Oklahoma State 2025 Position Preview: Defensive Line

Oklahoma State’s defense will need to be strong up front to turn things around in 2025.

This offseason was full of changes for the Cowboys, but the defense might be the most notable, especially up front. As the Cowboys look to produce a solid defensive unit again this fall, their biggest players will need to be ready to battle.

Although Todd Grantham’s additions through the portal will have to build chemistry and adjust to playing in Stillwater, there is no shortage of talent on the defensive line for the Pokes going into the season.

Defensive linemen on roster

DE Kyran Duhon, So.
DE Michael Riles, Fr.
DE Rashod Bradley, Jr.
DE DeSean Brown, R-Jr.
DE Landon Dean, R-Jr.
DE Armstrong Nnodim, R-Fr.
DE Jaleel Johnson, R-Jr.
DT Sitiveni Havili Kaufusi, R-Sr.
DT Austin Young, R-Fr.
DT Aden Kelley, R-Sr.
DT Michael Diatta, R-Sr.
DT De’Marion Thomas, Jr.
DT Luke Webb, R-Fr.
DT Iman Oates, R-Sr.

With a healthy mix of newcomers and returners in the middle and on the edge, OSU’s defensive line could come together quite quickly in 2025. Although there’s no guarantee the fit will be seamless, there should be plenty of reason for optimism up front.

Stars on the edge

UTEP transfer Kyran Duhon highlights OSU’s defensive ends. Earning a spot on the All-Conference USA Second Team as a freshman last season with 43 tackles and seven sacks, Duhon is arguably the best transfer OSU landed this offseason. Rashod Bradley, one of the nation’s top JUCO transfers, will also be looking to make an instant impact upon arrival in Stillwater.
