1. Oklahoma

2. Clemson

Penn State ranks third. EDGE Dani Dennis‑Sutton (8.5 sacks last year) and disruptive interior tackle Zane Durant (11 tackles for loss) headline a unit packed with pedigree. Zuriah Fisher and Alonzo Ford Jr. are expected to emerge as key contributors . Steele notes some thin depth, but talent is elite .

Michigan earns number five despite replacing Mason Graham and Kenneth Grant. Up front, Derrick Moore and T.J. Guy anchor the edges, and transfer DT Tre Williams adds vital depth and stability .

 

6. Alabama

 

Steele slots Alabama at sixth, led by nose tackle Tim Keenan III, a run‑stopping force. Backup edge talent like Kelby Collins (a multi‑position Florida transfer) bolsters what is expected to be a powerful unit .

Texas Tech ranks seventh. After a defensive rebuild via the transfer portal, players like David Bailey (7 sacks at Stanford), Lee Hunter (UCF), and Skyler Gill‑Howard (NIU) give explosive ability up front .

At eighth, Iowa features a dependable group anchored by Aaron Graves (six sacks as a DT) and Ethan Hurkett (11 tackles for loss). Max Llewellyn brings upside to this consistently strong Big Ten line .

 

9. Texas
