impressing during the OTA period, carrying that form into training camp and then posting an 88.4 PFF grade in Preseason Weeks 2-3, he has done enough to make the Lions depth chart a real conversation, not just a placeholder.
That matters because this is not a roster spot built on sentiment. It is a competition for snaps on the Detroit Lions defensive line, where even players already higher on the depth chart can feel the pressure when a rookie starts showing up with consistent production. Gill-Howard’s preseason did not just hint at upside; it gave the Lions a reason to keep re-evaluating who deserves playing time and in what order.
Why the grade matters
The 88.4 PFF grade in Preseason Weeks 2-3 is the cleanest snapshot of why Gill-Howard has pushed himself into the discussion. Among 162 qualifying interior defensive linemen, that level of performance stood out. He also posted a 17.9% pass-rush win rate, another sign that the results were not built on noise alone. For a young interior defender, that is the kind of number that can change how a coaching staff views the rotation.
The bigger point is not that preseason grades decide everything. They do not. But they do help identify when a player is doing more than surviving. Gill-Howard has looked like someone who can challenge established options rather than simply learn behind them. That is especially relevant on a defensive line where the Lions are balancing immediate depth with longer-term upside.
What it means for the rotation
The most direct effect is on Levi Onwuzurike and the rest of the group competing for interior snaps. The Lions believe Onwuzurike has top-level talent if he stays healthy, and that belief matters. But the final preseason game also showed how volatile these decisions can be, with Onwuzurike as Detroit’s lowest graded defender on PFF in that game before the team kept him on the roster during final cuts.
That is the tension now sitting under the Lions depth chart. Gill-Howard has earned a quicker look, while Onwuzurike remains a player the team still values highly. Those two ideas can coexist, but they also create real competition. If Gill-Howard keeps translating preseason production into reliable play, the Lions may not be able to treat him like a developmental afterthought for long.
That is what makes this story interesting. It is not just about a rookie flashing in August. It is about whether that flash was enough to force a change in how Detroit thinks about its interior defensive line. Right now, Gill-Howard has done the one thing that matters most for a late-round pick: he has made the Lions depth chart harder to write in pencil.
